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 made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

PP2

Missense variant in the MYH9 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 43 curated pathogenic missense variants (we use a threshold of 10). The gene has 84 curated benign missense variants. Gene score misZ: 3.473 (above the threshold of 3.09). Trascript score misZ: 6.1231 (above the threshold of 3.09). GenCC associations: The gene is linked to May-Hegglin anomaly, autosomal dominant nonsyndromic hearing loss, macrothrombocytopenia and granulocyte inclusions with or without nephritis or sensorineural hearing loss, autosomal dominant nonsyndromic hearing loss 17.

BP4

Computational evidence support a benign effect (MetaRNN=0.15244088).

BS2

High AC in GnomAdExome4 at 12 AD gene.
