Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 4P and 12B. PM2PM5BP4_StrongBP6_Very_Strong

The NM_206933.4(USH2A):c.13775A>G(p.Gln4592Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000328 in 1,614,164 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Q4592H) has been classified as Uncertain significance.

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.

p.Gln4592Arg in exon 63 of USH2A: This variant is not expected to have clinical significance due to a lack of conservation across species, including mammals. Of note, over 10 mammals have a Arginine (R) at this position. Additionally, It ha s been identified in 0.14% (16/11566) of Latino chromosomes by the Exome Aggrega tion Consortium (ExAC, http://exac.broadinstitute.org, dbSNP rs201864716). -
