However one recent well-powered study by Elks et al. found a modest association between an obesity risk score comprising alleles from FTO, MC4R, TMEM18, GNPDA2, KCTD15, NEGR1, BDNF and ETV5 (SFRS10) loci and BMI at birth in 7,146 individuals. The gene discussed is KCTD15; the disease is obesity due to melanocortin 4 receptor deficiency.
