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

Verdict is Benign. Variant got -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.66).
• BP6: Variant 22-36285885-G-A is Benign according to our data. Variant chr22-36285885-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 504624.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-0.075 with no splicing effect.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0000592 (9/151988) while in subpopulation NFE AF= 0.000132 (9/67988). AF 95% confidence interval is 0.0000681. There are 0 homozygotes in gnomad4. There are 3 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High AC in GnomAd at 9 AD gene.

p.Ile1710Ile in Exon 36 of MYH9: This variant is not expected to have clinical s ignificance because it does not alter an amino acid residue, is not located with in the splice consensus sequence and splice prediction algorithms do not predict a newly created splice site. This variant has been identified in 10/126528 of E uropean chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.br oadinstitute.org/; dbSNP rs150198935). -
