Genes affected

FAAH2 (HGNC:26440): (fatty acid amide hydrolase 2) This gene encodes a fatty acid amide hydrolase that shares a conserved protein motif with the amidase signature family of enzymes. The encoded enzyme is able to catalyze the hydrolysis of a broad range of bioactive lipids, including those from the three main classes of fatty acid amides; N-acylethanolamines, fatty acid primary amides and N-acyl amino acids. This enzyme has a preference for monounsaturated acyl chains as a substrate. Alternate splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2017]

Nov 23, 2024

The c.110C>T (p.A37V) alteration is located in exon 1 (coding exon 1) of the FAAH2 gene. This alteration results from a C to T substitution at nucleotide position 110, causing the alanine (A) at amino acid position 37 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
