DNA Methylation Patterns in patients with Neurodevelopmental Disorders
Vítková, Magdalena ; Steiner Mrázová, Lenka (advisor) ; Krejčík, Zdeněk (referee)
Neurodevelopmental disorders (NDDs) are diseases characterized by abnormal development of the central nervous system and brain. Simultaneously, the NDDs may also be associated with specific changes in DNA methylation. The rapid development of sequencing techniques, particularly whole genome sequencing (WGS) and whole exome sequencing (WES), has helped to uncover a number of genes associated with NDDs. Determining the pathogenicity of the variants found remains a challenge in the diagnosis of patients with NDDs. Finding the DNA methylation patterns by microarray or methylation sequencing in patients with NDDs carrying a variant of uncertain significance (VUS) may provide valuable information to address this problem. This thesis demonstrates the feasibility of using these approaches to functionally classify found variants in the KDM5C, ARID1B, ATRX, and BRWD3 genes. The aim was to determine whether there are changes in the DNA methylation patterns of patients with NDDs compared to probands and healthy controls, which could be used to confirm the diagnosis. Key words: DNA methylation patterns, DNA methylation, histone modifications, NDDs, KDM5C, ARID1B, ATRX, BRWD3
