RESUMEN

<p><b>OBJECTIVE</b>To investigate the distribution of single nucleotide polymorphisms (SNPs) in CAPN10 gene in Chinese population and their relation with type 2 diabetes mellitus in Han people of Northern China.</p><p><b>METHODS</b>CAPN10 gene was sequenced to detect SNPs in different nationalities of China. Five SNPs were chosen to perform case-control study and haplotype analysis in 156 normal Han people of Northern China and 173 type 2 diabetes. One SNP was also analyzed with transmission-disequilibrium test (TDT) and sib transmission-disequilibrium test (STDT) in 68 type 2 diabetes pedigrees (377 people).</p><p><b>RESULTS</b>A total of 40 SNPs were identified in length of 8,936 bp, with an average of 1 in every 223 bp. The SNPs in CAPN10 gene did not distribute evenly and the SNPs in Chinese were different from those reported in Mexican American. There was no significantly statistical difference in the allele frequency of the 5 SNPs between case and control, and the haplotype frequencies in the two groups were not significantly different. No positive results was found in TDT and STDT analysis.</p><p><b>CONCLUSIONS</b>The SNP distribution of CAPN10 gene differs in different nationalities. The studied SNPs in CAPN10 gene may not be the major susceptibility ones of type 2 diabetes mellitus in Han people of Northern China.</p>

RESUMEN

<p><b>OBJECTIVE</b>To investigate the distribution of the single nucleotide polymorphisms (SNPs) in CAPN10 gene in Chinese population and their relation with type 2 diabetes mellitus in Han people of Northern China.</p><p><b>METHODS</b>CAPN10 gene was sequenced to detect SNPs in 27 samples of different nationalities in China. 5 SNPs were genotyped with single-base extension (SBE) method to perform case-control study in 156 normal Han people of Northern China and 173 type 2 diabetes and the 3 positive loci reported in the article were performed haplotype analysis. One positive locus was also analyzed with transmission-disequilibrium test (TDT) and sib transmission-disequilibrium test (STDT) in 68 type 2 diabetes pedigrees (377 cases).</p><p><b>RESULTS</b>A total of 40 SNPs were identified in length of 8,936 bp, with an average of 1 in every 223 bp; The SNPs in CAPN10 gene did not distribute evenly and the SNPs in Chinese was different from that reported in American Mexicans. There was no significantly statistical difference in the allele frequency of the 5 SNPs between case and control (P > 0.05), and the haplotype frequencies in the two groups were not much different (P > 0.05). There was no positive results in TDT and STDT analysis (P > 0.05).</p><p><b>CONCLUSIONS</b>The SNP distribution of CAPN10 gene varies with different nationalities. The studied SNPs in CAPN10 gene may not be the major susceptibility ones of type 2 diabetes mellitus in Han people of Northern China.</p>
