Abstract
The development of sequencing technologies and their increased accessibility in clinical services and genetic laboratories have considerably accelerated the identification of genetic variants associated with rare diseases (RDs). Among these, Mendelian disorders of the epigenetic machinery (MDEM) are rare monogenic diseases characterized by the presence of mutations in genes encoding epigenetic regulators that play a key role in organismal development and cellular functions. Loss of function of these regulators is expected to lead to epigenetic modifications that profoundly affect genome expression and cellular identity. Disruptions in DNA methylation profiles have been documented in MDEMs, emerging as a useful diagnostic tool. The current challenge is to determine whether and how these epigenomic alterations drive the mechanisms underlying the clinical manifestations in patients suffering from this class of diseases. Studying MDEMs may therefore shed light on the important role of epigenetic information in health and disease, particularly the mechanisms involved in the development and understanding of complex pathologies, such as neurodevelopmental disorders and cancer.
期刊介绍:
m/s offers high-quality review articles in French, covering all areas of biomedical and health research, in a monthly magazine format (10 issues / year). m/s is read by the whole French-speaking community, in France but also in Belgium, Switzerland, Canada, Morocco, Algeria, Tunisia etc. m/s is not a primary publication, and thus will not consider unpublished data. Most articles are invited by the Editors, but spontaneous proposals are welcomed. Each issue combines news and views on the most recent scientific publications, as well as broadly accessible and updated review articles on a specific topic, and essays on science and society, history of science, public health, or reactions to published articles. Each year, m/s also publishes one or two thematic issues focused on a research topic of high interest. All review articles and essays are peer-reviewed.
