In European populations, the NPPB rs198389 single nucleotide polymorphism (SNP) is associated with a reduced risk of type 2 diabetes mellitus (T2DM). We investigated the putative associations between NPPB rs198389, the T2DM risk and quantitative metabolic traits in an Algerian population. Methods: The association analysis was performed as a T2DM case-control study (with 78 cases and 645 controls) nested into the ISOR population-based study. Results: The NPPB rs198389 SNP was not associated with T2DM (odds ratio (OR) [95% confidence interval (CI)] = 0.73 [0.51-1.04], p= 0.08). However, the C allele was associated with lower fasting plasma insulin levels (p= 0.05) and a lower homeostatic model assessment insulin resistance index (p= 0.05) in non-diabetic individuals. Conclusion: The NPPB rs198389 SNP might modulate fasting insulin levels in an Algerian population.
