Genes affected

F2RL3 (HGNC:3540): (F2R like thrombin or trypsin receptor 3) This gene encodes a member of the protease-activated receptor subfamily, part of the G-protein coupled receptor 1 family of proteins. The encoded receptor is proteolytically processed to reveal an extracellular N-terminal tethered ligand that binds to and activates the receptor. This receptor plays a role in blood coagulation, inflammation and response to pain. Hypomethylation at this gene may be associated with lung cancer in human patients. [provided by RefSeq, Sep 2016]

The c.421C>A (p.R141S) alteration is located in exon 2 (coding exon 2) of the F2RL3 gene. This alteration results from a C to A substitution at nucleotide position 421, causing the arginine (R) at amino acid position 141 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
