Summaries for Adams-Oliver Syndrome 5

UniProtKB/Swiss-Prot : 71 Adams-Oliver syndrome 5: A form of Adams-Oliver syndrome, a disorder characterized by the congenital absence of skin (aplasia cutis congenita) in combination with transverse limb defects. Aplasia cutis congenita can be located anywhere on the body, but in the vast majority of the cases, it is present on the posterior parietal region where it is often associated with an underlying defect of the parietal bones. Limb abnormalities are typically limb truncation defects affecting the distal phalanges or entire digits (true ectrodactyly). Only rarely, metatarsals/metacarpals or more proximal limb structures are also affected. Apart from transverse limb defects, syndactyly, most commonly of second and third toes, can also be observed. The clinical features are highly variable and can also include cardiovascular malformations, brain abnormalities and vascular defects such as cutis marmorata and dilated scalp veins.

MalaCards based summary : Adams-Oliver Syndrome 5, is also known as aos5, and has symptoms including brachydactyly, umbilical hernia and splenomegaly. An important gene associated with Adams-Oliver Syndrome 5 is NOTCH1 (Notch 1). Affiliated tissues include bone, brain and heart.

OMIM : 54
Adams-Oliver syndrome (AOS) is a rare developmental disorder defined by the combination of aplasia cutis congenita of the scalp vertex and terminal transverse limb defects (e.g., amputations, syndactyly, brachydactyly, or oligodactyly). In addition, vascular anomalies such as cutis marmorata telangiectatica congenita, pulmonary hypertension, portal hypertension, and retinal hypervascularization are recurrently seen. Congenital heart defects have been estimated to be present in 20% of AOS patients; reported malformations include ventricular septal defects, anomalies of the great arteries and their valves, and tetralogy of Fallot (summary by Stittrich et al., 2014). For a discussion of genetic heterogeneity of Adams-Oliver syndrome, see AOS1 (100300). (616028)
