Berk–Tabatznik syndrome (BTS) is an ultra-rare congenital condition described in only a few patients. The consistent features across reports are: short stature, congenital optic atrophy (the optic nerve is under-developed from birth, causing vision loss), and brachytelephalangy (shortened end bones of the fingers). Some patients also had cervical spine abnormalities (kyphosis and small cervical vertebral bodies) and neuromotor problems such as spasticity and difficulty walking. The exact cause is unknown. PubMed+2Wiley Online Library+2
Berk–Tabatznik syndrome—also called kyphosis-brachyphalangy-optic atrophy—is a very rare condition marked by short stature, congenital optic atrophy (reduced optic-nerve function from birth), brachytelephalangy (short end bones of the fingers), and sometimes cervical spine changes. Fewer than a few cases have been published, and the cause is still unknown. Management is supportive and symptom-guided, best delivered by a multidisciplinary team (genetics, ophthalmology, orthopedics, neurology/physiatry, cardiology if needed, audiology, rehabilitation). PubMed+2Wiley Online Library+2
BTS is sometimes grouped under heart–hand syndromes in differential lists; however, BTS itself is primarily defined by optic atrophy + brachytelephalangy ± cervical anomalies, and reports are extremely sparse. When heart issues are suspected, cardiology evaluation is warranted. Lippincott Journals+1
Berk–Tabatznik syndrome is a pattern of findings present from birth. Children are often smaller than peers (short stature). Their optic nerves do not fully carry visual signals, so central vision can be weak (congenital optic atrophy). The last bones of some fingers are short (brachytelephalangy), so fingertips can look a little shortened or broad. Some people have neck-spine shape differences (cervical kyphosis/wedging) and may develop stiffness or weakness that affects posture. Hearing may also be less than normal. Doctors do careful eye tests, hand X-rays, and spine imaging to understand the exact picture. No single gene or cause is confirmed. Treatment is about protecting vision, optimizing function, supporting learning and daily living, and preventing complications over time. PubMed+1
Clinically, you can think of BTS as a constellation of eye, hand, and growth/spine findings present from early life. Because it is so rare, the diagnosis is usually made by an experienced clinical geneticist after other, more common conditions are ruled out. Wikipedia+1
Other names
Published and ontology sources list several alternative labels for the same or closely overlapping phenotype. You may encounter: “Berk–Tabatznik syndrome,” “Berk Tabatznik syndrome,” “congenital optic atrophy and brachytelephalangy,” “kyphosis–brachyphalangy–optic atrophy,” and terms combining cleft/hand shortness/short stature–dwarfism in older indexing. Some summaries also align BTS under “heart–hand syndrome type 2” in broader “heart–hand” taxonomies, though cardiac involvement is not consistently documented for BTS itself; treat that mapping cautiously. next.monarchinitiative.org+4National Organization for Rare Disorders+4Wiktionary+4
Types
Because only one or two detailed case reports exist, no official subtypes are established. For clinical communication, some authors describe:
“Core phenotype”: short stature + congenital optic atrophy + brachytelephalangy.
“Expanded phenotype”: core features plus cervical spine hypoplasia/kyphosis and spasticity.
These are descriptive, not formal types; they simply reflect what has been observed so far. PubMed+1
Possible causes
Important: The cause of BTS is unknown—no gene has been confirmed. The list below explains plausible mechanisms clinicians consider for similar congenital triads (optic nerve, distal phalanx, spine/growth) and why each is considered. These items are hypotheses, useful for guiding testing and counseling, not proven facts for BTS.

Diagnostic tests
Below is a pragmatic, clinic-to-lab pathway. Because BTS is a diagnosis of exclusion with overlapping features from other syndromes, testing aims to 1) document the triad, 2) map spine/hand anatomy, 3) grade vision and neurologic tone, and 4) search for a genetic cause.
A) Physical examination
Detailed growth assessment (height/weight/head circumference; growth percentiles). Confirms short stature pattern over time. Wikipedia
Hand inspection and measurement (finger length; nail shape). Screens for brachytelephalangy; formal anthropometry if available. Wikipedia

Drug treatments
There are no FDA-approved drugs for Berk–Tabatznik syndrome itself. The medicines below are commonly used—when appropriate—to treat symptoms seen in some people with BTS (spasticity, neuropathic pain, musculoskeletal pain, anxiety/sleep, and possible heart rhythm issues). Always individualize with a clinician; dosing varies by age, kidney/liver function, and co-morbidities. To meet your request, I cite representative FDA labels to document each drug’s class/indications; use is for the relevant symptom, not for BTS per se.
Baclofen (oral; e.g., Lyvispah/Ozobax/Kemstro) – GABA_B agonist muscle relaxant
Class & Purpose: Antispasticity; helpful for increased tone or painful spasms.
Typical dosage/time: Start low (e.g., 5 mg 1–3×/day in adults) and titrate; pediatric dosing is weight-based. Do not stop abruptly.
Mechanism: Activates spinal GABA_B receptors, dampening excitatory reflexes and reducing spasticity.
Key cautions/side effects: Drowsiness, dizziness, weakness; withdrawal can be severe if stopped suddenly (hallucinations, seizures, rebound spasticity). FDA Access Data+1Tizanidine (Zanaflex) – central α2-adrenergic agonist
Class & Purpose: Short-acting antispasticity agent for function-critical times.
Dosage: Often 2–4 mg up to every 6–8 h as needed; adjust for liver function.
Mechanism: Increases presynaptic inhibition of motor neurons, reducing muscle tone.
Side effects: Sedation, hypotension, dry mouth; additive CNS depression with alcohol/benzos. FDA Access DataGabapentin (Neurontin/Gralise) – neuromodulator
Class & Purpose: Neuropathic pain and paresthesia control.
Dosage: Titrated; e.g., adults 300 mg once to three times daily initially; adjust for kidney function.
Mechanism: Binds α2δ subunit of voltage-gated calcium channels → reduces excitatory neurotransmission.
Side effects: Dizziness, somnolence; taper to discontinue. FDA Access Data+1Duloxetine (Cymbalta) – SNRI
Class & Purpose: Neuropathic pain and chronic musculoskeletal pain; also treats anxiety/depression that can accompany chronic disability.
Dosage: Commonly 30–60 mg daily in adults.
Mechanism: Boosts spinal descending inhibition of pain by increasing serotonin/norepinephrine.
Side effects: Nausea, dry mouth, sweating, BP/HR changes; black-box for suicidality in youth. FDA Access DataAcetaminophen (paracetamol) – analgesic/antipyretic
Purpose: First-line for aches without inflammation.
Dosage: Follow age-specific max daily dose; watch combined products.
Mechanism: Central prostaglandin inhibition (exact mechanism complex).
Side effects: Liver toxicity in overdose (avoid with liver disease). (OTC monograph; include only under clinician guidance in children.)NSAIDs (e.g., ibuprofen, naproxen, meloxicam) – anti-inflammatory analgesics
Purpose: Activity-related musculoskeletal pain from posture/strain.
Dosage: Age/weight-based; take with food; avoid if GI/renal risk.
Mechanism: COX inhibition → lower prostaglandins → less peripheral sensitization.
Side effects: GI upset/bleeding risk, kidney strain, BP elevation. (Use the lowest effective dose.)Topical NSAIDs (diclofenac gel)
Purpose: Local joint/tendon pain with fewer systemic effects.
Mechanism: Local COX inhibition.
Cautions: Avoid on broken skin; watch total NSAID burden.Magnesium (for muscle cramps if deficient)
Purpose: May ease cramp frequency when deficiency exists.
Mechanism: Repletes intracellular Mg²⁺, stabilizing neuromuscular excitability.
Cautions: Diarrhea; caution in renal impairment.Melatonin (sleep initiation)
Purpose: Improve sleep onset in visually impaired individuals with circadian drift.
Mechanism: Resets circadian receptors (MT1/MT2).
Cautions: Daytime drowsiness; discuss dosing timing.Propranolol or Metoprolol (if cardiology indicates arrhythmia/rate control) – β-blockers
Purpose: Manage certain tachyarrhythmias or rate control when a cardiologist confirms need.
Mechanism: β1-blockade reduces AV-nodal conduction and myocardial oxygen demand.
Cautions: Asthma (propranolol), hypotension, bradycardia. (Representative FDA labeling shown for metoprolol.) FDA Access DataCalcium/vitamin D (when deficient)
Supports bone health if intake is low or labs show deficiency.Topical capsaicin or lidocaine patches for focal neuropathic pain
Desensitize TRPV1 fibers (capsaicin) or block sodium channels (lidocaine).Diazepam (rare, short-term) for severe spasms/anxiety
Benzodiazepine muscle-relaxant properties; strong caution for sedation and dependence.Clonidine (night spasms or sleep in select cases)
Central α2 agonist; may reduce hyperarousal.Botulinum toxin injections (focal spasticity)
Local chemodenervation to improve ROM or hygiene tasks.Proton-pump inhibitor “on board” only when NSAID-GI risk requires
Stomach protection strategy under medical advice.Iron supplementation if iron-deficient
Improves fatigue and supports growth.Thiamine/B-complex if documented deficiency
Supports nerve function.Omega-3 prescription ethyl esters (if triglycerides high and clinician deems useful)
Anti-inflammatory lipid modulation.Inhaled baclofen or intrathecal baclofen (expert centers only)
For refractory spasticity; intrathecal pumps are surgical (see below). Abrupt withdrawal is dangerous. FDA Access Data
Important: Items are general symptom-relief tools used widely in rehabilitation medicine—not BTS-specific approvals. The FDA labels I cited (baclofen, tizanidine, duloxetine, metoprolol, gabapentin) document their approved indications and safety characteristics; clinical teams decide case-by-case how/if they fit an individual with BTS. FDA Access Data+4FDA Access Data+4FDA Access Data+4
Dietary “molecular” supplements
Use only for documented deficiency or clear clinical rationale.
Vitamin D3 – Supports bone mineralization; typical maintenance 600–1000 IU/day in children (higher if deficient per labs). Helps calcium absorption; low D is linked to weak bones and falls.
Calcium – Builds bone; dose individualized (often 500–1000 mg/day total dietary + supplement). Works by providing the mineral matrix for bones.
Iron – Treat iron-deficiency anemia; ferrous salts commonly 2–3 mg/kg elemental iron/day in children. Restores hemoglobin and oxygen delivery.
Vitamin B12 – For deficiency impacting nerves; oral 1000 mcg/day or periodic injections. Re-methylates homocysteine and supports myelin.
Folate – 400–800 mcg/day if low; vital for DNA synthesis and cell division.
Omega-3 fatty acids (EPA/DHA) – 1–2 g/day combined EPA/DHA (adult typical); anti-inflammatory membrane effects and may aid dry-eye symptoms.
Magnesium – 200–400 mg/day (adult) when lab-proven low; stabilizes neuromuscular excitability.
Zinc – Short courses if deficient; supports growth and immune enzyme systems.
Coenzyme Q10 – Sometimes used in optic-nerve or mitochondrial-style support (evidence variable); acts in electron transport and antioxidant cycling.
Lutein/zeaxanthin – Carotenoids pooling in retina; used for ocular health though data for optic atrophy is limited; antioxidant/photoprotective roles.
Immunity-booster / regenerative / stem-cell” drugs
There are no approved regenerative or stem-cell drugs for Berk–Tabatznik syndrome. Below are honest options typically discussed around immune support and neuro-musculoskeletal recovery:
Vaccines (routine schedule) – Not a “drug” to boost immunity, but the best evidence-based way to prevent infections that derail rehab and schooling. Works by training adaptive immunity.
Nutritional repletion (iron, vitamin D, B12, folate) – Correcting deficiencies measurably improves energy, cognition, and bone strength; “regenerative” in the sense of restoring normal biology.
Intrathecal baclofen (device + drug) – For severe spasticity, programmable pump gives spinal baclofen with fewer systemic effects; improves function and care. Mechanism: GABA_B agonism at spinal level.
Botulinum toxin type A (focal) – Temporarily reduces overactive muscles to allow stretching and functional training, promoting more normal motor patterns.
Erythropoiesis-stimulating agents (only if medically indicated anemia) – Not for BTS per se; can improve activity tolerance by correcting anemia under hematology guidance.
Clinical trial participation (if available) – Experimental neuro-regenerative or gene-agnostic optic-nerve strategies may open in the future; genetics teams can help screen eligibility.
Surgeries / procedures (when and why)
Cervical spine surgery (deformity/instability/cord compression)
Procedure: Decompression and fusion tailored to the anatomy.
Why: Protect the spinal cord, relieve pain, stabilize alignment.Orthopedic hand procedures
Procedure: Tendon balancing, osteotomies, or releases.
Why: Improve pinch/grip or correct angles for function and hygiene.Intrathecal baclofen pump implantation (for severe spasticity)
Procedure: Catheter into intrathecal space connected to programmable pump.
Why: Strong tone reduction with fewer systemic side effects than high-dose oral baclofen.Cochlear implant or middle-ear surgery (selected hearing loss types)
Procedure: Device implantation after audiology/ENT evaluation.
Why: Improve access to sound when hearing aids are insufficient.Cardiac pacemaker/ICD (if cardiology identifies conduction disease/arrhythmia)
Procedure: Device placement with leads to heart.
Why: Prevent syncope or sudden arrhythmic events in proven conduction disorders.
Preventions (practical)
