Variant summary

Our verdict is Benign. Variant got -7 ACMG points: 2P and 9B. PP2PP3BP6BS1BS2

The ENST00000216181.11(MYH9):c.5107C>T(p.Arg1703Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000992 in 1,612,426 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1703Q) has been classified as Uncertain significance.

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.

The Arg1703Trp variant in MYH9 has not been previously reported in individuals w ith hearing loss or in large population studies. Computational analyses (biochem ical amino acid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) sugges t that the Arg1703Trp variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, additional data i s needed to determine the clinical significance of this variant. -
