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.

MYH9 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: No computational evidence supports a deleterious effect, but strongly conserved according to phyloP
• PP5: Variant 22-36296899-CGCGATCTGGGCCTGGAGCTCG-C is Pathogenic according to our data. Variant chr22-36296899-CGCGATCTGGGCCTGGAGCTCG-C is described in ClinVar as [Pathogenic]. Clinvar id is 14084.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr22-36296899-CGCGATCTGGGCCTGGAGCTCG-C is described in Lovd as [Pathogenic]. Variant chr22-36296899-CGCGATCTGGGCCTGGAGCTCG-C is described in Lovd as [Pathogenic].
• BP3: Nonframeshift variant in repetitive region in NM_002473.6
