Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1] Associate Editor-in-Chief: Edzel Lorraine Co, DMD, MD[2]
Overview
Adams-Oliver syndrome (AOS) is an autosomal dominant disorder which involves the mutation of six genes, namely the ARHGAP31, DLL4, DOCK6, EOGT, NOTCH1, and RBPJ genes. [1] This disorder has an incidence of 44 per 10 million. Patients who have this condition typically present with some cardiovascular defects, terminal transverse limb defects, neurologic findings, growth deficiency, accessory nipples, cryptorchidism, renal abnormalities, aplasia cutis congenita (ACC), and Poland sequence. [2]
