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

Aug 12, 2022

The c.17C>G (p.A6G) alteration is located in exon 1 (coding exon 1) of the FFAR4 gene. This alteration results from a C to G substitution at nucleotide position 17, causing the alanine (A) at amino acid position 6 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
