Stoll–Alembik–Finck syndrome is a very rare genetic condition present from birth. Children have arthrogryposis (stiff joints and contractures in many body areas) and ectodermal changes (teeth missing or small; thin or dry skin; nails that split; reduced sweating, so they overheat easily). Many also have growth delay, spine curvature (kyphoscoliosis), a small head (microcephaly), and mild facial differences. Doctors first reported the pattern in two sisters; since then, only brief mentions exist, and no specific causative gene has been confirmed. Because the literature is small, treatment focuses on early rehabilitation, protecting skin and eyes and mouth, careful dental reconstruction, spine and limb management, temperature safety, and long-term team care. Genetic Rare Disease Center+2Orpha+2
Stoll–Alembik–Finck syndrome is a very rare birth condition first described in the early 1990s. Children are born with stiff joints (arthrogryposis) that limit movement, thin or weak muscles (amyotrophy), and changes in body parts that come from the outer layer of the embryo (ectoderm)—such as the teeth, nails, skin, hair, and sweat glands. Typical findings reported in the medical literature include curved fingers (camptodactyly), joint contractures, few or missing teeth (oligodontia), weak tooth enamel, split or fragile nails, reduced sweating with dry skin, and a tendency to bruise and scar easily. Some children also have slow growth, spinal curve (kyphoscoliosis), small head size (microcephaly), and mild facial differences. Only a handful of cases have been documented, and there have been no detailed new case series since 1992, so our knowledge is limited and based on very small numbers. Orpha+2Genetic Rare Disease Center+2
Because so few cases exist, doctors often diagnose this syndrome clinically—by recognizing the pattern of features—and they also evaluate for other, more common conditions that can look similar. Work-ups usually follow established pathways for arthrogryposis and ectodermal dysplasia, including imaging, skin or dental assessments, and genetic testing when available. Medscape+2Medscape+2

Types
There is no official subtype system for Stoll–Alembik–Finck syndrome due to the very small number of reported patients. However, in practice, clinicians may describe patterns to guide care:
Joint-dominant pattern: contractures and muscle thinning are the most limiting problems; ectodermal signs are milder. This mirrors arthrogryposis-focused management pathways. Medscape+1
Ectodermal-dominant pattern: teeth, nails, sweat glands, skin, or hair problems are more prominent; overheating risk and dental care drive management. NCBI+1
Mixed pattern with spinal involvement: joint and ectodermal features plus kyphoscoliosis that may need orthopedic follow-up. Orpha
Associated-anomalies pattern: same core features with additional minor facial differences or growth delay. Orpha
These descriptive “types” are pragmatic labels, not separate diseases, and are used only to help organize evaluation and support. Orpha
Causes
Because only a few cases exist, the exact cause is unknown. Doctors infer likely mechanisms from what we know about arthrogryposis and ectodermal dysplasias in general. Below are 20 plausible, evidence-informed causes/mechanisms—some genetic, some developmental. In a given child, often more than one factor contributes.
Gene changes affecting ectoderm signaling (EDA/EDAR/EDARADD pathway): these pathways guide development of teeth, hair, nails, and sweat glands. Disruption can produce ectodermal features seen in this syndrome. MedlinePlus
WNT signaling changes (e.g., WNT10A): critical for tooth and ectoderm development; variants can cause missing teeth and enamel problems. MedlinePlus
Embryonic ectoderm–mesoderm interaction defects: the ectoderm communicates with deeper layers to form skin appendages; faulty crosstalk can yield combined ectodermal anomalies. MedlinePlus
Reduced fetal movement (fetal akinesia): less movement in the womb can cause joint contractures typical of arthrogryposis. PM&R KnowledgeNow
Neuromuscular disorders in the fetus: problems in nerves or muscles can limit movement and lead to contractures. PMC
Connective tissue or joint-formation defects: abnormal joint or tendon development can fix joints into bent positions. Medscape
Skeletal development dysplasias: altered bone growth can contribute to short bones and contractures. Medscape
Spinal development differences (kyphoscoliosis): spine curvature may be part of the overall developmental pattern. Orpha
Microcephaly from early brain development issues: small head size is reported and may reflect early CNS development differences. Orpha
Dental development defects (oligodontia, enamel hypoplasia): ectoderm signaling errors during tooth bud formation. NCBI
Nail matrix development defects: produce brittle, split, or longitudinally cracked nails. NCBI
Sweat-gland hypoplasia or absence: leads to heat-intolerance and dry skin. NCBI
Abnormal scar and bruise response: possibly due to skin structure differences in ectodermal tissues. Orpha
Chromosomal microdeletions/duplications (copy-number variants): sometimes found in arthrogryposis/ED workups. Medscape
Single-gene variants not yet identified: ultra-rare conditions may involve genes not yet linked to disease; broader sequencing can sometimes find them. BMJ Journals
Intrauterine constraint (limited space/oligohydramnios): physical restriction of fetal movement can worsen contractures. PMC
Placental insufficiency/hypoxia: can impair muscle and nerve development and reduce fetal motion. AJOG
Maternal illnesses/fevers/medications (nonspecific risk): known contributors to some arthrogryposis patterns, though no specific link is proven for this syndrome. PMC
Prenatal infections affecting movement or development: part of the broad arthrogryposis differential (not proven here, but evaluated). PMC
Multifactorial combination: most likely in such rare patterns—genetic susceptibility plus developmental influences. Medscape
Note: These mechanisms summarize what clinicians look for, not confirmed causes for every child with this exact syndrome. Because no new case series have been published since 1992, causation remains uncertain. Orpha
Symptoms and signs
Joint stiffness from birth (arthrogryposis): elbows, wrists, fingers, hips, knees, or ankles may not fully bend or straighten. This limits movement but is usually non-progressive. PM&R KnowledgeNow
Curved fingers (camptodactyly): one or more fingers are bent and hard to extend. Splinting and therapy often help function. Orpha
Thin muscles (amyotrophy): muscles look small because they did not develop normally around stiff joints. Orpha
Few or missing teeth (oligodontia): baby or adult teeth may be absent; special dental care improves chewing and speech. Orpha+1
Weak tooth enamel: teeth can chip or wear easily and need early dental protection. Orpha
Fragile or split nails: nails may crack along their length or look ridged. Orpha
Dry skin and reduced sweating (hypohidrosis): overheating can happen in warm weather; cooling strategies are important. NCBI
Easy bruising and scarring: skin may mark or scar after minor injury or scratching. Orpha
Spinal curve (kyphoscoliosis): the spine curves sideways and/or forward; sometimes needs bracing or surgery. Orpha
Short stature or slow growth: height and weight may be lower than average over time. Orpha
Small head size (microcephaly): head circumference is below typical ranges for age. Orpha
Mild facial differences: subtle changes in facial shape that do not usually affect function but help doctors recognize the pattern. Orpha
Limited range of motion: joints may not move through a full arc; daily tasks can take more effort. Medscape
Feeding or speech challenges from dental changes: missing teeth or enamel problems can affect chewing and clarity of speech; dental teams can help. UCSF Benioff Children’s Hospitals
Heat intolerance: because sweating is reduced, hot environments can cause overheating; cooling plans are essential. NCBI
Diagnostic tests
A) Physical examination
Full musculoskeletal exam: the doctor looks at how each joint moves, which joints are stiff, and which muscles are thin. This helps confirm arthrogryposis and guides therapy plans. Photos and goniometer measurements are often used to track progress. Medscape
Skin, hair, nails inspection: the team checks for dry skin, reduced sweat, nail fragility, and hair patterns to support the ectodermal dysplasia component. NCBI
Dental exam (pediatric dentistry): counts missing teeth, checks enamel quality, bite alignment, and plans protective treatments or prosthetics if needed. UCSF Benioff Children’s Hospitals
Growth and head-size charting: measures height, weight, and head circumference over time to assess growth delay and microcephaly. Orpha
Spine assessment: looks for kyphoscoliosis using posture tests and forward-bend exams; may trigger imaging and orthopedic referral. Orpha
B) Manual/bedside tests
Range-of-motion (ROM) measurement: simple bedside goniometry records how far joints can bend or straighten and tracks therapy results. Medscape
Functional strength testing: age-appropriate manual muscle tests (e.g., against gravity) help understand muscle involvement. Medscape
Minor’s starch–iodine sweat test: iodine and starch are applied to the skin; areas that sweat turn dark, revealing reduced or absent sweating. Lippincott Journals
Thermoregulation observation: supervised play or mild heat exposure with temperature checks helps identify heat intolerance safely. (Used cautiously.) NCBI
Feeding/speech screen: bedside look at chewing and articulation when teeth are missing; informs referral to speech-language and dental teams. UCSF Benioff Children’s Hospitals
C) Laboratory and pathological tests
Skin biopsy (sweat glands): a tiny skin sample—often from the palm or hypothenar area—can show reduced or absent eccrine glands, supporting ectodermal dysplasia. Medscape
Genetic testing panel (ED/arthrogryposis genes): next-generation sequencing or chromosomal microarray can look for gene changes or copy-number variants that match the child’s features. Yield varies because the specific gene for this eponym is unknown. Medscape+1
Targeted gene testing (e.g., EDA/EDAR/WNT10A) when phenotype suggests it: chosen if the dental, sweat, and hair findings point to classic ED pathways. MedlinePlus
Basic metabolic and neuromuscular labs (as needed): CK, lactate, thyroid, and other screens may be used to rule out more common mimics of arthrogryposis. Medscape
Dental radiographs with enamel assessment reports: while “lab” in nature for dentists, they document enamel density and tooth buds. UCSF Benioff Children’s Hospitals
D) Electrodiagnostic tests
Nerve conduction studies (NCS): check how quickly nerves carry signals; helps decide if a neuropathy contributes to limited fetal or infant movement. Medscape
Electromyography (EMG): measures muscle electrical activity to look for myopathy (muscle disease) patterns that can cause contractures. Medscape
E) Imaging tests
Skeletal X-rays: show bone shape, joint alignment, fused bones, extra or missing small wrist/ankle bones, and scoliosis/ankylosis—key in arthrogryposis. Medscape
Spine radiographs: measure the angle of kyphoscoliosis to plan bracing or surgery if needed. Medscape
Brain MRI (selected cases): for microcephaly or developmental concerns; assesses brain structure. Medscape
Muscle MRI or CT (selected cases): evaluates muscle bulk hidden by contractures; can show fatty replacement or hypoplasia. Medscape
Dental panoramic X-ray (OPG): counts tooth buds and adult teeth, maps missing teeth, and guides dental treatment timing. UCSF Benioff Children’s Hospitals
Hand/foot detailed radiographs: look for camptodactyly architecture and carpal/tarsal anomalies that affect therapy choices. Medscape
Prenatal ultrasound (if evaluated before birth): can detect reduced movement and fixed limb positions (arthrogryposis) and associated findings. PMC+1
Echocardiogram or renal ultrasound (as indicated): used selectively if physical exam suggests organ involvement, since “other anomalies” vary. Medscape

FAQs
1) Is there a known gene for Stoll–Alembik–Finck syndrome?
Not yet. The entity was described clinically in the early 1990s; no definitive causative gene has been established, and no modern case series have updated it. Genetic Rare Disease Center+1
2) How is it diagnosed today?
Clinicians recognize the pattern (arthrogryposis + ectodermal changes + other anomalies), exclude look-alikes, and often use broad genetic testing panels for skeletal dysplasias/arthrogryposis to rule in/out other conditions. GeneDx
3) Is it progressive?
The underlying pattern is congenital; joints can stiffen as the child grows if stretching and bracing lapse, and spinal curves may progress—hence ongoing rehab and orthopedic follow-up. JPOSNA+1
4) What’s the outlook?
Function improves with early, consistent therapy, splints, and timely orthopedic/dental care; heat-safety and skin/dental routines are key to quality of life. PMC+1
5) Can therapy start in infancy?
Yes—early range-of-motion and gentle positioning/splinting are standard in arthrogryposis care and help prevent secondary contractures. PMC
6) Why is heat a big issue?
Reduced sweating (hypohidrosis) impairs cooling; children can overheat quickly without planned hydration, shade, and cooling aids. Global Genes
7) What about dry eyes?
Start with preservative-free artificial tears and environmental measures; ophthalmology may add anti-inflammatory drops if needed. AAO
8) And dry mouth?
Frequent sips, saliva substitutes, xylitol-based products, and high-fluoride care come first; pilocarpine/cevimeline are specialist options when appropriate. Mayo Clinic+1
9) Are dental implants possible?
Yes, typically after growth; before that, removable prostheses and orthodontics are used to support function and appearance. Ectodermal Dysplasias Foundation
10) Which pain medicine is safest?
Acetaminophen is often first-line; ibuprofen can help if no contraindication. Doses must follow trusted pediatric/adult references. PMC+1
11) Any special physical-education advice?
Adaptive PE, heat-safety breaks, and posture/core work are helpful; avoid overheating and respect brace wear schedules. BioMed Central
12) When is spine surgery considered?
For curves that progress or impair function or lung growth; decisions are individualized by pediatric spine teams. PMC
13) Should everyone take vitamin D or calcium?
Meet age-based needs, preferably through diet; supplement only when there’s an indication—routine screening/supplementation in healthy people is not broadly recommended by the latest Endocrine Society guideline. Endocrine Society
14) Are stem-cell therapies used?
No established role for this syndrome; avoid unproven offerings outside clinical trials. JPOSNA
15) What does a “team” look like?
Rehab medicine/physiotherapy, orthopedics, pediatric dentistry/prosthodontics/orthodontics, dermatology, ophthalmology, genetics, nutrition, and psychology—meeting periodically to stage care. JPOSNA
