Ambry Genetics

Apr 11, 2023

The c.820G>C (p.E274Q) alteration is located in exon 6 (coding exon 6) of the FAAH gene. This alteration results from a G to C substitution at nucleotide position 820, causing the glutamic acid (E) at amino acid position 274 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
