Genes affected

OR2J3 (HGNC:8261): (olfactory receptor family 2 subfamily J member 3) This gene encodes a G-protein-coupled receptor (GPCR) that functions as an olfactory receptor. Olfactory receptors interact with odorant molecules in the nose to initiate a neuronal response that triggers the perception of a smell. The protein encoded by this gene responds to cis-3-hexen-1-ol, which is released by wounded plants, including cut grass. This gene is situated in a cluster of similar olfactory-receptor coding genes on chromosome 6. [provided by RefSeq, May 2013]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=7.120634E-5).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.548 is higher than 0.05.
