Genes affected

FFAR4 (HGNC:19061): (free fatty acid receptor 4) This gene encodes a G protein-coupled receptor (GPR) which belongs to the rhodopsin family of GPRs. The encoded protein functions as a receptor for free fatty acids, including omega-3, and participates in suppressing anti-inflammatory responses and insulin sensitizing. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2012]

Ambry Genetics

Oct 31, 2023

The c.194T>C (p.V65A) alteration is located in exon 1 (coding exon 1) of the FFAR4 gene. This alteration results from a T to C substitution at nucleotide position 194, causing the valine (V) at amino acid position 65 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
