In a new theoretical study, 23andMe, the personal genetics company, developed a mathematical model which shows that family history and genetic tests offer different strengths. The study results suggest that both family history and genetics are best used in combination to improve disease risk prediction. The full results of the study have now been published online in the journal PLOS Genetics. http://medicalxpress.com/news/2012-10-family-history-genetic-complex-disease.html Genetics Mon, 15 Oct 2012 16:39:42 EST news269537963 A new risk prediction tool can identify patients at high risk of coronary artery disease who might need further diagnostic work, says a study published on BMJ today. The tool is more accurate than existing models and could be easily integrated into electronic patient records or mobile applications. http://medicalxpress.com/news/2012-06-score-heart-disease-patients-chest.html Cardiology Tue, 12 Jun 2012 18:30:03 EST news258721759 Harvard School of Public Health (HSPH) researchers have found that detailed knowledge about your genetic makeup—the interplay between genetic variants and other genetic variants, or between genetic variants and environmental risk factors—may only change your estimated disease prediction risk for three common diseases by a few percentage points, which is typically not enough to make a difference in prevention or treatment plans. It is the first study to revisit claims in previous research that including such information in risk models would eventually help doctors either prevent or treat diseases. http://medicalxpress.com/news/2012-05-genetic-makeup-significantly-disease.html Genetics Thu, 24 May 2012 12:00:32 EST news257077685
