Some of the pathways found to be associated with BMI are Cell cycle, Steroid biosynthesis, SNARE interactions in vesicular transport, Viral myocarditis, Fc epsilon RI signalling pathway, TGF-β pathway, Haematopoietic cell lineage, Glioma, Melanogenesis and Jak-STAT signalling pathway. This evidence concerns the gene SOAT1 and central nervous system cancer.
