Adams-Oliver syndrome (AOS) is a rare condition defined by the combination of aplasia cutis congenita (ACC), characterized by scalp and skull lesions, and transverse limb abnormalities. Mutations in ARHGAP31 (AOS1), RBPJ (AOS3) and NOTCH1 (AOS5) cause autosomal dominant AOS. Mutations in DOCK6 (AOS2) and EOGT (AOS4) result in autosomal recessive AOS.
