摘要
Objective To explore the association of the calcitonin receptor （CTR） allelic polymorphism in the 1 377 bp region with the risk of idiopathic hypercalciuria （IH） in the Han nationality in Hubei area, and to study the pathogenesis of IH. Methods The CTR genotypes were determined by polymerase chain reaction-restriction flagment length polymorphism in 76 patients with IH and 126 healthy controls from the Han nationality in Hubei area, using restriction endonuclease AluI. Results The distri bution frequencies of AluI alleles in the 2 groups followed the Hardy-Weinberg equilibrium. The distribution frequencies of the CC, TC and TT genotypes were 73.7%, 17.1% and 9.2% in IH patient group, and 89.7%, 9.5 % and 0.8 % in control group; the distribution frequencies of C and T alleles in the 2 groups were 84.2 %, 15.8 % and 94.4 %, 5.6 %, respectively. The distribution frequencies of T and TT alleles were higher, while those of C and CC alleles were lower, compared with control group;the differences between the 2 groups were significant （P 〈 0.05）. Conclusion The results indicate that the C/T single nucleotide polymorphism in the CTR gene play a significant role in the mechanism of IH in the Han nationality in Hubei area in China. 7 refs,2 figs,2 tabs.
