PPP1CB and obesity due to melanocortin 4 receptor deficiency: The expressions of CSNK1E (OR: 0.922, 95% CI: 0.853–0.997, p = 0.043) and PPP1CB (OR: 0.958; 95% CI: 0.922–0.995; p = 0.027) may be associated with a lower risk of obesity, while BHLHE40 (OR: 1.093, 95% CI: 1.010–1.183, p = 0.0028) may be associated with a higher risk of obesity (Supplementary Table S3).
