老年男性维生素D受体基因(Fok1)多态性与骨质疏松的关系
Relationship between vitamin D receptor gene (Fok 1) polymorphism and osteoporosis in the elderly men
摘要
Abstract
BACKGROUND: It is found reported that polymorphism of Fok 1 restriction endonuclease cut site on exon 2 of 5' end start codon of 5' end start codon (SC), which affected the structure of VDR amino acids,and was relative related to bone mineral density(BMD).OBJECTIVE: To analyze the association between Vitamin D receptor gene (Fok 1) polymorphisms and osteoporosis in the elderly men.DESIGN: case-controlled trialstudy.SETTING: Institute of Gerontology, Chinese PLA General Hospital and Department of Endocrinology,Second Artillery General Hospital of Chinese PLA.PARTICIPANTS: A total of 26 elderly men with osteoporosis at out-patients clinic of Chinese PLA General Hospital and Department of Endocrinology,Second Artillery General Hospital of Chinese PLA from January 2002 to June 2002 were selected involved as osteoporosis case group,with and the average age of was (70±5) years, and BMD in osteoporosis group was 2.0-2.5 SD lower than 2.0-2.5 SD of the peak of BMD. Totally 66 healthy men with average age of (70±5)years were selected as control group during at the same time. All the subjects signed the informed consent,who were Beijing inhabitants of Han nationality, and there was no blood relationship among them.METHODS:VDR-Fok1 genotypes in both groups were detected with by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP),and distributiondistribution of VDR-Fok 1 genotypes were analyzedanalyzed.MAIN OUTCOME MEASURES: distribution Distribution of VDR-Fok1genotypes in both each groups.RESULTS: Totally 66 healthy elderly men and 26 elderly men with osteoporosis entered analysis of results. The frequencies of FF, Ff and ff genotype were found to be 42%, 42% and 15% in control group, and 15%,50%,35% in osteoporosis group, respectively,and there was significantly different between two groups(x2=12.078,P ＜ 0.01).Frequency of allele were significantly different between control group and osteoporosis group (64%,36% vs 40%,60%, x2=8.232,P ＜ 0.01).CONCLUSION: There is a significant difference in the frequency distrinution of VDR gene start codon polymorphism between healthy elderly men and those with osteoporosis.关键词
