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 -13 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.82).

BP6

Variant 22-36284279-C-T is Benign according to our data. Variant chr22-36284279-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 341493.

BS1

Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.0000825 (120/1454752) while in subpopulation NFE AF = 0.000101 (112/1110638). AF 95% confidence interval is 0.0000854. There are 0 homozygotes in GnomAdExome4. There are 62 alleles in the male GnomAdExome4 subpopulation. Median coverage is 35. This position passed quality control check.

BS2

High AC in GnomAd4 at 8 AD gene.
