https://www.selleckchem.com/products/rxc004.html In humans, great apes, and OWM, and probably the majority of the NWM species, the evolutionary equivalents of the HLA-F gene experienced purifying selection. In the marmoset, however, the gene was initially duplicated, but the expansion was subjected afterwards to various mechanisms of genetic inactivation, as evidenced by the presence of pseudogenes and an array of genetic artefacts in a section of the transcripts.The ultra-short dual antiplatelet therapy (DAPT) followed by P2Y12 inhibitor monotherapy might be promising after percutaneous coronary intervention (PCI). However, CYP2C19 loss-of-function (LOF) alleles have been reported to diminish the effect of clopidogrel, and clopidogrel monotherapy has a concern about the increased ischemic risk for patients with such alleles. STOPDAPT-2 is the multicenter prospective open-label, but adjudicator-blinded randomized control study comparing 1-month DAPT followed by clopidogrel monotherapy with the standard 12-month DAPT after PCI with cobalt-chromium everolimus-eluting stents. Among the participants of STOPDAPT-2, selected patients participated in a substudy of the CYP2C19 gene test. Patients with two CYP2C19*2 or *3 alleles were defined as the poor metabolizer (PM), one allele as the intermediate metabolizer (IM), and no allele as the extensive metabolizer (EM). The primary endpoint was the composite of cardiovascular and bleeding events, as defined in STOPDAPT-2. Among 750 (24.9%) patients with known CYP2C19 genotypes, 129 (17.2%) were PM, 367 (49.0%) were IM, and 254 (33.9%) were EM. The hazard ratios of 1-month DAPT relative to 12-month DAPT for the primary endpoint in PM, IM, and EM strata were 0.66 (95% CI 0.11-3.94), 1.94 (95% CI 0.60-6.31), and 0.21 (95% CI 0.02-1.78), respectively (P interaction = 0.17), and those for cardiovascular composite endpoint were 1.00 (95% CI 0.14-7.10), 6.10 (95% CI 0.75-49.55), and 0.26 (95% CI 0.03-2.34), respectively (P interactio
