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]

The p.Thr1013Ile variant in MYO7A has not been previously reported in individual s with hearing loss or Usher syndrome, but has been identified in 6/9716 of Afri can chromosomes and by the Exome Aggregation Consortium (ExAC, http://exac.broad institute.org; dbSNP rs369539923). Although this variant has been seen in the ge neral population, its frequency is not high enough to rule out a pathogenic role . Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summary, the clinical signi ficance of the p.Thr1013Ile variant is uncertain. -

The c.3038C>T (p.T1013I) alteration is located in exon 24 (coding exon 23) of the MYO7A gene. This alteration results from a C to T substitution at nucleotide position 3038, causing the threonine (T) at amino acid position 1013 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
