Description : Adams-Oliver syndrome (AOS) is characterized by the congenital absence of skin, known as 'aplasia cutis congenita,' usually limited to the scalp vertex, and transverse limb defects. The clinical features are highly variable and can also include vascular defects, congenital cardiac malformations, and other abnormalities (summary by Verdyck et al., 2006). - Genetic Heterogeneity of Adams-Oliver Syndrome Another autosomal dominant form of Adams-Oliver syndrome (AOS3; 614814) is caused by mutation in the RBPJ gene (147183) on chromosome 4p15. Autosomal recessive forms of Adams-Oliver syndrome include AOS2 (614219), caused by mutation in the DOCK6 gene (614194) on chromosome 19p13.2, and AOS4 (615297), caused by mutation in the EOGT gene (614789) on chromosome 3p14.;

Inheritance : Autosomal dominant;

Molecular basis : Caused by mutation in the Rho GTPase-activating protein 31 gene (ARHGAP31, 610911.0001);

Prefixed ID : #100300;
