FTO and obesity disorder: However, in a prior GWA study, the C allele of rs8044769 FTO SNP—which is related to a positive affective response to PA, and hence, should lead to a higher volume of PA in the future—was, counterintuitively, reported to be associated with higher BMI47; similarly, another obesity prone FTO SNP (i.e., A allele of rs9939609) was associated with being more physically active compared to non-carriers in 71 Scottish children 4 to 10 years of age.
