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 [[rs9923233]], 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]]. {{PMID|17658951|OA=1
