Genes affected

NPFFR2 (HGNC:4525): (neuropeptide FF receptor 2) This gene encodes a member of a subfamily of G-protein-coupled neuropeptide receptors. This protein is activated by the neuropeptides A-18-amide (NPAF) and F-8-amide (NPFF) and may function in pain modulation and regulation of the opioid system. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2009]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.13).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.986 is higher than 0.05.
