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

GRXCR1-related disorder Pathogenic:1
Likely pathogenic, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesJun 03, 2024The GRXCR1 c.169delG variant is predicted to result in a frameshift and premature protein termination (p.Asp57Ilefs*10). To our knowledge, this variant has not been reported in the literature or in a large population database, indicating this variant is rare. Frameshift variants in GRXCR1 are expected to be pathogenic. This variant is interpreted as likely pathogenic. -
