Optimization of newborn screening for cystic fibrosis in the Czech Republic
Krulišová, Veronika ; Macek, Milan (advisor) ; Vrtěl, Radek (referee) ; Hřebíček, Martin (referee)
Newborn screening for cystic fibrosis allows diagnosing patients with cystic fibrosis during asymptomatic stage of their disease or when the symptoms had not fully developed. Due to early diagnosis, patients with cystic fibrosis have the possibility to be treated prior to the occurrence of irreversible changes in the relevant organs, which leads to significantly improved quality of life and patient survival. Commented version of the doctoral thesis presents issues concerning the selection of a suitable newborn screening programme for cystic fibrosis in neonates born in the Czech Republic and establishes requirements for particular analytical and molecular genetics tiers in the tested screening schemes. The aim of this thesis is to nominate newborn screening protocol for cystic fibrosis that leads to optimal parameters in terms of its high sensitivity and specificity, including acceptable costs in the conditions of the Czech Republic health care system.

Molecular genetic diagnostics of cystic fibrosis, hyperhomocysteinemia-related disorders and male infertility: validation and application of high resolution melting
Norambuena Baraquet, Patricia Alejandra Del Pilar ; Macek, Milan (advisor) ; Jirsa, Milan (referee) ; Vrtěl, Radek (referee)
Diagnostic test results are crucial for treatment management and family planning of an individual. Considering that around 80% of medical decisions are based on diagnostic tests and that genotyping is usually concluded only once in a lifetime, it is of a great importance to assure highly accurate test results and provided under high quality standards. Cystic fibrosis (CF) is one of the most common and life-threatening autosomal recessive genetic disease affecting mainly Caucasian populations. CF is caused by mutations in the CFTR gene and until this date, more than 1900 mutations have been detected, while only few of them have frequencies higher than 1% worldwide. Thus, to confirm the diagnosis of cystic fibrosis in patients where only one disease-causing mutation has been found, it is necessary to apply a sensitive test to search for uncommon CFTR gene mutations/variants. In this work, we have successfully used HRM for gene scanning of certain exons of the CFTR gene. We have confirmed the numerous advantages of the HRM method for gene scanning and also detect some limitations that must be considered through an implementation process in a DNA diagnostic laboratory. Hyperhomocysteinemia has been proposed as a risk factor for several diseases such as recurrent pregnancy loss and inherited thrombophilia and...
