Genes affected

MYO15A (HGNC:7594): (myosin XVA) This gene encodes an unconventional myosin. This protein differs from other myosins in that it has a long N-terminal extension preceding the conserved motor domain. Studies in mice suggest that this protein is necessary for actin organization in the hair cells of the cochlea. Mutations in this gene have been associated with profound, congenital, neurosensory, nonsyndromal deafness. This gene is located within the Smith-Magenis syndrome region on chromosome 17. Read-through transcripts containing an upstream gene and this gene have been identified, but they are not thought to encode a fusion protein. Several alternatively spliced transcript variants have been described, but their full length sequences have not been determined. [provided by RefSeq, Jul 2008]

p.Arg1129Gln in exon 2 of MYO15A: This variant is not expected to have clinical significance due to a lack of conservation across species, including mammals. Of note, 12 mammals have a glutamine (Gln) at this position despite high nearby am ino acid conservation. In addition, computational prediction tools do not sugges t a high likelihood of impact to the protein. It has also been identified in 1/5 468 chromosomes of unspecified ethnicity and 1/15239 African chromosomes by the Genome Aggregation Database (gnomAD, http://gnomAD.broadinstitute.org). -
