A genetic variant of the NAMPT gene rs4730153 as a risk factor for the metabolic syndrome in younger age: a single-centre pilot study in Yogyakarta, Indonesia

Abstract

Abstract Background The genetic variation of nicotinamide phosphoribosyl transferase (NAMPT) gene rs4730153 is reported to be associated with cardiometabolic risk, but the results are inconsistent between populations. Ethnicity, metabolic risk and lifestyle play a role in the association of the genetic variant and the metabolic syndrome (MetS). To the best of our knowledge, no research has yet been published concerning the Javanese population, so this study aimed to investigate the association of rs4730153 with MetS and its interaction with metabolic risk and lifestyle. Results The GG genotype (p = 0.031; OR 95% CI 3.88 [1.13–13.33]), GA+GG genotype (p = 0.048; OR 95% CI 10.52 [1.02–108.01]) and G allele carrier (p = 0.006; OR 95% CI 4.19 [1.51–11.64]) of rs4730153 had a higher risk of the MetS after adjusting for obesity, hypercholesterolemia, smoking and food intake. The risk was statistically significant for the younger age group ≤ 45 years old. Conclusion The GG, GA+GG genotype and G allele carrier of rs4730153 have a higher risk of the MetS, especially those who are obese, hypercholesterolemic and smokers and have a higher food intake in those aged ≤ 45 years old. Further larger, multicentre studies are required to confirm these pilot results.
