This is consistent with previous reports showing no or little effect on glucose homeostasis in CMKLR1-knockout mice (Rouger et al., 2013; Gruben et al., 2014) whereas GPR1-knockout mice on high-fat diet have increased glucose intolerance compared to wild-type mice (Rourke et al., 2014). The gene discussed is CMKLR1; the disease is Glucose intolerance.
