Genes affected
FAAH (HGNC:3553): (fatty acid amide hydrolase) This gene encodes a protein that is responsible for the hydrolysis of a number of primary and secondary fatty acid amides, including the neuromodulatory compounds anandamide and oleamide. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2022The c.50C>T (p.A17V) alteration is located in exon 1 (coding exon 1) of the FAAH gene. This alteration results from a C to T substitution at nucleotide position 50, causing the alanine (A) at amino acid position 17 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
