Adams-Oliver syndrome (AOS) is a rare congenital condition consisting of the association between aplasia cutis congenita, ending transverse limbs defects, and cutis marmorata telangiectatica congenita. AOS can also be associated with extensive anomalies of internal organs including central nervous, cardiopulmonary, gastrointestinal, and genitourinary systems.

Both genetic and sporadic inheritance have been reported in the medical literature; however, in most cases, this syndrome is inherited in an autosomal dominant fashion. Recently, two different truncating mutations in the ARHGAP31 gene were found with a locus on chromosome 3q13.31-q13.33. In addition, an autosomal recessive form is caused by a mutation in the DOCK6 gene on chromosome 19p13.2.
