Cardiomyopathies (CMs) are a very broad group of diseases, including genetically determined and acquired, and their classification is based on phenotypic characteristics. There is always a need to search for the etiology (often also to try to identify the genetic cause), which may determine the appropriate choice of clinical management. The geographical distribution of genetic variants varies as does the prevalence across populations, ethnic groups, regions, and countries.

The circulating methylome in childhood-onset inflammatory bowel disease.

J Crohns Colitis

October 2024

Translational Gastroenterology Unit, Nuffield Department of Experimental Medicine, University of Oxford, Oxford, UK.

The genetic contribution to inflammatory bowel disease (IBD) encompassing both Crohn's disease (CD) and ulcerative colitis (UC), accounts for around 20% of disease variance, highlighting the need to characterise environmental and epigenetic influences. Recently considerable progress has been made in characterising the adult methylome, in epigenome-wide association studies. We report detailed analysis of the circulating methylome in 86 patients with childhood-onset CD,UC and 30 controls using the Illumina Infinium Human MethylationEPIC platform.
