N2  - Fragility fractures resulting from low-trauma events such as a fall from standing height are associated with osteoporosis and are very common in older people, especially women. Three SNPs at the COL1A1 gene (rs1107946, rs11327935, rs1800012) have been widely studied and previously associated with BMD and fracture. A rare haplotype (T-delT-T) of these three SNPs was found to be greatly overrepresented in fractured individuals compared with non-fractured controls, thus becoming a good candidate for predicting increased fracture risk. The aim of our study was to assess the association of this haplotype with fracture risk in a Spanish cohort. We recruited two independent groups of ∼100 patients with hip fracture (a total of 203 individuals) and compared the genotype and haplotype distributions of the three SNPs in the fractured patients with those of 397 control individuals from the BARCOS Spanish cohort. We found no association with risk of fracture at the genotype level for any of the SNPs, and no differences in the SNP frequencies between the two groups. At the haplotype level, we found no association between the T-delT-T haplotype and fracture. However, we observed a small but significant (p = 0.03) association with another rare haplotype, G-insT-T, which was slightly overrepresented in the patient group. © 2011 American Society for Bone and Mineral Research.<p />  <p>Language: en</p>
