Summaries for Adams-Oliver Syndrome 2

UniProtKB/Swiss-Prot : 76 Adams-Oliver syndrome 2: 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 2, also known as aos2, is related to adams-oliver syndrome and oliver syndrome, and has symptoms including seizures An important gene associated with Adams-Oliver Syndrome 2 is DOCK6 (Dedicator Of Cytokinesis 6). Affiliated tissues include brain, skin and bone, and related phenotypes are macrocephaly and optic atrophy

OMIM : 58 Adams-Oliver syndrome-2 is an autosomal recessive multiple congenital anomaly syndrome characterized by aplasia cutis congenita (ACC) and terminal transverse limb defects, in association with variable involvement of the brain, eyes, and cardiovascular systems (summary by Shaheen et al., 2011). For a discussion of genetic heterogeneity of Adams-Oliver syndrome, see AOS1 (100300). (614219)
