FTO and obesity due to melanocortin 4 receptor deficiency: Wing et al. [39] genotyped 26 SNPs in intron 1 of FTO in 373 Hispanic Americans and observed associations between BMI and several SNPs that were previously reported to be associated with obesity (rs9939609, rs8050136, rs1121980, rs1421085, rs17817449 and rs3751812), and four other SNPs (rs8047395, rs10852521, rs8057044 and rs8044769).
