Variant summary: USH2A c.7685T>C (p.Val2562Ala) results in a non-conservative amino acid change located in the Fibronectin type III domain (IPR003961) of the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0065 in 251140 control chromosomes, predominantly at a frequency of 0.0095 within the Non-Finnish European subpopulation in the gnomAD database, including 12 homozygotes. This frequency is close to that estimated for a pathogenic variant in USH2A causing Usher Syndrome (0.0065 vs 0.011), supporting a neutral outcome. Although reported frequently in the literature, to our knowledge, no occurrence of c.7685T>C in individuals affected with Usher Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. At-least one report listed this variant along with two other pathogenic alleles in an individual with Usher syndrome, supporting a benign outcome (example, Hagag_2020). Five clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign. Based on the evidence outlined above, the variant was classified as benign.

Val2562Ala in exon 41 of USH2A: This variant has been reported in nine individua ls with a clinical diagnosis of Usher Syndrome types 1, 2 or 3 (Dreyer 2008, Jai jo 2009). However, several of these individuals already had other explanations f or their Usher syndrome (Jaijo 2009). In addition, this amino acid is not highly conserved acroos evolution, with the mouse and rat having an alanine at positio n 2562. In addition, this variant is listed in dbSNP (rs56385601 - no frequency data available) and has been identified in 6/278 (2.2%) probands tested by our l aboratory, none of whom had a variant on their second USH2A allele. In summary, this variant meets our criteria to be classified as benign. (less)

This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
