Global genome-wide association studies have listed at least 19 <jats:italic>WFS1<\/jats:italic> variants that are associated with type 2 diabetes (T2D) and metabolic traits. It has been suggested that miRNA binding sites on <jats:italic>WFS1<\/jats:italic> play a critical role in the regulation of the wolframin protein, and loss of WFS1 function may lead to the pathogenesis of diabetes. In the Hungarian population, it was observed that a 3\u2019 UTR variant from <jats:italic>WFS1<\/jats:italic>, namely rs1046322, influenced the affinity of miR-668 to <jats:italic>WFS1<\/jats:italic> mRNA, and showed a strong association with T2D. In this study, we genotyped a large cohort of 2067 individuals of different ethnicities residing in Kuwait for the <jats:italic>WFS1<\/jats:italic> rs1046322 polymorphism. The cohort included 362 Southeast Asians (SEA), 1045 Arabs, and 660 South Asians (SA). Upon performing genetic association tests, we observed significant associations between the rs1046322 SNP and obesity traits in the SEA population, but not in the Arab or SA populations. The associated traits in SEA cohort were body mass index, BMI (\u03b2=1.562, P-value=0.0035, P<jats:italic><jats:sub>emp<\/jats:sub>=0.0072<\/jats:italic>), waist circumference, WC (\u03b2=3.163, P-value=0.0197, P<jats:italic><jats:sub>emp<\/jats:sub>=0.0388<\/jats:italic>) and triglyceride, TGL (\u03b2=0.224, P-value=0.0340). The association with BMI remained statistically significant even after multiple testing correction. Among the SEA individuals, carriers of the effect allele at the SNP had significantly higher BMI [mean of 27.63 (3.6) Kg\/m<jats:sup>2<\/jats:sup>], WC [mean of 89.9 (8.1) cm], and TGL levels [mean of 1.672 (0.8) mmol\/l] than non-carriers of the effect allele. Our findings suggest a role for <jats:italic>WFS1<\/jats:italic> in obesity, which is a risk factor for diabetes. The study also emphasizes the significant role the ethnic background may play in determining the effect of genetic variants on susceptibility to metabolic diseases.<\/jats:p>","DOI":"10.3389\/fendo.2023.1185956","type":"journal-article","created":{"date-parts":[[2023,10,4]],"date-time":"2023-10-04T10:57:50Z","timestamp":1696417070000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["The
