Molecular genetic approaches used in preimplantation genetic analysis of human embryos in assisted reproduction
Limbergová, Jana ; Machoň, Ondřej (advisor) ; Šimoník, Ondřej (referee)
Preimplantation genetic testing is one of the main clinical procedures that take place in assisted reproduction centres around the world. It is sought after by couples for many different reasons. The causes of problems may relate to hereditary diseases that potential parents do not wish to pass on to their offspring, or may include the risk of transmission of chromosomal alterations. In addition, infertility may be caused by an increased risk of embryo aneuploidy, which correlates with mother's increased age and other factors that this bachelor thesis discusses. The bachelor thesis also focuses on up-to-date approaches to cytogenetic examinations for reproductive genetics and discusses recent clinical molecular methods that are used to improve the diagnosis and therapy of infertile couples. These are, for example, microarray methods, quantitative real-time PCR or next-generation sequencing and methods of whole-genome amplification. This work also summarizes methods that are gradually being abandoned, e.g. fluorescent in situ hybridization, and compares their advantages and disadvantages. Key words: preimplantation genetic testing, aneuploidy, structural rearrangements, monogenic diseases, biopsy, fluorescent in situ hybridization, microarray methods, comparative genomic hybridization, quantitative...
