FTO and obesity due to melanocortin 4 receptor deficiency: Gram-positive infections could be explained in part by higher incidence of T2D in genetic variants of FTO. By analyzing other SNPs not significantly associated with BMI in our analysis, we also identified a few other potential associations with less common traits not associated with obesity (periodontitis, non-inflammatory diseases of the cervix); neither of these SNPs is in high LD with obesity-related SNPs.
