Familial streblodactyly with amino-aciduria is a very rare genetic condition that tends to run in families. The finger joints—usually the little fingers—bend and stay partially flexed (camptodactyly). At the same time, the kidneys pass a lot of the amino acid “taurine” into the urine (taurinuria). In the few families described, most people were otherwise healthy, and the extra taurine in urine did not cause illness. There is no disease-specific drug. Care focuses on gentle hand therapy, splinting, and, if function is clearly limited and therapy fails, selective surgery. The amino-acid finding is monitored, but usually needs no treatment because isolated taurinuria is considered benign. ScienceDirect+3PubMed+3PubMed Central+3
Familial streblodactyly with amino-aciduria—better known today as camptodactyly-taurinuria syndrome—is a very rare inherited condition. People are born with one or more fingers bent and hard to straighten (this is called camptodactyly). They also pass too much of the amino acid taurine into their urine (this is called taurinuria). The little finger is often the most affected, but any finger can bend. The condition seems to run in families in an autosomal dominant way, which means it can pass from one parent to a child. Only a small number of families—about 17 people in 4 families—have been reported in the medical literature, and most reports are older (1960s). rarediseases.info.nih.gov+2Orpha+2

Doctors first described this exact combination (bent fingers plus taurine in the urine) in a British Medical Journal report in 1963, calling it “familial streblodactyly with amino-aciduria.” Later summaries from rare-disease databases (GARD/Orphanet/MedGen) use the name camptodactyly-taurinuria syndrome for the same disorder. NCBI+3BMJ+3rarediseases.info.nih.gov+3
Camptodactyly itself happens when the joint in the middle of the finger (the PIP joint) stays flexed (bent). Research in camptodactyly (not specific to this rare syndrome) shows that an imbalance of the finger’s flexor and extensor forces—often related to intrinsic muscle (lumbrical) anomalies or tendon problems—can hold the finger in a bent position. This helps explain the finger posture seen in this syndrome. jhandsurg.org+2PubMed+2
The taurine part is biochemical: taurine is an amino acid the body uses for many jobs (like helping cells handle salts and supporting muscle and heart function). Too much taurine in urine suggests changes in transport or handling of taurine by the body (for example, changes in the TauT/SLC6A6 transporter in other models). While the exact genetic change in this specific syndrome has not been pinned down in the literature, modern studies in animals show how taurine transport affects body tissues, which supports the plausibility of the “taurinuria” feature. PubMed Central+2faseb.onlinelibrary.wiley.com+2
Overall, the prognosis is usually good: the bent fingers may affect hand function to different degrees, but life expectancy is normal, and the main medical finding outside the hands is the excess taurine in urine. Wikipedia
Other names
Camptodactyly-taurinuria syndrome
Familial streblodactyly with amino-aciduria (historic name)
Sometimes listed under MONDO:0015272 / UMLS C4518792 in databases. NCBI+3Orpha+3Orpha+3
Types
Because so few families are reported, doctors group “types” mainly by how the fingers are involved and by severity, borrowing from the general camptodactyly literature:
Isolated little-finger type – only the little finger is bent. rarediseases.info.nih.gov
Multiple-finger type – several fingers are bent on one or both hands. rarediseases.info.nih.gov
Severity groups – mild (bends a little, straightens partly), moderate (not fully straightenable), severe (fixed contracture that limits daily tasks). These severity ideas come from broader camptodactyly care pathways. Orthobullets+1
Unilateral or bilateral – one hand or both hands involved (both can occur). Thieme
Note: Some papers classify camptodactyly into “Type I (childhood), Type II (adolescent), Type III (syndromic).” In this rare syndrome, the “syndromic” label simply means the bent fingers occur together with taurinuria. Thieme
Causes
Because this condition is extremely rare, exact causes in each family are not fully worked out. The list below explains what is known or reasonably inferred from reported families and from research on camptodactyly and taurine handling. Where evidence comes from broader camptodactyly or taurine-transport science, I say so.
Autosomal dominant inheritance – runs in families, often parent to child, matching old family reports. rarediseases.info.nih.gov+1
Intrinsic muscle anomaly (lumbricals) – small hand muscles may attach abnormally, pulling the PIP joint into flexion. (Evidence from general camptodactyly surgery studies.) jhandsurg.org+1
Flexor–extensor tendon imbalance – the forces that bend vs. straighten the finger are not balanced. (General camptodactyly mechanism.) Orthobullets+1
Abnormal origin/insertion of flexor tendons – tendons may run in a way that keeps the joint bent. (Case reports in camptodactyly.) Thieme
Tight skin or joint capsule – soft tissues around the joint may be shortened, limiting extension. (Common in camptodactyly.) Orthobullets
Connective-tissue patterning during fetal development – small changes while the hand forms can leave the joint flexed. (General developmental reasoning consistent with camptodactyly literature.) ScienceDirect
SLC6A6 (TauT) transporter biology – while not proven in these historic families, taurine handling depends on TauT; changes in taurine transport are a biologic basis for taurinuria. (Animal and cell studies.) PubMed Central+1
Renal handling of taurine – kidneys control how much taurine is kept or lost; benign amino-aciduria forms can raise urinary taurine. (General taurine excretion physiology.) ScienceDirect
Modifier genes – even with the same main gene, other genes may affect how bent the fingers are. (Explains variable expressivity seen in camptodactyly.) Wikipedia
Postnatal soft-tissue adaptation – as a child grows, the bent position can tighten tissues further. (Known in camptodactyly progression.) jprasurg.com
Intra-family variation – family reports show some relatives have milder or more severe bending, hinting at complex causes. (Historic families.) BMJ
Hormonal/growth influences – growth spurts can unmask or worsen flexion deformities in general camptodactyly. The Plastics Fella
Neuromuscular tone patterns – muscle tone distribution can keep PIP joints flexed (general principle in hand deformities). Orthobullets
Abnormal lumbrical path across the PIP joint – specific surgical/anatomic findings support this. jhandsurg.org
Small finger predominance – the little finger’s mechanics make it more vulnerable to fixed flexion. (Observed repeatedly.) rarediseases.info.nih.gov
Benign generalized amino-aciduria traits – some families pass mild amino-acid leak states; taurine may be prominent. (General renal amino acid transport understanding.) ScienceDirect
Epigenetic factors – how genes switch on/off may influence severity (a reasonable hypothesis for variable expressivity). Wikipedia
No environmental trigger required – this syndrome appears congenital and genetic; no exposures are known to be necessary. (Rare-disease summaries.) rarediseases.info.nih.gov
Normal diet can still show high taurine in urine – taurine excretion fluctuates with intake, but the syndrome shows persistent elevation. (Diet studies + rare-disease descriptions.) ScienceDirect+1
Unknown primary gene – in the classic families, a single causative gene was not identified; the pattern looked dominant. (Historical reports + Orphanet/GARD.) BMJ+1
Symptoms
Bent finger(s) at the PIP joint – the middle joint stays flexed and does not fully straighten. Orthobullets
Little finger often most affected – the small finger commonly shows the bend first or most strongly. rarediseases.info.nih.gov
One or both hands – either hand may be involved; sometimes both hands. Thieme
Appears in infancy/childhood – present at birth or noticed early in life. Orpha
Progressive tightness – without stretching/splinting, tissues may tighten and bending can worsen with growth. jprasurg.com
Limited reach or grip – severe cases make it hard to grasp wide objects or place the hand flat. (General to camptodactyly.) Orthobullets
Family history – more than one family member across generations may be affected. BMJ
Normal feeling and circulation – sensation and blood flow are usually normal because the issue is mechanical/soft tissue. (Typical for camptodactyly.) Orthobullets
No general illness – people are otherwise healthy; the main lab finding is taurine in urine. (Syndrome descriptions.) rarediseases.info.nih.gov
Taurinuria (high taurine in urine) – biochemical sign seen on amino-acid testing. BMJ
Usually no pain at rest – fingers feel tight more than painful; pain can occur if joints are forced. (General to contractures.) Orthobullets
Variable severity within a family – some relatives have mild bends; others are more fixed. BMJ
No known systemic organ disease from taurine loss in these historical families (unlike severe transporter knockouts in animals). BMJ+1
Normal life span – overall prognosis good. Wikipedia
Cosmetic concern – some people mainly want the finger to look straighter even if function is fair. (Typical in hand clinics.) Orthobullets
Diagnostic tests
A) Physical examination (bedside assessment)
Inspection of finger posture – doctor looks for fixed PIP flexion and which fingers are involved. (Core exam.) Orthobullets
Passive range of motion – gently pushing to see how much the joint can straighten; limited extension suggests contracture. Orthobullets
Active range of motion – patient tries to straighten; limited active extension with better passive extension may indicate muscle imbalance. jhandsurg.org
Assessing both hands – to compare severity and see if the pattern is bilateral. Thieme
Functional tasks – grip, pinch, placing hand flat on a table; shows real-life impact. Orthobullets
B) Manual/special hand tests
Bunnell (intrinsic tightness) test – compares PIP motion with MCP joint flexed vs. extended to detect intrinsic muscle tightness (commonly used in hand deformities). Orthobullets
Tendon glide assessment – checks whether flexor/extensor tendons move smoothly, suggesting imbalance rather than joint disease. Hand Surgery Resource
Splint-response trial – several weeks of night splinting to see if extension improves; response supports soft-tissue tightness. jprasurg.com
Contracture angle measurement – goniometer reading to track degrees of fixed flexion over time. Orthobullets
Provocative stretch tests – gentle, progressive stretches; if tissue length improves, it argues against bony block. Orthobullets
C) Laboratory / pathological
Urine amino-acid profile (quantitative) – confirms elevated taurine (taurinuria), the biochemical hallmark. BMJ
Repeat urine taurine after normal diet – shows that taurine remains high beyond temporary diet effects. ScienceDirect
Plasma amino acids – usually normal; helps exclude wider amino-acid disorders. (Supportive step.) rarediseases.info.nih.gov
Basic renal panel (creatinine, urinalysis) – kidney function is typically normal; this helps rule out renal disease. (Syndrome descriptions.) rarediseases.info.nih.gov
(If research/availability) genetic testing panels – although no specific gene is confirmed for historic families, modern panels may include SLC6A6 and hand-malformation genes to explore mechanisms. monarchinitiative.org+1
D) Electrodiagnostic
Nerve conduction studies – usually normal; used to exclude neuropathic causes of finger posture if exam is atypical. (General hand evaluation.) Orthobullets
Electromyography (EMG) – can document intrinsic muscle activity patterns when the diagnosis is uncertain; typically not required in classic cases. (General principle.) jhandsurg.org
E) Imaging
Plain X-rays of the hand – bones/joints usually formed; helps rule out bony blocks or other anomalies. (Standard in camptodactyly work-up.) Orthobullets
Ultrasound of tendons – can show tendon position or abnormal muscle slips that might pull the PIP joint. (Supported by camptodactyly anatomy reports.) jhandsurg.org
MRI (selective) – detailed look at soft tissues (intrinsic muscles, tendons, pulleys) when surgery is considered. (Used in complex hand deformities.) Orthobullets
Non-pharmacological treatments (therapies & others)
Hand therapy program – A therapist teaches gentle passive stretching of the affected PIP joints, tendon-gliding drills, and functional tasks. This is the first-line approach and should be individualized for age and severity. Evidence quality is low but consistently favors therapy as baseline care. PubMed Central+1
Static extension splinting – Night-time static splints hold the finger straighter to remodel soft tissue over months. Schedules vary (e.g., 15–18 h/day in some protocols) and should be adjusted to comfort and skin tolerance. MDPI
Dynamic splinting – Spring-loaded or elastic orthoses apply a gentle, continuous extension force during waking hours early in treatment, later transitioning to night wear. Useful for progressive deformity in young children. MDPI
Serial casting – Short series of well-padded extension casts progressively increase range when splints alone are insufficient. Casting is time-limited and followed by splints and therapy to maintain gains. PubMed Central
Home stretching plan – Simple daily routines (short, frequent holds) help maintain extension. Education on safe hand positions reduces over-flexion habits. PubMed Central
Activity modification – Brief breaks from prolonged gripping, gaming, or tool use; using larger-diameter pens or adaptive grips to reduce flexion stress. PubMed Central
Occupational therapy for function – Task-oriented training (typing, writing, buttoning) with adaptive strategies improves independence even if some contracture persists. PubMed Central
Heat (paraffin or warm soaks) before stretch – Gentle heat increases tissue pliability and comfort prior to exercises or splinting; avoid burns and over-heating. PubMed Central
Cold packs after long sessions – Brief, wrapped cold application may reduce post-stretch soreness and swelling when needed. PubMed Central
Kinesiology or rigid taping – Temporary external support can cue extension and reduce flexion bias during activities; evidence is anecdotal and low-quality. PubMed Central
Ergonomic tools – Built-up handles, light-force scissors, and supportive keyboards minimize sustained PIP flexion. PubMed Central
School accommodations – Extra time for writing, permission for keyboards, and adapted physical education help children participate fully. PubMed Central
Monitoring for progression – Regular angle measurements (e.g., every 3–6 months in growing children) catch worsening early and guide intensity of splinting. PubMed Central
Family training – Parents/caregivers learn splint care, skin checks, and how to support exercises to improve adherence and outcomes. PubMed Central
Psychosocial support – Body-image and participation support, especially in teens, can improve quality of life when hand appearance differs. PubMed Central
Hydrotherapy – Warm-water movement may ease stretching and functional practice; used as an adjunct rather than a stand-alone therapy. PubMed Central
Structured adherence plan – Simple logs, reminders, and regular therapist check-ins improve consistency with splints and exercise. PubMed Central
Multidisciplinary clinic – Coordination among hand surgery, hand therapy, pediatrics, and genetics/metabolics ensures whole-person care and rational testing of aminoaciduria. PubMed Central+1
Education about benign taurinuria – In this syndrome, high urinary taurine has not been shown to cause harm; reassurance reduces unnecessary restrictions. PubMed Central+1
General fitness & posture – Balanced upper-limb strength and posture may reduce compensations from restricted finger motion; integrate with therapy goals. PubMed Central
Drug treatments
There are no FDA-approved drugs for “familial streblodactyly with amino-aciduria.” Medicines, when used, address symptoms around therapy or surgery (e.g., pain control) or unrelated issues. Doses below are label-based general ranges and must be individualized by a clinician. Listing here does not imply that a drug treats the underlying syndrome. PubMed
Acetaminophen – For short-term pain flares around intensive therapy. Class: analgesic. Typical adult dosing 325–1000 mg per dose, max per FDA labeling; pediatric weight-based. Watch total daily dose and liver risk. PubMed
Ibuprofen – NSAID option for activity-related soreness; adult 200–400 mg per dose OTC per label; pediatric weight-based. GI, kidney, and bleeding cautions. (FDA OTC monograph/labeling principles.) PubMed
Naproxen – Longer-acting NSAID for daytime symptoms when needed; adult OTC 220 mg; Rx strengths exist; GI and CV warnings per label. PubMed
Topical diclofenac 1% gel – Local NSAID gel rubbed onto sore periarticular tissues; minimizes systemic exposure; follow label dosing limits. PubMed
Celecoxib – COX-2 selective NSAID for patients who need an NSAID but are at higher GI risk; CV risk remains. Prescription only; use lowest effective dose. PubMed
Lidocaine 5% patch (localized pain) – Provides local anesthetic effect for tender dorsal PIP soft tissues; apply on intact skin, observe max number of patches and hours/day per label. PubMed
Short peri-operative antibiotic (e.g., cefazolin) – Standard surgical prophylaxis if surgery is performed; timing, dose, and redosing per label and peri-op guidelines. Not syndrome-specific. jhandsurg.org
Ondansetron – For post-operative nausea if surgery is needed; dosing and QT warnings per label. PubMed
Acetaminophen + NSAID rotation – Label-guided alternating strategy under clinician advice to reduce single-agent load; monitor totals and risks. PubMed
Proton-pump inhibitor (e.g., omeprazole) – Consider short-term GI protection in at-risk NSAID users; follow label indications and durations. PubMed
Baclofen (muscle relaxant) – Rarely, if muscle over-activity contributes to discomfort with stretching; start low; sedation risk; off-label for this use. PubMed
Short-course oral steroid (peri-operative edema control) – Occasionally used by surgeons after extensive soft-tissue release; risks often outweigh benefits; case-by-case only, per label cautions. jhandsurg.org
Topical anesthetic cream (lidocaine/prilocaine) – To improve comfort with splint adjustments or cast removal in sensitive children; follow label site/age limits. PubMed
Gabapentin (neuropathic pain) – Only if neuropathic features appear post-op; renal dosing and sedation warnings per label. Not routine. PubMed
Acetaminophen-opioid combinations – Reserved for immediate post-op breakthrough pain, shortest possible duration, strict label limits due to dependency and liver risk. jhandsurg.org
Topical NSAID patch (diclofenac epolamine) – Alternative local NSAID delivery with label-specified on/off times. PubMed
Antibiotic alternative for β-lactam allergy (e.g., clindamycin) peri-op – Only if surgery occurs and indicated by institutional protocols. jhandsurg.org
Acetaminophen IV (peri-op) – Used intra/post-op to reduce opioid need; observe label max daily dose including oral sources. jhandsurg.org
Stool softener (docusate) if short opioid course – Symptom management per label; avoid chronic use without indication. PubMed
Antihistamine (ondansetron alternative interactions considered) – For nausea in select cases where serotonin-antagonist is contraindicated; follow label guidance. PubMed
Again, these medications do not treat the syndrome itself; they’re supportive around therapy or surgery and must be prescribed by a clinician familiar with the patient.
Dietary molecular supplements
Taurine – Paradoxically, even with taurinuria, people are typically well. Supplementing taurine is not routinely required; any use should be cautious and supervised. Taurine plays roles in osmoregulation and membrane stabilization; urinary excretion largely tracks intake. Evidence for benefit in this syndrome is lacking. PubMed Central+1
Vitamin D – Supports bone and muscle function, helpful for general hand strength alongside therapy; dose individualized per level testing; no syndrome-specific data. PubMed Central
Omega-3 fatty acids – General anti-inflammatory nutritional support; may help exercise tolerance in some musculoskeletal contexts; no direct evidence in camptodactyly. PubMed Central
Vitamin C – Collagen cofactor; theoretical support for tendon/skin health when dietary intake is low; avoid mega-doses. PubMed Central
Magnesium – Adequate intake supports muscle relaxation and nerve function; correct deficiencies only. PubMed Central
Protein adequacy – Ensuring age-appropriate protein intake helps general tissue maintenance; more is not necessarily better. PubMed Central
B-complex (esp. B6, B12, folate) – Correct documented deficiency to support neuromuscular health; routine high-dose supplementation not advised without need. PubMed Central
Collagen peptides – May support tendon health in athlete literature; evidence is mixed; can be tried short-term with therapy. PubMed Central
Glycine – A structural amino acid in collagen; theoretical support only; prioritize balanced diet first. PubMed Central
N-acetylcysteine (NAC) – Precursor in sulfur-amino-acid pathways; no direct role here; avoid casual long-term use without clinician supervision. PubMed Central
Important: Supplements should never replace therapy/splinting; discuss with a clinician, especially in children.
Immunity booster / regenerative / stem-cell drugs
There are no immune or stem-cell drugs indicated for this syndrome. Below are concepts sometimes discussed in musculoskeletal care or nutrition—not recommended as disease treatments here. This is for context only. PubMed
Taurine (nutraceutical) – Cytoprotective and osmoregulatory roles; not an immune drug; routine use isn’t indicated for taurinuria alone. PubMed Central
Vitamin D (hormone-like nutrient) – Supports innate immunity and bone/muscle health when deficient; correct deficiency only. PubMed Central
Omega-3s – Modulate eicosanoids; general anti-inflammatory effects but no disease-specific indication. PubMed Central
Collagen peptides – Nutritional substrate, not regenerative drug; evidence limited. PubMed Central
Platelet-rich plasma (PRP) – Occasionally used for tendinopathies; not indicated for camptodactyly deformity; no evidence here. PubMed Central
Stem-cell injections – Not recommended; no evidence or regulatory approval for this condition. PubMed
Surgeries (what they are and why)
Surgery is only for fixed deformities that limit function after a well-documented trial of therapy/splints. Even then, expectations should be cautious, and night splinting continues post-op. jhandsurg.org+1
Flexor digitorum superficialis (FDS) tenotomy/lengthening – Releases a tight FDS to allow more PIP extension. Chosen when the FDS is the primary tether. Goal: improve function such as grasp and hygiene. jhandsurg.org
Lumbrical or intrinsic muscle release – If anomalous insertion causes flexion pull, selective release reduces deforming force. Goal: better active extension after therapy. jhandsurg.org
Volar skin Z-plasty / local flap – When skin contracture limits extension, lengthening the volar skin permits straighter posture; must be combined with soft-tissue balancing. jhandsurg.org
Tendon transfer or central slip reinforcement – In select cases to rebalance extension mechanism; requires intensive rehab. jhandsurg.org
PIP arthrodesis (fusion) in functional position – Last-line for painful, rigid deformity in adults; sacrifices motion to gain stability and alignment. jhandsurg.org
Preventions
Because this is a genetic trait in reported families, prevention of the trait is not possible; the focus is preventing stiffness progression and secondary problems. PubMed
Early referral to hand therapy once a contracture is noticed. PubMed Central
Consistent splint wear schedule with skin checks. MDPI
Avoid long periods of strong finger flexion (gaming, tight grip) without breaks. PubMed Central
Use ergonomic grips and larger-barrel pens. PubMed Central
Warm-up before stretching; avoid forceful, painful stretches. PubMed Central
Maintain general fitness and hand strength with therapist-guided exercises. PubMed Central
Keep routine pediatric/primary-care visits; monitor growth and function. PubMed Central
Seek genetics counseling for family planning discussion, recognizing evidence is limited. PubMed
Balanced diet to support normal growth; avoid extreme supplement use. PubMed Central
Post-op adherence to night splints and therapy to prevent recurrence if surgery is done. jhandsurg.org
When to see a doctor
See a clinician (hand surgeon/therapist or pediatrician) if: the finger bend is increasing over months; the finger can’t straighten enough for hygiene or grasp; pain or swelling persists; splints cause skin breakdown; school tasks become hard; or if there are questions about unusual lab results like aminoaciduria. Families with a history of similar hands and “taurine in urine” should request documented evaluation and counseling. PubMed Central+1
What to eat… and what to avoid
Eat a normal, age-appropriate, balanced diet—fruits, vegetables, whole grains, adequate protein, and calcium/vitamin D sources—because good nutrition supports therapy and growth. There’s no special “streblodactyly diet.” Seafood and meats naturally contain taurine; urinary taurine tends to follow intake and, by itself, is not harmful—so there’s no need to avoid taurine-containing foods unless a clinician advises otherwise. Avoid megadose supplements or restrictive fad diets; they don’t treat the condition and can cause other problems. MDPI+1
FAQs
1) Is this the same as sclerodactyly or ectrodactyly?
No. Sclerodactyly is skin tightening from scleroderma, and ectrodactyly is split-hand/foot. This syndrome involves camptodactyly (bent fingers) with taurinuria and is distinct. MedlinePlus+2Wikipedia+2
2) What causes it?
Unknown. It’s described as familial (likely autosomal dominant) but the gene isn’t known. Only a few families were reported historically. PubMed+1
3) Does extra taurine in urine harm the kidneys?
No clear evidence of harm when taurinuria is isolated. Taurine excretion often mirrors intake; isolated taurinuria is generally benign. PubMed Central+1
4) Can therapy straighten the finger completely?
Sometimes therapy and splints improve extension, especially in younger children; results vary and evidence quality is modest. PubMed Central
5) When is surgery considered?
After months of well-done therapy/splinting when the contracture blocks function or hygiene. Post-op night splints and therapy remain essential. jhandsurg.org
6) Are there medicines that fix the bent finger?
No. Medicines are for pain control around therapy or surgery; they don’t correct the contracture. jhandsurg.org
7) Should we limit taurine-rich foods?
Not routinely. Dietary taurine largely drives urinary taurine, but isolated taurinuria isn’t a disease by itself. Ask your clinician before any restriction. MDPI+1
8) Could this be part of another syndrome?
Camptodactyly occurs in many conditions; careful exam and history help rule out other causes. In the historical families, the pattern was otherwise uncomplicated. PubMed Central
9) What tests are useful?
Clinical hand exam with goniometry; occupational/hand therapy assessment; urine amino acids to document taurinuria; broader aminoaciduria panel if clinically indicated. PubMed Central+1
10) Can it affect toes?
Reports focused on fingers, especially the little finger; distribution may vary. PubMed
11) Does it get worse with age?
Progression can occur during growth, which is why early therapy and monitoring help. PubMed Central
12) Is genetic testing available?
There is no known gene for this exact syndrome; a genetics visit can still help exclude other disorders and guide family planning. PubMed
13) Are stem-cell or PRP injections helpful?
No evidence or approval for this condition. Avoid unproven procedures. PubMed
14) Could taurinuria signal a broader tubular problem?
Generalized aminoaciduria can occur in renal tubular disorders, but in this syndrome reported taurinuria was isolated. Clinicians decide when to look deeper. ScienceDirect
15) What is the outlook?
Most individuals lead normal lives. The goal is comfortable function through therapy, splints, and, rarely, surgery. PubMed Central
