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

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.77T>C (p.L26P) alteration is located in exon 1 (coding exon 1) of the OR2J3 gene. This alteration results from a T to C substitution at nucleotide position 77, causing the leucine (L) at amino acid position 26 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
