Rs17817449

Within the FTO gene, many SNPs appear to be co-inherited. The SNP showing the strongest association with body weight (i.e. body mass index, BMI) is not rs17817449, although this SNP is one of co-inherited SNPs in the FTO gene region. For more information, refer to the FTO gene or the most studied of FTO SNPs, rs9930506.

A study of 900+ Quebec individuals reported that rs17817449 was associated with BMI (p=0.0014), weight (p=0.0059) and waist circumference (p=0.0021) under an additive model, and in addition, influenced fasting insulin (p=0.011) and HOMA-IR (p=0.038).


 * Note: The three FTO SNPs, rs1421085, rs17817449, and rs9939609, are in strong linkage disequilibrium (pairwise r2>0.97), and there are two primary haplotypes, C-G-A (42.0 %) and T-T-T (55.5 %).
