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]

p.Arg1602Gln in exon 35 of MYO7A: This variant is not expect to have clinical si gnificance because it has been identified in 4.4% (377/8484) of East Asian chrom osomes including 7 homozygotes by the Exome Aggregation Consortium (ExAC, http:/ /exac.broadinstitute.org; dbSNP rs139889944). This variant was reported in 2 ind ividuals with Usher syndrome (Liu 1998, Weston 1998). It was reported in trans with p.Leu651Pro in MYO7A of uncertain significance in two affected siblings (Li u 1998) and to be homozygous in another individual (Weston 1998), which is consi stent with its allele frequency in the general population and insufficient to su pport pathogenicity. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
