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 rs3751812, although this SNP is one of the co-inherited SNPs in the FTO gene region. For more information, refer to the FTO gene or the most studied FTO SNPs, rs9930506 or rs9939609. [PMID 17658951]
