Submissions by phenotype
not specified Uncertain:1
The p.Gly693Arg variant in TECTA has not been previously reported in individuals with hearing loss, but has been identified in 5/66516 of European chromosomes b y the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs200502160). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational predi ction tools and conservation analyses suggest that the p.Gly693Arg variant may i mpact the protein, though this information is not predictive enough to determine pathogenicity. In summary, the clinical significance of the p.Gly693Arg variant is uncertain. -
Autosomal recessive nonsyndromic hearing loss 21 Uncertain:1
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. -
not provided Uncertain:1
This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 693 of the TECTA protein (p.Gly693Arg). This variant is present in population databases (rs200502160, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with TECTA-related conditions. ClinVar contains an entry for this variant (Variation ID: 229293). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt TECTA protein function with a negative predictive value of 95%. 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. -
