Abstract
Aims/hypothesis
Dyslipidaemia, a common feature of type 2 diabetes, is characterised by an increase in atherogenic particles, quantifiable through apolipoprotein B (ApoB) levels. Genetic studies of lipid levels have focused on Europeans; a study in South Asians could identify novel genes.
Methods
We tested 31,739 single nucleotide polymorphisms (SNPs) from ∼2,000 genes in 2,573 South Asians from the epidemiological arm of the Diabetes Reduction Assessment with Ramipril and Rosiglitazone Medication (DREAM) study (EpiDREAM) for association with ApoB and we tested two novel associations for replication in 1,181 South Asians from the INTERHEART case–control study.
Results
The SNP, rs4664443, within DPP4 was associated with ApoB (p = 7.98 × 10−5) in EpiDREAM. The observed association was replicated in the INTERHEART South Asians (one-sided p = 9.65 × 10−3; combined two-sided p = 4.68 × 10−6). The rs4664443 SNP was not associated with ApoB among five other EpiDREAM ethnicities. However, because South Asians had a significantly lower mean BMI compared with other EpiDREAM ethnicities, we tested for and found an interaction between rs4664443 and BMI for ApoB among the Europeans, the largest subgroup in EpiDREAM (p = 4.14 × 10−3 for interaction), observing an association with ApoB in Europeans with a BMI <25 kg/m2 (p = 2.35 × 10−3), but not with a BMI ≥25 kg/m2 (p = 0.21). The association between rs4664443 and ApoB among all EpiDREAM individuals with BMI <25 kg/m2 was significant (n = 2,972; p = 1.44 × 10−5) compared with those with a BMI ≥25 kg/m2 (n = 11,559; p = 0.81), and there was evidence of association among all genotyped individuals with a BMI <25 kg/m2, including the INTERHEART South Asians (n = 3,601; p = 9.52 × 10−7).
Conclusion/interpretation
Variation at the DPP4 locus is associated with ApoB in South Asians and displays heterogeneity related to BMI in other ethnicities.
