<unk>  is a rare condition that is genetically inherited in an autosomal dominant manner. Although there is no specific biological mechanism for<unk> , what is recognized is that there is a genetic mutation, known as haploinsufficiency, that occurs in the fibroblast growth factor 3 (FGF3) gene (11q13). This is the alleged cause of the physical abnormalities and symptoms associated with<unk> . Although in individuals with signs of ocular coloboma, a microdeletion in the Fas-associated death domain (FADD) gene (11q13.3) was also found to be responsible. There is variable penetrance and variable gene expression within these genetic mutations. Individuals with sensorineural hearing loss are believed to have a local lesion in the auditory segment of the inner ear, known as the cochlea. The biological mechanism for this is currently unknown as well.
