Experts say participants in genetic studies should be recontacted if results are reinterpreted 

A working group formed by a leading genetics organization is urging for participants in genetics research to be contacted when new findings suggest the results of their study need to be reinterpreted. The call is among a dozen recommendations issued by working group of the American Society of Human Genetics. The committee says scientists only need to try to recontact previous participants during the research funding period and that scientists needn’t go hunting for changes in genetic information. However, if new findings are expected to change how participants might be medically treated, the working group strongly encourages that researchers make reasonable attempts to get in touch with them. The recommendations were endorsed by eight international genetics organizations.
