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=-1.12).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00951 (1448/152230) while in subpopulation AFR AF= 0.0334 (1388/41518). AF 95% confidence interval is 0.032. There are 29 homozygotes in gnomad4. There are 694 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 29 AR gene
