Genes affected

GRXCR2 (HGNC:33862): (glutaredoxin and cysteine rich domain containing 2) This gene encodes a protein containing a glutaredoxin domain, which functions in protein S-glutathionylation. A mutation in this gene was found in a family with autoosomal recessive nonsyndromic sensorineural deafness-101. [provided by RefSeq, Jun 2014]

ACMG classification

Verdict is Likely_benign. Variant got -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.32).
• BP7: Synonymous conserved (PhyloP=1.9 with no splicing effect.
