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 Benign. Variant got -19 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), MYH9. . Gene score misZ 3.473 (greater than the threshold 3.09). Trascript score misZ 6.1231 (greater than threshold 3.09). GenCC has associacion of gene with 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=0.010654628).

BP6

Variant 22-36296901-C-T is Benign according to our data. Variant chr22-36296901-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 227606.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000125 (19/152346) while in subpopulation SAS AF= 0.0031 (15/4832). AF 95% confidence interval is 0.00191.
