Abstract

Summary

This study evaluated the association of a polymorphism in the CD40 gene with BMD and risk of osteopenia or osteoporosis in a population of 602 postmenopausal women. Results showed that women with the TT genotype had lower BMD at femoral neck and spine sites and increased risk of osteopenia or osteoporosis.

Introduction

Recent findings have demonstrated that the CD40/CD40L system, which is of main importance for the immune system, can also be implied in the regulation of bone metabolism. The main objective of the present work has been to clarify whether single nucleotide polymorphisms (SNPs) affecting genes of CD40/CD40L system could be linked with abnormalities in the level of bone mineral density (BMD) in menopausal women.

Methods

We performed an association study of BMD values with a SNP located at position −1 of the Kozak consensus sequence of CD40 gene (rs1883832; C > T) in a population of 602 postmenopausal women.

Results

Women with the TT genotype (8.6% of women) displayed a reduction in femoral neck BMD (FN BMD) and lumbar spine BMD (LS BMD) of 6.2% and of 6.3%, respectively, as compared to women with CC + CT genotype. Logistic regression analysis adjusted for age, weight, and height showed that women with the TT genotype had increased risk for FN (odds ratio: 2.34; 95% CI: 1.12–4.89) and LS (odds ratio: 2.49; 95% CI: 1.19–5.24) osteopenia or osteoporosis.

Conclusions

Women with the TT genotype in rs1883832 SNP affecting to Kozak consensus sequence of CD40 gene had lower BMD at FN and at LS sites and increased risk of osteopenia or osteoporosis.
