rs1528133, a SNP in the TUB gene, was found in a study of 492 unrelated type-2 diabetes patients to have a significant effect on body mass index and thus obesity (1.54 kg/m(2), p= 0.006). When two populations were combined, totaling ~1200 patients, the risk allele (rs1528133(C) averaged an increase of 0.54 kg/m2 (CI: â€“0.19-1.26). Two additional TUB SNPs, rs2272382, and rs2272383, mapping to the 3' end of the gene showed similar associations and were in linkage disequilibrium with rs1528133.[PMID 16443771]
A follow-up study of 1,680 middle-aged Dutch women found that this allele, rs1528133(C), was significantly associated with increased weight (+1.88 kg, p=0.022) and body mass index (+0.56 units, p= 0.05). rs1528133(C) carriers were also associated with an increased glycemic load of 1.85 units compared with non-carriers.[PMID 18183286]
