We examined polymorphism of the TCTA tetranucleotide sequence in the 3rd intron of the hypoxanthine-guanine phosphoribosyltransferase (HPRT) gene in the Han population of Ningxia Province in China. We also looked for a possible relationship between STR polymorphism in the 3rd intron of the HPRT gene and primary hyperuricemia. We used Chelex-100 to extract DNA, then PCR, PAGE and silver staining for allele genotyping and DNA sequencing to obtain the distribution of the alleles. We found, for the first time, that there is high STR polymorphism in the 3rd intron of the HPRT gene. We detected 5 STR alleles in this intron in the Han population of Ningxia Province, with 15 genotypes in females; significant differences were observed in the distribution of alleles and genotypes between control and patient groups for both males and females. Alleles of the TCTA repeat in the 3rd intron of the HPRT gene were found to be associated with primary hyperuricemia; consequently, these alleles may be considered risk factors for primary hyperuricemia.
