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.
