Molecular genetic analysis of rare ocular disorders in Roma population from the Czech Republic
Rysková, Natálie ; Lišková, Petra (advisor) ; Klímová, Aneta (referee)
The Roma are the largest and most widespread transnational ethnic community. The Czech Republic estimates their 2% representation in its population. Due to the high level of endogamy, the spectrum and frequency of hereditary diseases in the Roma population differ from the majority population. Hereditary eye diseases are one of the most common causes of blindness in younger adults and thus represent a real socio-economic burden. The aim of the thesis was to perform molecular genetic analysis in individuals of Roma origin suffering from hereditary diseases affecting vision, including dual impairments and syndromes, and to determinate the frequency of the detected pathogenic variants in this population. Molecular genetic analysis of 17 families was performed using direct and whole exome sequencing. Within the framework of an international collaboration, the degree of their mutual kinship was calculated using the PLINK program. The frequency of selected variants was determined in a control dataset comprising 156 Roma exomes and genomes. The spectrum of analyzed diseases included various retinal dystrophies, primary congenital glaucoma, Usher syndrome, neuronal ceroid lipofuscinosis, Noonan syndrome, nanophthalmos and congenital cataract, facial dysmorphism and neuropathy. The results of the thesis...
