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.

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

c.2500-14A>G variant in intron 20 of MYH9: This variant is not expected to have clinical significance because it does not affect the conserved positions of the 3' splice site and computational tools do not suggest an impact to splicing. In addition, it has also been identified in 0.12% (20/16438) of South Asian chromos omes and in 0.1% (54/65316) of European chromosomes by the Exome Aggregation Con sortium (ExAC, http://exac.broadinstitute.org;dbSNP rs199505086). -

Illumina Laboratory Services, Illumina

Significance:Likely 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 allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
