Variant 1-46394428-T-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001441.3(FAAH):c.80T>C(p.Val27Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000762 in 1,312,326 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V27L) has been classified as Uncertain significance.

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]

Ambry Genetics

Oct 20, 2023

The c.80T>C (p.V27A) alteration is located in exon 1 (coding exon 1) of the FAAH gene. This alteration results from a T to C substitution at nucleotide position 80, causing the valine (V) at amino acid position 27 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
