This SNP is in a linkage block in the FTO gene with rs1121980; see rs1121980 for the association of this block with early onset obesity since it showed the strongest association. This SNP did not show any association with obesity, type-2 diabetes or any other related traits in a study of 3,210 Chinese subjects. Furthermore, the minor allele frequency was much lower in Chinese populations compared to populations of European descent. However, a more recent study of 4,189 Chinese Han subjects combined with a meta-analysis of published studies concluded that rs8050136(A) was associated with both increased risk for type-2 diabetes and obesity. rs8050136 associated with increased food intake, but not of impaired energy expenditure.
