Abstract: Charles University in Prague, The First Faculty of Medicine Thesis: Variability in LPA gene transcription regulatory sequences Name: Mgr. Kateřina Zídková Thesis Adviser: Prof. Richard Češka, M.D., Ph.D. Consulting Thesis Adviser: Assoc. Prof. Milada Kohoutová, M.D., Ph.D. Summury of Doctorate thesis Increased Lp(a) concentration is an independent risk factor for premature atherosclerosis. The Lp(a) concentration is almost entirely genetically determined with an exclusive linkage to a unique locus, the gene for apo(a), so called LPA locus. Nevertheless Lp(a) concentrations varies widely between individuals in all populations studied so far. There is a LPA gene size heterogeneity (KLPAIV type 2 repetition) accounting for 40-60% of the variance. Some of the variance could be additionally related to polymorphic sites either in the coding sequence or in transcription regulatory regions of LPA gene. We had scanned the LPA gene transcription regulatory regions (promoter, DHII, and DHIII enhancers) for variabilty. None of them was revealed to be extremely polymorphic. However significant linkage disequilibrium was detected even between polymorphic sites from far regulatory sequences. We have investigated if certain compound genotypes of apo(a) gene regulatory sequences could be associated with a narrow range of...
