not provided Uncertain:2
Reported in an individual with nonsyndromic hearing loss in published literature (PMID: 32382995); In silico analysis indicates that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 20301750, 33879153, 17603484, 32382995, 20738327, 18060660, 12955714) -
This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 339 of the WFS1 protein (p.Asp339Asn). 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 autosomal dominant deafness (PMID: 32382995). ClinVar contains an entry for this variant (Variation ID: 215354). 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 WFS1 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. -
Wolfram syndrome 1 Pathogenic:1
Potent mutations in WFS1 gene are associated with Wolfram's syndrome, an autosomal recessive condition, which cause diabetes mellitus, diabetes insipidus, deafness and optic atrophy.However no sufficient evidence is found to ascertain the role of this particular variant rs772392224 in Wolfram's syndrome yet. -
not specified Uncertain:1
The p.Asp339Asn variant in WFS1 has not been previously reported in individuals with hearing loss, but has been identified in 1/66734 European chromosomes by th e Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs77 2392224). Computational prediction tools and conservation analysis do not provid e strong support for or against an impact to the protein. In summary, the clinic al significance of the p.Asp339Asn variant is uncertain. -
