Type 2 or non-insulin-dependent diabetes mellitus (NIDDM) is the most common form of diabetes worldwide, affecting approximately 4% of the world's adult population. It is multifactorial in origin with both genetic and environmental factors contributing to its development. A genome-wide screen for type 2 diabetes genes carried out in Mexican Americans(More)
Mexico is developing the basis for genomic medicine to improve healthcare of its population. The extensive study of genetic diversity and linkage disequilibrium structure of different populations has made it possible to develop tagging and imputation strategies to comprehensively analyze common genetic variation in association studies of complex diseases.(More)
A positional cloning study of type 2 diabetes in Mexican Americans identified a region, termed "NIDDM1," on chromosome 2q37 with significant linkage evidence. Haplotype combinations at the calpain-10 gene (CAPN10) within this region were shown to increase diabetes risk in several populations. On the basis of the thrifty genotype hypothesis, variants that(More)
Several studies have identified nearly 40 different type 2 diabetes susceptibility loci, mainly in European populations, but few of them have been evaluated in the Mexican population. The aim of this study was to examine the extent to which 24 common genetic variants previously associated with type 2 diabetes are associated in Mexican Mestizos. Twenty-four(More)
Variation in the calpain-10 gene (CAPN10) has been associated with risk of type 2 diabetes in the Mexican American population of Starr County, Texas. We typed five polymorphisms in the calpain-10 gene (SNP-43, -43, -63, and -110 and Indel-19) to test for association with type 2 diabetes in 248 individuals representative of the mestizo population of Mexico(More)
Variation in the gene encoding the cysteine protease calpain-10 has been linked and associated with risk of type 2 diabetes. We have examined the effect of three polymorphisms in the calpain-10 gene (SNP-43, Indel-19, and SNP-63) on the development of type 2 diabetes in the Japanese population in a pooled analysis of 927 patients and 929 controls. We(More)
We investigated the patterns and extent of linkage disequilibrium (LD) in the vicinity of the type 2 diabetes gene calapin-10 (CAPN10) in Mexican Americans, European Americans, African Americans, and Chinese Americans. We found that CAPN10 occurs within a single block of high LD and that LD decays rapidly outside of the gene. This reduces the likelihood(More)
Mutations in transcription factors that play a role in the development of the endocrine pancreas, such as insulin promoter factor-1 and NeuroD1/BETA2, have been associated with diabetes. Cell type-specific members of the basic helix-loop-helix (bHLH) family of transcription factors play essential roles in the development and maintenance of many(More)
Metabolomics is a promising approach for the identification of chemical compounds that serve for early detection, diagnosis, prediction of therapeutic response and prognosis of disease. Moreover, metabolomics has shown to increase the diagnostic threshold and prediction of type 2 diabetes. Evidence suggests that branched-chain amino acids, acylcarnitines(More)
