Genes affected

MYH9 (HGNC:7579): (myosin heavy chain 9) This gene encodes a conventional non-muscle myosin; this protein should not be confused with the unconventional myosin-9a or 9b (MYO9A or MYO9B). The encoded protein is a myosin IIA heavy chain that contains an IQ domain and a myosin head-like domain which is involved in several important functions, including cytokinesis, cell motility and maintenance of cell shape. Defects in this gene have been associated with non-syndromic sensorineural deafness autosomal dominant type 17, Epstein syndrome, Alport syndrome with macrothrombocytopenia, Sebastian syndrome, Fechtner syndrome and macrothrombocytopenia with progressive sensorineural deafness.

Review Status:no assertion criteria provided

Collection Method:clinical testing

The MYH9 c.32A>G variant is predicted to result in the amino acid substitution p.Tyr11Cys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.028% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Illumina Laboratory Services, Illumina

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Tyr11Cys variant in MYH9 has not been previously reported in individuals w ith hearing loss or MYH9-related disorders. This variant has been identified in 15/66420 European chromosomes by the Exome Aggregation Consortium (ExAC, http:/ /exac.broadinstitute.org; dbSNP rs201415443); however, this frequency is not hig h enough to rule out a pathogenic role. Computational prediction tools and conse rvation analyses do not provide strong support for or against an impact to the p rotein. In summary, the clinical significance of this variant is uncertain. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.32A>G (p.Y11C) alteration is located in exon 2 (coding exon 1) of the MYH9 gene. This alteration results from a A to G substitution at nucleotide position 32, causing the tyrosine (Y) at amino acid position 11 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
