Quantitative fluorescence polymerase chain reaction (QF-PCR) is a molecular genetic method based on the amplification of microsatellites (Short tandem repeats, STR) and measurement of the peak heights of amplicons in the electropherogram. Currently, the QF-PCR deemed reliable, fast, and inexpensive method that is gradually replacing conventional cytogenetic analysis of aneuploidy (examination of long-term cultures of amniotic fluid). However, in certain cases it is impossible to determine the parental origin and meiotic aneuploidy by QF-PCR. The aim of this work was to verify the new dinucleotide STR markers on chromozomes 13, 16, 18, 21, and 22 and further increase the diagnostic efficiency of QF-PCR retaining other STR markers on chromozome 15, 16, 22 and to determine the population and the analytical characteristics of these markers. For all dinucleotide STR markers stutter occurred in high frequency and therefore there were found not to be suitable for routine diagnostics. STR markers for chromozomes 15, 16 and 22 were tested on 100 patients. We selected four informative markers for both chromozome 16 and 22, and three markers for chromozome 15. Thus, I expanded set of diagnostic STR markers in this thesis.
