Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 4P and 3B. PM1PM5BP4_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). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1832W) has been classified as Likely pathogenic.

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. -
