What are the causes of Adams-Oliver Syndrome?

Mutations in the ARHGAP31, DLL4, DOCK6, EOGT, NOTCH1, or RBPJ gene can cause Adams-Oliver syndrome. Because some affected individuals do not have mutations in one of these genes, it is likely that other genes that have not been identified are also involved in this condition. Each of the known genes plays an important role during embryonic development, and changes in any one of them can impair this tightly controlled process, leading to the signs and symptoms of Adams-Oliver syndrome.

How prevalent is Adams-Oliver Syndrome?

Adams-Oliver syndrome is a rare disorder; its prevalence is unknown.

Is Adams-Oliver Syndrome an inherited disorder?

Adams-Oliver syndrome can have different inheritance patterns. When caused by mutations in the ARHGAP31, DLL4, NOTCH1, or RBPJ gene, the condition is inherited in an autosomal dominant pattern. Autosomal dominant inheritance means that one copy of the altered gene in each cell is sufficient to cause the disorder. The altered gene is typically inherited from an affected parent. Some cases associated with NOTCH1 gene mutations result from new (de novo) mutations in the gene that occur during the formation of reproductive cells (eggs or sperm) or in early embryonic development. These cases occur in people with no history of the disorder in their family.
