Objective: The objective was to study the polymorphism of collagen type 1 alpha 1 (COL1 A1) gene as a genetic marker, the biochemical markers of formation (osteocalcin) and bone reabsorption (cross-links of pyridinoline-CTx), bone mineral density and bone ultrasonometry compared to bone densitometry (DEXA).
Method: The study included 82 women ranging in age from 45 to 60 years, menopausal from 1 to 10 years. Polymorphism of COL1 A1 was assessed by PCR (polymerase chain reaction), by the specific allele technique.
