The variant allele was found at a frequency of 0.0647 in 152,250 control chromosomes in the GnomAD database, including 356 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.065 (356 hom., cov: 33)
• Consequence: NAPEPLD NM_001122838.3 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.347

Genes affected

NAPEPLD (HGNC:21683): (N-acyl phosphatidylethanolamine phospholipase D) NAPEPLD is a phospholipase D type enzyme that catalyzes the release of N-acylethanolamine (NAE) from N-acyl-phosphatidylethanolamine (NAPE) in the second step of the biosynthesis of N-acylethanolamine (Okamoto et al., 2004 [PubMed 14634025]).[supplied by OMIM, Oct 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.0763 is higher than 0.05.
