Project description:Myasthenia gravis (MG) is a relatively rare autoimmune neuromuscular disorder. Monozygotic twin studies indicate that discordance rate in MG is about 70-60%, suggesting that despite identical DNA unknown factors contribute to disease development. The aim of the current study was to identify novel disease-associated genes in purified monocytes, including both genes associated with predisposition or with disease course, using the unique model of MZ twins. Thus the transcriptome and methylome were compared between twins discordant and concordant for the diseases, as well as MG singletons, and healthy controls. Several transcripts associated with immune homeostasis and inflammation resolution were highlighted in the current study. High similarity between the healthy and the MG discordant twins found, suggest that genetic predisposition may have a stronger contribution then previously assumed. In addition, results suggest that numerous small changes in expression and DNA methylation might contribute to disease onset making it more difficult to pick up

Project description:Genome wide DNA methylation profiling of Rett syndrome monozygotic twins. The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles in primary skin fibroblast cells from Rett syndrome monozygotic twins.
Project description:Genome wide DNA methylation profiling of Rett syndrome monozygotic twins. The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles in primary skin fibroblast cells from Rett syndrome monozygotic twins. Bisulphite converted DNA from the 2 samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip
