Genes affected

MYO7A (HGNC:7606): (myosin VIIA) This gene is a member of the myosin gene family. Myosins are mechanochemical proteins characterized by the presence of a motor domain, an actin-binding domain, a neck domain that interacts with other proteins, and a tail domain that serves as an anchor. This gene encodes an unconventional myosin with a very short tail. Defects in this gene are associated with the mouse shaker-1 phenotype and the human Usher syndrome 1B which are characterized by deafness, reduced vestibular function, and (in human) retinal degeneration. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2008]

Variant classified as Uncertain Significance - Favor Benign. The Ser1135Tyr vari ant in MYO7A has not been previously reported in individuals with hearing loss, but has been identified in 2/8402 of European American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs376688581). Serine (Ser) at position 1135 is not conserved in mammals or evolutionarily dis tant species, raising the possibility that a change at this position may be tole rated. Additional computational prediction tools suggest that this variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, while the clinical significance of the Ser1135Ty r variant is uncertain, these data suggest that it is more likely to be benign. -
