Which are the symptoms of Adams-Oliver syndrome?

Adams-Oliver syndrome is a rare congenital disorder primarily characterized by the combination of scalp defects (aplasia cutis congenita) and terminal transverse limb defects. While symptoms vary significantly in severity, the syndrome may also involve cardiovascular, neurological, and ophthalmological complications that require multidisciplinary clinical management.

What are the primary symptoms of Adams-Oliver syndrome?

The hallmark clinical features of Adams-Oliver syndrome involve a spectrum of physical manifestations present at birth. The most characteristic sign is aplasia cutis congenita, which appears as a localized area of missing skin on the scalp, often accompanied by underlying bone defects. This is frequently paired with limb anomalies, which range from mild shortening of fingers or toes (brachydactyly) to the complete absence of hands or feet. Within the DiseaseMaps.org community, 85 people with Adams-Oliver syndrome have shared their experiences, highlighting the vast heterogeneity of these physical presentations.

How does the severity of Adams-Oliver syndrome vary?

The clinical expression of Adams-Oliver syndrome is highly variable, even among members of the same family. Some individuals may only exhibit minor scalp scarring and subtle nail abnormalities, while others may experience severe limb reductions and life-threatening internal complications. Key systemic symptoms that define the more severe end of the spectrum include:

• Cardiovascular issues: Congenital heart defects or pulmonary hypertension.


• Vascular anomalies: Cutis marmorata telangiectatica congenita (a persistent, lace-like skin discoloration).


• Neurological involvement: Structural brain abnormalities, intellectual disability, or seizures.


• Ocular manifestations: Microphthalmia (abnormally small eyes) or cataracts.

When should families seek immediate medical attention?

Because Adams-Oliver syndrome can involve complex vascular and neurological systems, families should be vigilant for specific warning signs. Immediate medical evaluation is required if an infant exhibits signs of respiratory distress, unexplained seizures, or if the scalp lesion shows signs of secondary infection, bleeding, or significant enlargement. Because the scalp defect in Adams-Oliver syndrome can sometimes overlie the sagittal sinus, there is a risk of severe hemorrhage if the area is not managed appropriately by a pediatric surgical team.

How do symptoms change or progress over time?

While the structural limb and scalp defects associated with Adams-Oliver syndrome are typically stable after birth, the secondary impacts of these conditions may evolve. For example, as a child grows, the scalp defect may heal with scarring, but the underlying bone gap may persist, requiring neurosurgical consultation. Furthermore, if cardiovascular or neurological symptoms are present, these require longitudinal monitoring by specialists to manage potential developmental delays or cardiac complications. Quality of life is often most affected by the functional limitations of limb defects and the long-term management of chronic skin or vascular issues.

Next steps

• Consult a clinical geneticist to confirm the diagnosis and discuss potential genetic testing for known causative genes.


• Schedule evaluations with a pediatric cardiologist and a neurologist to screen for internal systemic involvement.


• Connect with the 85 members of the Adams-Oliver syndrome community on DiseaseMaps.org to share experiences and coping strategies.


• Work with a multidisciplinary team, including orthopedic surgeons and dermatologists, to create a long-term care plan.
