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.

Submissions by phenotype

not provided Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingInvitaeJul 18, 2022This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 38 of the GRXCR1 protein (p.Pro38Leu). This variant is present in population databases (rs367784906, gnomAD 0.03%). This missense change has been observed in individual(s) with GRXCR1-related conditions (PMID: 20137774). ClinVar contains an entry for this variant (Variation ID: 498748). 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 tolerated. 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. -
