Illumina Laboratory Services, Illumina RCV001167576 SCV001330094 uncertain significance Usher syndrome type 2D 2018-01-13 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.

Invitae RCV001295889 SCV001484840 uncertain significance not provided 2022-02-09 criteria provided, single submitter clinical testing 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. ClinVar contains an entry for this variant (Variation ID: 913776). This variant has not been reported in the literature in individuals affected with WHRN-related conditions. This variant is present in population databases (rs763014940, gnomAD 0.02%). This sequence change affects codon 108 of the WHRN mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the WHRN protein.
