Common Genetic Variants in SIRT1 Gene Promoter and Type 2 Diabetes Mellitus in Saudi Arabia.

Background: Type 2 diabetes mellitus (T2DM) is common in Saudi Arabia and represents a major health concern. Silent information regulator of transcription-1 (SIRT1) positively influences insulin sensitivity and might contribute to the pathogenesis of T2DM. This study aimed to investigate the frequency of two common functional single nucleotide polymorphisms (SNPs) in the promoter region of SIRT1; rs12778366 (T>C) and rs3758391 (T>C) in Saudi Arabian population and examine any association with T2DM.
