Využití nových genomických technik ve studiu patogeneze vybraných vzácných dědičných onemocnění. / Application of novel genomic techniques in studies of pathogenesis of selected rare inherited disordersNosková, Lenka January 2013 (has links)
Rare diseases are a heterogeneous group of disorders. Knowledge of their molecular basis is poor and till recently there were no appropriate methodical approaches due to a limited number of patients. Novel genomic techniques, especially the DNA array technology and the next generation sequencing emerging in last few years, enabled studies of these diseases even in small families and sporadic cases. This PhD thesis focuses on application of novel genomic techniques in studies of rare inherited diseases. It describes a use of DNA array technology in linkage analysis, analysis of differential gene expression, analysis of copy number variations and homozygous mapping, and a use of next generation sequencing technology. Combination of these methods was used for identification of molecular basis of adult neuronal ceroid lipofuscinosis, Rotor syndrome, isolated defect of ATP synthase and mucopolysaccharidosis type IIIC.

Studium molekulární podstaty vybraných dědičně podmíněných onemocnění / Molecular basis of selected inherited rare diseasesHartmannová, Hana January 2013 (has links)
Rare diseases represent a clinically and genetically heterogeneous group of diseases affecting various organs and presenting at different ages. Identification and functional characterization of genetic defects causing individual rare diseases represent unique opportunity to understand biological functions of human genes and gene products as well as to basic pathogenetic mechanisms of individual diseases. This knowledge is prerequisite for their effective diagnosis, specific treatment and prevention and it also opens up an avenue for better understanding of complex diseases. My thesis documents basic conceptual and methodological developments of biochemical genetics, functional cloning, genetic mapping, positional cloning, DNA microarrays and genomic sequencing, which have provided a universal framework for effective characterization of the genetic architecture of almost all human diseases. This conceptual and technological developments are demonstrated on several cases of rare genetic diseases - adenylosuccinate lyase deficiency, mucopolysacharidosis type IIIC, Rotor syndrome, deficiency of ATP synthase, neuronal ceroid lipofuscinosis, GAPO syndrome and X -linked restrictive cardiomyopathy, which genetic and molecular basis I have helped to elucidate.

Současné metody analýzy genomu a jejich využití v hledání genetických příčin nemocí / Current methods of genome analysis and their use in identification of genetic determinants of human diseasesStránecký, Viktor January 2015 (has links)
The study of rare genetic diseases presents unique opportunity to uncover the genetic and molecular basis of human traits and greatly helped to the identification of genes, to the elucidation of their function and to the characterization of metabolic pathways and cellular processes. Over the past decades, linkage analysis has been appropriate approach to search for the genes causing Mendelian diseases and contributed to the identification of many genes, but the genetic cause of many diseases remains unknown. New methods of studying the human genome, microarray technology and massively parallel sequencing (next generation sequencing), represent a way to efficiently identify the cause of genetically determined diseases, based on direct observation of mutations in the genome of affected individuals. These techniques replaced the traditional method of disease gene identification represented by linkage analysis and sequencing of candidate genes and have become the standard approach to elucidate the molecular basis of diseases. In this work, i describe the the results achieved by using these methods - identification of the genes underlying mucopolysacharidosis type IIIC, isolated defect of ATP synthase, Rotor syndrome, autosomal dominat ANCL and GAPO syndrome.
