Type : Phenotype or locus, molecular basis unknown;
Alternative titles and symbols : Oculoauriculofrontonasal dysplasia;
Description : The OAFNS phenotype combines abnormalities of the morphogenesis of the first and second
branchial arches (microtia/skin tags, epibulbar dermoids, cleft lip/palate, mandibular
hypoplasia, and facial asymmetry) with malformations due to the anomalous development
of the frontonasal eminence and maxillary processes (notched/bifid nasal tip, cleft
lip and/or palate, and encephalocele) (Gabbett et al., 2008).;
