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.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0000592 (9/152128) while in subpopulation NFE AF = 0.000132 (9/68006). AF 95% confidence interval is 0.0000681. There are 0 homozygotes in GnomAd4. There are 3 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 9 AD gene.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Glu1350Asp variant in MYH9 has not been previously reported in individuals with hearing loss. It has been identified in 4/66412 European chromosomes by th e Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs37 5955867). Although this variant has been seen in the general population, its fre quency is not high enough to rule out a pathogenic role. Computational predictio n tools and conservation analyses do not provide strong support for or against a n impact to the protein. In summary, the clinical significance of the p.Glu1350A sp variant is uncertain. -
