Expert discusses whether direct-to-consumer genetics testing kits really work
For my family this past holiday season, the most heated discussion was not generated from the usual suspects (politics or sibling dynamics), but rather from a Secret Santa gift: a 23andMe genetics testing kit given by an aunt to her niece. The kit's premise is that by sending in a saliva sample, you can find out how much of your DNA hails from different parts of the world.

Fragile X finding shows normal neurons that interact poorly

Accessing your own genomic data is a civil right but requires strategies to manage safety
The Genetic Information Nondiscrimination Act of 2008, or GINA, expanded individuals' access to genetic information by forcing changes to the Health Insurance Portability and Accountability Act (HIPAA) Privacy Rule. These amendments, finalized in 2013 and 2014, gave Americans a civil right to obtain copies of their own genetic test results stored at HIPAA-regulated laboratories. In a commentary published January 4 in the American Journal of Human Genetics, Barbara J. Evans, Alumnae College Professor of Law and Professor of Electrical and Computer Engineering at the University of Houston, describes how civil rights and safety concerns collided after these changes and offers strategies to reconcile the two.

In a milestone year, gene therapy finds a place in medicine
After decades of hope and high promise, this was the year scientists really showed they could doctor DNA to successfully treat diseases. Gene therapies to treat cancer and even pull off the biblical-sounding feat of helping the blind to see were approved by U.S. regulators, establishing gene manipulation as a new mode of medicine.

Aggression in childhood: Rooted in genetics, influenced by the environment
Over the past few months, many local cases of assault and harassment have come to light and been widely discussed in the news, both here and in the U.S. and Europe. Why do people have these types of aggressive impulses? To look for an answer, Stéphane Paquin, a PhD candidate in sociology at Université de Montréal working under the supervision of Éric Lacourse and Mara Brendgen, led a study on 555 sets of twins to compare incidences of proactive and reactive aggressive behaviour. His results demonstrate that, at age 6, both types of aggression have most of the same genetic factors, but the behaviour diminishes in most children as they age. Increases or decreases in aggression between the ages of 6 and 12 appear to be influenced by various environmental factors rather than genetics.

Researchers work to help children with a rare form of autism
Dylan started life as a typical baby, meeting his milestones for walking, talking, and other markers of normal development. In a home video from when Dylan was about 3, he climbs, bursting with energy, on the couch and pretends to read aloud from a picture book. His conversation is animated as he talks about the book with his father, who is recording, and he speaks in full sentences. In kindergarten, his parents noticed some language delays, and Dylan received special education support, but his mother, Kim Covell, saw him as "just a quirky kid."

Recordings reveal deep credibility gap when doctors and parents discuss outcomes for critically ill
An analysis of 16 audiotaped conversations between parents of infants in a neonatal intensive care unit (NICU) and clinicians found that medical staff routinely downplay quality of life issues and leave families more optimistic about their babies' prognoses than the clinicians intended.

In multiple myeloma, high levels of enzyme ADAR1 are associated with reduced survival
Multiple myeloma is the second most common blood cancer in the United States. Thirty to 50 percent of multiple myeloma patients have extra copies of the gene that encodes the enzyme ADAR1. Using a database of multiple myeloma patient samples and information, researchers at University of California San Diego School of Medicine found that high ADAR1 levels correlate with reduced survival rates. They also determined that blocking the enzyme reduces multiple myeloma regeneration in experimental models derived from patient cancer cells.
