Genes affected

GRXCR2 (HGNC:33862): (glutaredoxin and cysteine rich domain containing 2) This gene encodes a protein containing a glutaredoxin domain, which functions in protein S-glutathionylation. A mutation in this gene was found in a family with autoosomal recessive nonsyndromic sensorineural deafness-101. [provided by RefSeq, Jun 2014]

This variant is present in population databases (rs774832434, gnomAD 0.009%). 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 missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This variant has not been reported in the literature in individuals affected with GRXCR2-related conditions. This sequence change replaces tyrosine, which is neutral and polar, with histidine, which is basic and polar, at codon 227 of the GRXCR2 protein (p.Tyr227His). -
