In another genome-wide association study, body mass index and waist circumference were strongly correlated with SNPs in the Prox1 gene from 1049 Mongolian individuals, revealing that the 1q32 and 10q11.22 loci near the Prox1 gene were new candidate loci for obesity (78). Here, PROX1 is linked to obesity due to melanocortin 4 receptor deficiency.
