Genetic polymorphisms and haplotype structures of HSPA5 gene in the Han population of Southern China.

The heat shock 70 kDa protein 5 (HSPA5) gene is known to be involved in stress-associated diseases. In this study, the promoter, exons, 3' untranslated region (3'UTR), and subtotal introns of the HSPA5 gene were sequenced in a sub-population of 161 healthy Han Chinese. Nine single-nucleotide polymorphisms (SNPs) including a new one (-86bp T > A from the estimated translation start site) were found and 15 haplotypes (frequencies > 1%) were inferred. Polymorphisms rs391957 and rs11355458 were completely linked in our population (r (2) = 1.00). Using this information, fellow scientists may be able to decrease the number of SNPs to be genotyped in future disease case-control studies.
