chr4-42893456-G-A

Variant summary

Our verdict is Benign. Variant got -18 ACMG points: 2P and 20B. PS1_ModerateBP4_StrongBP6_Very_StrongBS1BS2

The NM_001080476.3(GRXCR1):​c.190G>A​(p.Gly64Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000395 in 1,613,890 control chromosomes in the GnomAD database, including 9 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin UniProt. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G64D) has been classified as Uncertain significance.

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.
