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]

The c.563A>G (p.Y188C) alteration is located in exon 3 (coding exon 2) of the NAPEPLD gene. This alteration results from a A to G substitution at nucleotide position 563, causing the tyrosine (Y) at amino acid position 188 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
