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]

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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with GRXCR2-related conditions. This variant is present in population databases (rs763644996, gnomAD 0.0009%). This sequence change replaces phenylalanine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 223 of the GRXCR2 protein (p.Phe223Leu). -
