Genes affected

MYO3A (HGNC:7601): (myosin IIIA) The protein encoded by this gene belongs to the myosin superfamily. Myosins are actin-dependent motor proteins and are categorized into conventional myosins (class II) and unconventional myosins (classes I and III through XV) based on their variable C-terminal cargo-binding domains. Class III myosins, such as this one, have a kinase domain N-terminal to the conserved N-terminal motor domains and are expressed in photoreceptors. The protein encoded by this gene plays an important role in hearing in humans. Three different recessive, loss of function mutations in the encoded protein have been shown to cause nonsyndromic progressive hearing loss. Expression of this gene is highly restricted, with the strongest expression in retina and cochlea. [provided by RefSeq, Jul 2008]

p.Ser1616Phe in exon 35 of MYO3A: This variant is not expected to have clinical significance due to a lack of conservation across species, including mammals. Of note, 4 mammals have a phenylalanine (Phe) at this position despite high nearby amino acid conservation. In addition, computational prediction tools do not sug gest a high likelihood of impact to the protein. It has also been identified in 2/61700 European chromosomes by the Exome Aggregation Consortium (ExAC, http://e xac.broadinstitute.org; dbSNP rs752615488). -
