Congenital scalp defects with distal limb reduction anomalies is a rare birth condition where a baby is born with a missing patch of skin on the scalp (often called aplasia cutis congenita) and with fingers, toes, hands, or feet that are smaller, fused, short, or partly missing (called terminal transverse limb defects). In some babies, blood vessels, heart, or skull bones can also be affected. The condition ranges from mild (small scalp wound and mild toe changes) to severe (large scalp loss with bone involvement and major limb absence). The most common clinical label for this pattern is Adams–Oliver syndrome (AOS), but “AOS” and “congenital scalp defects with distal limb anomalies” are often used together because they describe the same clinical picture.
Adams–Oliver syndrome is a birth condition in which a baby has one or more patches of missing skin on the scalp and also has changes of the hands or feet. The scalp problem is called aplasia cutis congenita. It can be shallow (only skin is missing) or deep (skin and skull bone are partly missing). The limb problem is usually at the ends of the fingers or toes. Digits may be short, fused together, or missing. Some babies also have visible, net-like veins in the skin, heart or blood-vessel problems, or learning and development issues. Doctors diagnose AOS when the scalp defect occurs together with distal limb defects. PMCMedlinePlusDermNet®
Other names
This condition is known by several names in the medical literature. The most common is Adams–Oliver syndrome. You may also see AOS, congenital scalp defects with distal limb reduction, aplasia cutis congenita with terminal transverse limb defects, syndromic aplasia cutis congenita, absence defect of limbs, scalp and skull, and Type 2 aplasia cutis (in the classic aplasia cutis classification system). These names all describe the same core picture: missing scalp skin at birth plus shortening, fusion, or absence of fingers or toes. The words vary because some focus on the skin part, some on the limb part, and some on the genetic syndrome that joins them. DermNet®+1
Types
1) By inheritance (how it runs in families).
There are two main inheritance patterns. Autosomal dominant AOS: a change in one copy of a gene is enough to cause the syndrome; it can be inherited from an affected parent or arise as a new (de novo) change. Autosomal recessive AOS: both copies of a gene are changed; this form is more likely when parents are related (consanguineous). MedlinePlusPMC
2) By gene (molecular subtypes).
Pathogenic variants have been confirmed in six genes that control early blood-vessel and tissue development: ARHGAP31, NOTCH1, DLL4, RBPJ (typically autosomal dominant) and DOCK6, EOGT (typically autosomal recessive). These genes sit in two key pathways: Notch signaling (NOTCH1, DLL4, RBPJ, EOGT) and Rho-GTPase/cytoskeletal control (ARHGAP31, DOCK6). Different genes can produce similar outward features. PMCMedlinePlus
3) By clinical pattern (what features are most prominent).
Doctors sometimes group patients by the main problems they have: classic AOS (scalp + distal limb defects), AOS with vascular/cardiac features (e.g., cutis marmorata telangiectatica congenita, pulmonary hypertension, congenital heart defects), and AOS with neurological involvement (developmental delay, structural brain findings, seizures). These are useful clinical “buckets,” not strict categories. DermNet®MedlinePlus
Causes
ARHGAP31 gene variants. Changes in this gene disturb Rho-GTPase control of the cell skeleton during limb and scalp development. PMC
NOTCH1 gene variants. Faulty Notch signaling alters blood-vessel formation and tissue patterning. openaccess.sgul.ac.ukPMC
DLL4 gene variants. DLL4 is a Notch ligand critical for arterial development; variants can produce the AOS picture. PMC
RBPJ gene variants. RBPJ transmits Notch signals inside the nucleus; altered signals can impair scalp and limb development. PMC
DOCK6 gene variants. DOCK6 helps activate Rac1/Cdc42; loss-of-function disturbs the actin cytoskeleton in developing limbs/skin. PMC
EOGT gene variants. EOGT adds O-GlcNAc to Notch pathway proteins; failure of this glycosylation disrupts Notch signaling. PMC
Autosomal dominant inheritance. A parent with an AOS variant can pass it to a child (50% chance each pregnancy). MedlinePlus
Autosomal recessive inheritance. Two carrier parents can have an affected child when both pass on the altered gene. PMC
De novo (new) mutation. A harmful change can arise for the first time in the child, even if parents are unaffected. MedlinePlus
Notch pathway disruption (general). When Notch signals fail, blood vessels and tissue boundaries form abnormally. openaccess.sgul.ac.uk
Rho-GTPase/cytoskeletal pathway disruption (general). Disturbed Rac1/Cdc42 activity impairs cell movement and shape in the limb bud and scalp. IJSTR
Abnormal embryonic scalp perfusion. Reduced blood supply to scalp skin/bone may contribute to aplasia cutis in AOS. Orpha
Abnormal perfusion of limb buds. Poor early blood-vessel patterning can lead to terminal limb reduction. PMC
Unknown genetic causes. Some patients have classic AOS but no change is found in the six known genes, suggesting other genes. MedlinePlus
Variable expressivity. The same genetic change can look mild in one family member and severe in another (a cause of clinical variation). MedlinePlus
Reduced penetrance. Some people with a pathogenic variant may show few or no obvious features, complicating family patterns. MedlinePlus
Mosaicism. A new mutation in early embryo cells can affect only some tissues, changing which areas show defects. (Inferred from rare-disease genetics principles; used clinically to explain patchy findings.) PMC
Gene–environment interaction. The same variant may cause different severity depending on other modifiers and pregnancy factors. (General inference supported by variable expressivity across cohorts.) PMC
Aplasia cutis pathway overlaps. ACC itself has multiple etiologies; AOS represents the “ACC with limb anomalies” subgroup (Frieden Group 2). DermNet®
As-yet-unidentified pathway defects. Large cohort studies still find only ~30% with a molecular diagnosis, pointing to undiscovered mechanisms. PubMed
Symptoms and signs
Patch(es) of missing scalp skin at birth. Size ranges from small hairless spots to larger defects; deep ones can involve skull bone. DermNet®
Hairless scar on the scalp as it heals. Shallow lesions often heal with a smooth, hair-free scar. DermNet®
Skull bone defect under the skin gap. Sometimes the skull is thin or partly absent under the lesion. DermNet®
Shortened fingers or toes (brachydactyly). Digits may be small or stubby. PMC
Missing fingers or toes (oligodactyly). Some digits may be absent at birth. PMC
Fused fingers or toes (syndactyly). Soft-tissue fusion can occur. PMC
Nail underdevelopment (nail hypoplasia). Nails can be very small or absent. PMC
Net-like purple-red skin pattern (cutis marmorata telangiectatica congenita). This shows blood-vessel anomalies in the skin. DermNet®
Visible dilated scalp veins. Prominent superficial veins may be seen. PMC
Congenital heart defects. Heart structure problems can occur in some babies. PMCMedlinePlus
Pulmonary hypertension. High pressure in lung blood vessels may complicate severe cases. MedlinePlus
Developmental delay or learning difficulties. Some children have delays or brain structure differences. MedlinePlus
Seizures (in some). Neurologic involvement can include seizures. MedlinePlus
Eye problems. Reported issues include glaucoma and retinal detachment in some patients. PubMed
Feeding problems and poor weight gain in infancy (some cases). These can occur when defects are extensive or when other systems are involved. PMC
Diagnostic tests
A) Physical examination (bedside inspection and palpation)
Full newborn exam of the scalp lesion. The doctor measures the size, checks depth, looks for signs of infection, and feels the skull edges. This tells whether simple wound care or urgent protection/surgery is needed. DermNet®
Limb examination (hands and feet). The clinician counts digits; looks for short, absent, or fused toes/fingers; and checks nails. This confirms the “distal limb reduction” part of the syndrome. PMC
Skin vascular pattern check. Looking for a net-like marbled skin (cutis marmorata telangiectatica congenita) and for enlarged scalp veins helps identify vascular involvement. DermNet®
Cardiorespiratory exam. Listening for murmurs, checking breathing, and oxygenation can catch heart and pulmonary problems early. MedlinePlus
Neurologic and growth assessment. Head size, tone, and primitive reflexes are checked to screen for brain involvement or developmental delay. MedlinePlus
B) Manual/functional bedside tests
Capillary refill and limb perfusion check. Pressing and releasing the skin of digits tests blood flow to the distal limbs—important when reduction defects or vascular anomalies exist (quick refill is reassuring). (Clinical standard for peripheral perfusion in neonates.)
Gentle sterile probing of the scalp defect (when indicated). A careful bedside check helps determine if bone is exposed under a thin membrane, guiding imaging/surgical decisions. DermNet®
Range-of-motion and grasp/plantar response assessment. Simple functional checks help plan therapy and devices for daily function. (Standard neonatal/orthopedic assessment.)
Developmental screens in infancy. Early screens (e.g., motor milestones) direct referrals to early-intervention services when needed. MedlinePlus
C) Laboratory and pathological tests
Complete blood count (CBC). Baseline blood counts are useful if there is bleeding from the lesion or planned surgery; they also help track infection. (Standard neonatal practice for significant wounds.)
Inflammation markers (CRP/ESR). These help monitor for secondary infection of the scalp defect. (Standard wound-care practice.)
Wound culture (when infected). Culture guides antibiotic choice if a lesion looks infected. DermNet®
Genetic testing panel for AOS. Next-generation sequencing of ARHGAP31, NOTCH1, DLL4, RBPJ, DOCK6, EOGT (and related genes) can confirm the diagnosis and clarify inheritance. Yield is substantial but not 100%, so a negative test does not exclude AOS. PMCPubMed
Occasional tissue sampling at lesion edge (rare). When the appearance is atypical or another diagnosis is suspected, a small biopsy may be taken to exclude other causes of congenital skin loss. DermNet®
D) Electrodiagnostic studies
Electrocardiogram (ECG). Screens heart rhythm and conduction if a murmur, cyanosis, or heart defect is suspected. Some AOS patients have cardiac involvement. PMC
Pulse oximetry monitoring. Continuous oxygen-saturation checks help detect unseen cardiorespiratory problems and are routine in at-risk newborns. (Standard neonatal practice; used when pulmonary hypertension is a risk.) MedlinePlus
Electroencephalogram (EEG) if seizures occur. Records brain electrical activity to evaluate and guide seizure care. MedlinePlus
E) Imaging tests
Cranial ultrasound or brain MRI. Looks for skull defects under the scalp lesion and for brain structure differences. MRI is best when deep defects are suspected. DermNet®
Echocardiography. Ultrasound of the heart checks for congenital heart defects and pulmonary hypertension, which can occur in AOS. MedlinePlus
Skeletal radiographs of skull and limbs. X-rays document bone loss or absence in digits and skull and help plan surgery or prosthetics. (Orthopedic/radiology standard for limb reduction defects.) PMC

Frequently Asked Questions
Is this the same as Adams–Oliver syndrome?
Yes. “Congenital scalp defects with distal limb reduction anomalies” describes the core features of Adams–Oliver syndrome.Did I do something to cause it?
No. Most cases are due to genetic changes or new variants that are not under parental control.Can it be detected before birth?
Sometimes. Detailed ultrasound or fetal MRI may show limb differences or scalp/skull issues in later pregnancy, but mild cases can be missed.Is there a cure?
There is no single medicine to cure the condition. Care focuses on safe wound closure, preventing complications, improving limb function, and supporting development.Will my child have normal brain development?
Many children develop well, especially when scalp defects are small and there are no brain/skull complications. Early therapy and monitoring help.Can the scalp heal without surgery?
Small defects often heal with careful dressings. Larger or deep defects may need surgical coverage.Are the limb differences painful?
Not usually by themselves, but some children develop stiffness, fatigue, or sensitivity. Therapy and adaptive tools help a lot.Will my child be able to write, play, and do sports?
Yes, with adaptive strategies and devices as needed. Many children participate fully in school and play.Is the condition inherited?
It can be. Some families have autosomal dominant inheritance; others are recessive; some are new (de novo). Genetic counseling explains your family’s pattern.What specialists are involved?
Neonatology, plastic/craniofacial surgery, dermatology, orthopedics/hand surgery, cardiology, genetics, neurosurgery (if skull/bone exposed), PT/OT, psychology, and primary care.How do we prevent infection at the scalp site?
Gentle cleansing, moist non-adherent dressings, clean hands, and quick evaluation of any redness, drainage, fever, or foul smell.Are “immune boosters” needed?
No special boosters are required. The most effective “booster” is following the routine vaccination schedule and good nutrition/sleep.Will my child need a helmet?
Sometimes, especially when starting to crawl/walk and if the scalp area is fragile. The team will advise if and when it’s helpful.Could heart problems be part of this?
Yes, some children have heart defects or vessel issues. Screening echocardiograms and follow-ups catch and treat those early.What is the long-term outlook?
With timely wound management, therapy, and tailored surgeries, many children achieve excellent function and quality of life. Outlook depends on how severe the scalp, limb, and any heart/vessel issues are.
