Genes affected

GRXCR1 (HGNC:31673): (glutaredoxin and cysteine rich domain containing 1) This gene is one of 60 loci associated with autosomal-recessive nonsyndromic hearing impairment. This gene encodes a protein which contains GRX-like domains; these domains play a role in the S-glutathionylation of proteins and may be involved in actin organization in hair cells.

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 138 of the GRXCR1 protein (p.Arg138Cys). This variant is present in population databases (rs267606856, gnomAD 0.05%). This missense change has been observed in individual(s) with deafness (PMID: 20137778). ClinVar contains an entry for this variant (Variation ID: 196). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). 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. -
