2007年,在头两项关于肥胖性状的全基因组关联研究中,聚集在FTO第一内含子上的SNPs显示出高度显著的相关性,其中次要等位基因使体重指数(BMI)增加0.39公斤/平方米(或体重增加1130克),肥胖风险增加1.20倍。随后的研究令人信服地证实了这种关系在不同血统的人群中和整个生命过程中都存在,其中以年轻成年人的影响最大。在非洲和亚洲血统的人群中,FTO SNPs对肥胖特征的影响与欧洲血统的人群相似或略小,但BMI增加的等位基因在非欧洲血统的人群中的流行程度要低得多。FTO SNP不影响体力活动水平,然而,在体力活动的个体中,FTO对肥胖易感性的影响减弱了约30%。来自流行病学和功能研究的越来越多的证据表明,FTO通过食物摄入量和偏好的微妙变化增加了肥胖的风险。此外,最近出现的数据表明,FTO在感知营养以及调节翻译和生长方面发挥了作用。在这篇综述中,我们探讨了FTO的遗传流行病学,并讨论了其复杂的生物学可能如何与体重调节有关。
In 2007, SNPs that cluster in the first intron of FTO showed highly significant association in the first two genome-wide association studies for obesity traits of which the minor allele increases body mass index (BMI) by 0.39 kg/m2 (or 1,130 g in body weight) and risk of obesity by 1.20 fold. Subsequent studies convincingly confirmed this association across populations of diverse ancestry and throughout the life course, with the largest effect seen in young adulthood. The effect of FTO SNPs on obesity traits in African and Asian ancestry populations is similar or somewhat smaller than in European ancestry populations, but the BMI-increasing allele is substantially less prevalent in non-European ancestry populations. FTO SNPs do not influence physical activity levels, yet, in physically active individuals, FTO’s effect on obesity susceptibility is attenuated by ~30%. Growing evidence from epidemiological and functional studies suggests that FTO confers an increased risk of obesity through subtle changes in food intake and preference. In addition, recent emerging data now points to a role for FTO in the sensing of nutrients and the regulation of translation and growth. In this review, we explore the genetic epidemiology of FTO and discuss how its complex biology might link to the regulation of body weight.
