Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 07, 2023The c.547G>A (p.V183M) alteration is located in exon 4 (coding exon 4) of the FAAH gene. This alteration results from a G to A substitution at nucleotide position 547, causing the valine (V) at amino acid position 183 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
