| Popis: | A high frequency restriction fragment length polymorphism (RFLP) at the 3'-end of the pigeon pro alpha 2(1) collagen gene was detected using the restriction endonuclease EcoR1. The distribution of this allelic variant was analyzed in DNA isolated from White Carneau pigeons genetically susceptible to the development of spontaneous atherosclerosis. The atherogenic phenotype in individual pigeons was measured by the determination of total cholesterol and cholesterol ester levels in the celiac focus of the thoracic aorta of adult White Carneau pigeons. Aortic wall cholesterol levels correlated with an increase in lesion size. No correlation, however, was observed between allelic variants of the pigeon pro alpha 2(1) collagen gene and the atherogenic phenotype in White Carneau pigeons suggesting lack of linkage between this allelic marker and the genetic susceptibility to spontaneous atherogenesis. This is the first study of its kind in this animal model and serves to provide a basis for the further analysis of co-segregation of RFLPS in candidate genes to this polygenic phenotype. |
