Description : Hemifacial microsomia is a common birth defect involving first and second branchial
arch derivatives. The phenotype is highly variable. In addition to craniofacial anomalies,
there may be cardiac, vertebral, and central nervous system defects. Most cases are
sporadic, but there are rare familial cases that exhibit autosomal dominant inheritance.
See also hemifacial microsomia with radial defects (141400) and oculoauriculofrontonasal
dysplasia (OAFNS; 601452), which may be part of the OAV spectrum.;
