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: Benign. The variant received -12 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.4).
BP6
Variant 22-36326589-C-T is Benign according to our data. Variant chr22-36326589-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 164464.
BP7
Synonymous conserved (PhyloP=-0.196 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000604 (92/152334) while in subpopulation AFR AF = 0.00207 (86/41586). AF 95% confidence interval is 0.00171. There are 0 homozygotes in GnomAd4. There are 44 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
BS2
High AC in GnomAd4 at 92 AD gene.
