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]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.006087482).
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0108 (1639/152354) while in subpopulation AFR AF = 0.037 (1539/41596). AF 95% confidence interval is 0.0355. There are 27 homozygotes in GnomAd4. There are 763 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 27 AR gene
