Genes affected
USH2A (HGNC:12601): (usherin) This gene encodes a protein that contains laminin EGF motifs, a pentaxin domain, and many fibronectin type III motifs. The protein is found in the basement membrane, and may be important in development and homeostasis of the inner ear and retina. Mutations within this gene have been associated with Usher syndrome type IIa and retinitis pigmentosa. Multiple transcript variants encoding different isoforms have been found for this gene.

Variant summary: USH2A c.11404G>A (p.Glu3802Lys) results in a conservative amino acid change located in the Fibronectin type III domain (IPR003961) of the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0025 in 249888 control chromosomes in the gnomAD database, including 3 homozygotes. This frequency is not significantly higher than estimated for a pathogenic variant in USH2A causing Usher Syndrome (0.0025 vs 0.011), allowing no conclusion about variant significance. To our knowledge, no penetrant association of c.11404G>A in individuals affected with Usher Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Three 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. -

Significance:Benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

p.Glu3802Lys in exon 59 of USH2A: This variant is not expected to have clinical significance because it has been identified in 1.3% (280/21974) of Finnish chrom osomes including 2 homozygotes by the Genome Aggregation Database (gnomAD, http: //gnomad.broadinstitute.org; dbSNP rs147900972). In addition, computational anal yses do not suggest a high likelihood of clinical significance primarily based u pon a lack of conservation across species including mammals. Of note, orangutan, rat, mouse, dog and cow have a lysine at this position despite high nearby amin o acid conservation. -
