Is your patient at increased risk for hereditary breast and ovarian cancer?

Compared to the general population, a woman with a confirmed BRCA1 or BRCA2 mutation is at greater risk of developing cancer during her lifetime—up to an 85% risk of breast cancer and up to a 40% risk of ovarian cancer. Her children, siblings and parents have a 50% chance of having the same autosomal dominant mutation and facing comparable risks. Learn more.

Abstract awarded a Best Poster designation by the American College of Cardiology at ACC.14

Testing a panel of 12 single-nucleotide polymorphims (SNPs) may help identify people at increased risk of atrial fibrillation and stroke, according to a recent study by researchers from the Lund University in Malmö, Sweden, the Broad Institute, Harvard Medical School, Cambridge, MA, and Quest Diagnostics. Individuals with the highest genetic risk scores based on the SNP panel had twice the risk of atrial fibrillation compared with those with the lowest scores, as well as a 23% greater risk of stroke. The preliminary results were presented in an award-winning poster at the 2014 Annual Scientific Session & Expo of the American College of Cardiology. ACC attendees may access poster #122 at the ACC.14 Attendee Portal.
