Abstract
Background and aims
Osteoporosis leads to high fracture risk and evidence suggests that genetic factors play an important role in this disease. The aim was to evaluate the association of two polymorphisms (−1997G/T, +1245G/T) in the collagen type1 alpha 1 gene (COL1A1) with fracture or with low bone mineral density (BMD) at the hip in postmenopausal Mexican women.
Methods
BMD was determined by bone densitometry and the risk factors were collected with a questionnaire. Genotyping was performed by real-time PCR.
Results
The polymorphisms were in Hardy–Weinberg equilibrium. The −1997G/+1245T haplotype showed, after adjustment for confounders, a fourfold increased risk of hip fracture [OR 4.32; p = 0.041 (95 % CI 1.07–17.43)]; while in the women with low BMD at the hip, the risk was increased threefold [OR 3.36; p = 0.022 (95 % CI 1.20–9.40)].
Conclusions
The results support the association of COL1A1 gene polymorphisms with fracture and with low BMD at the hip in Mexican population.
