Aims

Previous genome-wide association studies reported rs1440581 was significantly associated with circulating branched chain amino acids (BCAAs) levels in Europeans. We aimed to investigate association of BCAAs related variant rs1440581 with incident T2D risk and longitudinal changes in glucose-related metabolic traits in a community-based prospective cohort of Chinese.

Methods

6043 non-diabetic participants aged ≥ 40 years from a community-based population at baseline were included and followed-up for 5 years. The BCAAs related variant rs1440581 was genotyped. Incident T2D was defined as fasting plasma glucose (FPG) ≥ 7.0 mmol/L or taking anti-diabetic therapy. Anthropometry and biochemical measurements were evaluated at both baseline and follow-up.

Results

576 (9.5%) participants developed T2D during the 5-year follow-up. Each C-allele was associated with a 20% higher risk of incident T2D (odds ratio = 1.20, 95% confidence interval [1.05, 1.36]) after adjustments for the confounders. We did not find a main effect of the variant on increase in fasting serum insulin (FSI) level or insulin resistance (IR). However, we found rs1440581 significantly modified effect of weight gain on increase in FSI and HOMA-IR. In the C-allele carriers, body mass index increase was associated with greater increase in Log10_FSI (β ± SE 0.027 ± 0.002) and Log10_HOMA-IR (0.030 ± 0.003), as compared to T-allele (both P for interaction = 0.003).

Conclusions

BCAAs related genetic variant rs1440581 was associated with an increased risk of incident T2D in a Chinese population. This variant might modify effect of weight gain on development in IR."xsd:string
