The rs10830963 SNP of the MTNR1B gene in the Czech cohort.

Disruptions in biorhythms contribute to the development of type 2 diabetes mellitus. The <i>MTNR1B</i> gene encodes a receptor for melatonin, a hormone regulating biorhythms, and genetic studies suggest that variability in the <i>MTNR1B</i> gene is related to the development of T2DM, with the single nucleotide polymorphism rs10830963 showing the strongest association. Our aim was to compare the distribution of the genetic variant rs10830963 between persons differing in glucose tolerance (N=1206).

生物节律紊乱可促进2型糖尿病（type 2 diabetes mellitus, T2DM）的发生发展。<i>MTNR1B</i>基因编码褪黑素受体，褪黑素是一种调控生物节律的激素；既往遗传学研究表明，<i>MTNR1B</i>基因的多态性与2型糖尿病的发生相关，其中单核苷酸多态性rs10830963的关联效应最为显著。本研究旨在比较糖耐量水平不同的受试者（N=1206）中遗传变异rs10830963的分布情况。
