Obesity is a public health crisis, and its prevalence disproportionately affects African Americans in the United States. Dysregulation of organelle calcium homeostasis is associated with obesity. The mitochondrial calcium uniporter () complex is primarily responsible for mitochondrial calcium homeostasis. Obesity is a multifactorial disease in which genetic underpinnings such as single-nucleotide polymorphisms (SNPs) may contribute to disease progression. The objective of this study was to identify genetic variations of with anthropometric measurements and obesity in the All of Us Research Program.
We used an additive genetic model to assess the association between obesity traits (body mass index (BMI), waist and hip circumference) and selected SNPs in 19,325 participants (3221 normal weight and 16,104 obese). Eleven common SNPs with a minor allele frequency ≥ 5% were used for analysis.
We observed three SNPs in self-reported Black/African American (B/AA) men, and six SNPs in B/AA women associated with increased risk of obesity, whereas six SNPs in White men, and nine SNPs in White women were protective against obesity development.
This study found associations of SNPs with obesity, providing evidence of a potential predictor of obesity susceptibility in B/AA adults.
肥胖是一场公共卫生危机,其患病率对美国非裔美国人的影响尤为严重。细胞器钙稳态失调与肥胖有关。线粒体钙单向转运体(MCU)复合体主要负责线粒体钙稳态。肥胖是一种多因素疾病,单核苷酸多态性(SNP)等遗传因素可能会促进疾病进展。本研究的目的是在“我们所有人”研究项目中确定MCU基因变异与人体测量指标及肥胖之间的关系。
我们采用加性遗传模型评估肥胖特征(体重指数(BMI)、腰围和臀围)与19325名参与者(3221名体重正常者和16104名肥胖者)中选定的MCU基因SNP之间的关联。使用11个次要等位基因频率≥5%的常见MCU基因SNP进行分析。
我们观察到,在自我报告的黑人/非裔美国(B/AA)男性中有3个MCU基因SNP,在B/AA女性中有6个MCU基因SNP与肥胖风险增加相关,而在白人男性中有6个MCU基因SNP,在白人女性中有9个MCU基因SNP对肥胖发展具有保护作用。
本研究发现MCU基因SNP与肥胖有关,为B/AA成年人肥胖易感性的潜在预测指标提供了证据。
