Maternal, paternal genes’ tug-of-war may last well into childhood
An analysis of rare genetic disorders in which children lack some genes from one parent suggests that maternal and paternal genes engage in a subtle tug-of-war well into childhood, and…

International study identifies gene variants associated with early heart attack
The largest study ever completed of genetic factors associated with heart attacks has identified nine genetic regions — three not previously described — that appear to increase the risk for early-onset myocardial infarction. The report from the Myocardial Infarction Genetics Consortium, based on information from a total of 26,000 individuals in 10 countries, was given…
