False-positive prenatal genetic tests studied
Health Canal

This finding is reported April 1 in the New England Journal of Medicine. The article is part of a collection of papers examining screening tests now available to patients due to recent advances in genome sciences.

Breast cancer genes: How much risk do BRCA mutations bring?
LiveScience
Women with mutations in the BRCA1 and BRCA2 genes are at increased risk for breast and ovarian cancer, but a woman's exact cancer risk may vary greatly depending on exactly how her gene is mutated or changed from its original form. A new study identifies a number of mutations in the BRCA1 and BRCA2 genes that may help doctors provide women with more precise estimates of their cancer risk.

Blood test for lung cancer as 1st-line screen before LDCT
Medscape
The use of low-dose CT as a screening tool for lung cancer has been criticized for its high cost and its feasibility, given the large number of long-time heavy smokers and ex-smokers and the complexity of the process. What if a less expensive and more easily administered test could refine who is at highest risk for lung cancer, and therefore identify the top candidates for low-dose CT?

New Ebola study points to potential drug target
Washington University in St. Louis via Infection Control Today
Opening the door to potential treatments for the deadly Ebola virus, scientists have found that a protein made by the virus plays a role similar to that of a coat-check attendant. The protein removes a protective coat from the genetic material, exposing the viral genome so that it can be copied, and then returns the coat, according to a new study led by scientists at Washington University School of Medicine in St. Louis.
