The research was published today, 25 January, in the journal Science. http://medicalxpress.com/news/2013-01-epigenetic-reprogramming-inherited.html Genetics Thu, 24 Jan 2013 14:00:07 EST news278258273 The causes of autism and autism spectrum disorder (ASD) are complex, and contain elements of both nature (genes) and the environment. New research published in BioMed Central's open access journal Molecular Autism shows that common genetic polymorphisms (genetic variation) can add up to an increased risk of ASD. http://medicalxpress.com/news/2012-10-adding-autism.html Autism spectrum disorders Mon, 15 Oct 2012 05:25:02 EST news269497423 (Medical Xpress) -- A study published in Genes and Development from scientists at the Friedrich Miescher Institute for Biomedical Research pinpoints the importance of maternal epigenetic influences during early embryogenesis in mammals. A chromatin regulatory complex in the oocyte ensures that the proper luggage of maternal transcripts and chromatin structures control the first steps in the formation of an embryo. In the absence of this epigenetic regulator the embryo fails to develop correctly. http://medicalxpress.com/news/2012-05-mother-maternal-epigenetic-inheritance.html Genetics Mon, 07 May 2012 08:58:44 EST news255599878 While genetic inheritance is known to play a role in the multifactorial development of most diseases of the heart, there are also a number of clearly diagnosed cardiac conditions which owe their development to quite specific genetic abnormalities. When these genetic disorders affect the integrity of the heart's muscle they are known as a "cardiomyopathy"; when the disorder affects the heart's "excitability", it is known as a "channelopathy". http://medicalxpress.com/news/2011-06-genetic-inherited-cardiac-conditions-patchy.html Cardiology Mon, 27 Jun 2011 03:28:24 EST news228364086
