Given that susceptibility to type 2 diabetes appears in large measure due to genetic makeup, investigators have spent years of effort trying to identify genes that influence type 2 diabetes risk. An important goal of gene identification is to improve our understanding of the pathophysiology of diabetes, leading to new measures of diagnosis, prevention, and treatment. A diabetes gene is consider...

Oral antidiabetic drugs (OADs) are widely used to treat type 2 diabetes mellitus (T2DM). However, inherited difference is one of the major issues that affect OADs therapeutic efficacy. In the present paper, we performed a critical review on recent advances in genetic polymorphisms that influence OADs therapeutic efficacy and metabolism. Sulfonylureas (SUs), Meglitinides, Metformin and Thiazolid...

AIM Our aim was to investigate the relationship between transcription factor 7-like 2 (TCF7L2) polymorphisms and breast cancer susceptibility. METHODS PubMed, Embase and CNKI databases were used to search the related studies investigating the correlation between TCF7L2 polymorphisms and breast cancer susceptibility. Pooled ORs and 95% CIs, based on five genetic models, were applied to estimat...

BACKGROUND Evidence has accumulated that multiple genetic and environmental factors play important roles in determining susceptibility to type 2 diabetes (T2D). Although variants from candidate genes have become prime targets for genetic analysis, few studies have considered their interplay. Our goal was to evaluate interactions among SNPs within genes frequently identified as associated with T...

OBJECTIVE Genetic polymorphisms of the transcription factor 7-like 2 (TCF7L2) gene is one of the few validated genetic variants with large effects on the risk of type 2 diabetes in the populations of European ancestry. In this study, we aimed to explore the effect of the TCF7L2 polymorphisms in a Han Chinese population. RESEARCH DESIGN AND METHODS We genotyped 20 single nucleotide polymorphis...

BACKGROUND & OBJECTIVES With increasing number of people with diabetes worldwide, particularly in India, it is necessary to search for low cost screening methods. We compared the effectiveness and costs of screening for undiagnosed type 2 diabetes mellitus (T2DM), using oral glucose tolerance testing (OGTT) alone, or following a positive result from the Indian Diabetes Risk Score (IDRS) or foll...

OBJECTIVE The transcription factor 7-like 2 (TCF7L2) gene was initially reported to be associated with type 2 diabetes in Icelandic, Danish, and U.S. populations. We investigated whether TCF7L2 also has a role in type 2 diabetes susceptibility in Pima Indians. RESEARCH DESIGN AND METHODS The six variants reported to be associated with type 2 diabetes in the Icelandic study were genotyped in a...

Polycystic ovary syndrome (PCOS) is a complex genetic disease characterized by heritable reproductive and metabolic abnormalities. Genetic variants associated with the reproductive phenotype have been mapped to the fibrillin-3 (FBN3) gene and to a novel transcription factor-7-like 2 (TCF7L2) locus (rs11196236 G). The association of these genetic variants with metabolic phenotypes was investigat...
