Aims/hypothesis The gene encoding solute carrier family 2, facilitated glucose transporter, member 10 (SLC2A10, previously known as glucose transporter 10 [GLUT10]) is a promising candidate gene for type 2 diabetes since it is highly expressed in liver and pancreas and is located on human chromosome region 20q12–q13.1, a region previously shown to harbour type 2 diabetes susceptibility genes. We investigated whether the SLC2A10 gene could be a type 2 diabetes susceptibility gene in the Taiwanese population. Subjects and methods Sequencing of SLC2A10 gene from 48 diabetic subjects detected short tandem repeat polymorphisms in the promoter region, but did not detect any other sequence variants or new single-nucleotide polymorphisms ( SNPs) other than those already in the SNPper database (http: //snpper.chip.org) (30 June 2005). Results Using these genetic polymorphisms, we divided the SLC2A10 gene into four distinct linkage disequilibrium blocks and performed a case -control association study in a group of type 2 diabetes subjects (n=375) and normoglycaemic individuals (n=377). The HapD (A-G-T-C) haplotype in block 3, a rare haplotype, which consisted of four SNPs (rs3092412, rs2235491, rs 2425904 and rs1059217), was modestly associated with type 2 diabetes with a haplotype score of 2.95567 (p=0.012 with the haplotype- specific test). Conclusions/ interpretation Our results suggest that SLC2A 10 genetic variations do not appear to be major determinants for type 2 diabetes susceptibility in the Taiwanese population.
