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 GeneticsNov 24, 2024The c.428A>C (p.E143A) alteration is located in exon 3 (coding exon 3) of the FAAH gene. This alteration results from a A to C substitution at nucleotide position 428, causing the glutamic acid (E) at amino acid position 143 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
