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.

Classification made for transcript

Verdict is Likely_benign. Variant got -2 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.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.759

Variant classified as Uncertain Significance - Favor Benign. The Arg1936Trp vari ant in MYH9 has not been reported in the literature or in large population studi es. The arginine (Arg) residue at position 1936 is not conserved across species , with sloth having a Trp. Although additional information is needed to fully as sess the clinical significance of this variant; the lack of conservation suggest s a more likely benign role. -

Collection Method: clinical testing

This MYH9 missense variant (rs727503281) is rare (<0.1%) in a large population dataset (gnomAD: 8/250532 total alleles; 0.003193%; no homozygotes). It has an entry in ClinVar (Variation ID 164412), but has not ben reported in the literature, to our knowledge. Three bioinformatic tools queried predict that this substitution would be deleterious, and the arginine residue at this position is evolutionarily conserved across all species assessed. We consider the clinical significance of c.5806C>T to be uncertain at this time. -

Significance: Uncertain significance
Review Status: no assertion criteria provided
Collection Method: clinical testing

The MYH9 c.5806C>T variant is predicted to result in the amino acid substitution p.Arg1936Trp. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0098% of alleles in individuals of South Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
