We utilized COJO analysis [23,24] to look for secondary association signals for the Tier-1 SNPs at neighboring FAM13A and RP11-392O17.1. This analysis revealed three FAM13A-associated EnhPro SNPs (i.e., rs17014602, rs4544678, and rs3775378) that might still be credible obesity risk-associated variants. Here, FAM13A is linked to obesity due to melanocortin 4 receptor deficiency.
