ABSTRACT
<p><b>OBJECTIVE</b>To investigate collagen type I alpha 1 (COL1A1) and alpha 2 (COL1A2) gene polymorphisms in Chinese and their relationship with bone mineral density.</p><p><b>METHODS</b>Totalling 628 residents of Han nationality in Guangzhou aged 53.4-15.9 (range 20-79) years were surveyed for COL1A1 and COL1A2 gene genotypes by polymerase chain reaction-restriction fragment length polymorphism. Bone mineral density of the lumbar vertebrae, greater trochanter, femur neck and Ward's triangle was measured by dual-energy X-ray absorptiometry.</p><p><b>RESULTS</b>COL1A1 Sp1 polymorphism was not found in these subjects, and the genotype of all samples were type SS. COL1A2 genotyping revealed the distribution of EE genotype in 49.7%, Ee in 40.9% and ee in 9.4% of the subjects. The frequency distribution of EcoR1 alleles followed the Hardy-Weinberg equilibrium. The mean bone mineral density did no significantly differ among these genotype groups (P>0.05 by analysis of variance).</p><p><b>CONCLUSION</b>COL1A1 Sp1 binding site polymorphism is absent and COL1A2 EcoR1 site polymorphism is not associated with bone mineral density in Chinese of Han nationality.</p>
