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.Arg181His in exon 7 of MYO3A: This variant is not expected to have clinical si gnificance due to a lack of conservation across species, including mammals. Of n ote, 3 mammals (Pacific walrus, elephant, platypus) has a histidine (His) at thi s position despite high nearby amino acid conservation. In addition, computation al prediction tools do not suggest a high likelihood of impact to the protein. I t has been identified in 3/30782 South Asian and in 4/111692 European chromosome s by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs574220416). -
