Dataset Information


High-specificity bioinformatics framework for epigenomic profiling of discordant twins reveals specific and shared markers for ACPA and ACPA-positive rheumatoid arthritis.

ABSTRACT: Study of changes in DNA Methylation in monozygotic Rheumatoid Arthritis discordant twins and ACPA+/- discordant twins Overall design: Five healthy twin pairs discordant for presence of antibodies to citrullinated protein antigens (ACPA). Secondly, profiling seven twin pairs discordant for ACPA-positive RA.

Twin studies are powerful models to elucidate epigenetic modifications resulting from gene-environment interactions. Yet, commonly a limited number of clinical twin samples are available, leading to an underpowered situation afflicted with false positives and hampered by low sensitivity. We investigated genome-wide DNA methylation data from two small sets of monozygotic twins representing different phases during the progression of rheumatoid arthritis (RA) to find novel genes for further researc  ...[more]
