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, c.671_672insAAA, results in the insertion of 1 amino acid(s) of the GRXCR2 protein (p.Lys224dup), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs760103412, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with GRXCR2-related conditions. ClinVar contains an entry for this variant (Variation ID: 2066670). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -
