Invitae | RCV001370519 | SCV001567028 | uncertain significance | not provided | 2022-09-01 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 3797 of the USH2A protein (p.Gly3797Arg). This variant also falls at the last nucleotide of exon 58, which is part of the consensus splice site for this exon. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with USH2A-related conditions (Invitae). ClinVar contains an entry for this variant (Variation ID: 1061012). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
