COL23A1 and obesity due to melanocortin 4 receptor deficiency: Groups 10 and 11 have similar ADMIXTURE profiles, but with a slightly different ratio of European ancestral part, with discriminatory SNPs linked to genes that enrich for obesity (enrichment p value < 0.0001), as DRD1 (SNP rs686) and COL23A1 (rs17648108—which display the lowest allele frequency in Europeans, of 0.2684, contrasting to higher than 0.5 in other population groups).
