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.

not provided Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpAug 03, 2022This sequence change falls in intron 2 of the GRXCR1 gene. It does not directly change the encoded amino acid sequence of the GRXCR1 protein. This variant is present in population databases (rs606231120, gnomAD 0.002%). This variant has been observed in individual(s) with autosomal recessive deafness (PMID: 20137778). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 193). Studies have shown that this variant is associated with altered splicing resulting in unknown protein product impact (PMID: 20137778). For these reasons, this variant has been classified as Pathogenic. -
