Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 4P and 3B. PM1PM2BP4_ModerateBP6

The NM_000260.4(MYO7A):c.5495G>A(p.Arg1832Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000621 in 1,578,034 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. R1832R) has been classified as Likely benign.

Genes affected

MYO7A (HGNC:7606): (myosin VIIA) This gene is a member of the myosin gene family. Myosins are mechanochemical proteins characterized by the presence of a motor domain, an actin-binding domain, a neck domain that interacts with other proteins, and a tail domain that serves as an anchor. This gene encodes an unconventional myosin with a very short tail. Defects in this gene are associated with the mouse shaker-1 phenotype and the human Usher syndrome 1B which are characterized by deafness, reduced vestibular function, and (in human) retinal degeneration. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2008]

The Arg1832Gln variant in MYO7A has not been previously reported in individuals with hearing loss, but has been identified in 0.07% (3/4216) of African American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu /EVS/). Computational analyses (biochemical amino acid properties, conservation , AlignGVGD, PolyPhen2, and SIFT) do not provide strong support for or against a n impact to the protein. In summary, the clinical significance of the Arg1832Gln variant is uncertain. -
