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 specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineApr 29, 2016This p.Phe120Leu variant in GRXCR1 has not been previously reported in individua ls with hearing loss, but was identified in 1/66030 European chromosomes and in 1/9592 African chromosomes by the Exome Aggregation Consortium (ExAC, http://exa c.broadinstitute.org; dbSNP rs529420082). Although this variant has been seen i n the general population, its frequency is not high enough to rule out a pathoge nic role. Computational prediction tools and conservation analysis do not provi de strong support for or against an impact to the protein. In summary, the clini cal significance of the p.Phe120Leu variant is uncertain. -
Autosomal recessive nonsyndromic hearing loss 25 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaJan 13, 2018This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
