SNPwatch: More Genetic Variations Linked to AMD, a Leading Cause of Vision Loss

Age-related macular degeneration (AMD) is the most common cause of irreversible vision loss in the western world among people over 60. The two forms of the disease – wet and dry – both cause vision loss by destroying cells in the central portion of the retina. In the last few years, progress in ...

DNA Day is Coming Soon!

DNA Day was created in 2003 by concurrent (Senate and House) congressional resolution to celebrate two important milestones in the study of genetics: the 50th anniversary of the description of the double-helix structure of DNA by James D. Watson and Francis H.C. Crick and the completion of the Human ...

SNPwatch: Three New Genetic Variants Associated with Brain Aneurysm Identified

An aneurysm occurs when the wall of a blood vessel weakens and balloons outward, making the blood vessel abnormally large. The larger the vessel becomes, the greater the risk of rupture — a serious emergency. Often there are no symptoms of an aneurysm until a rupture occurs. Brain (also known as intracranial) ...

Genetics: Looking Back and Looking Forward

The tenth anniversary of the completion of the first draft of the human genome is approaching, apparently putting a lot of scientists in the mood for reflection on the past and speculation about the future of genetics. The journal Nature has a series of opinion articles and two news articles on the ...

23andMe’s New and Improved Maternal Haplogroups

It's springtime for 23andMe's Maternal Line tree! Each one of us can trace our ancestry back through our mother, our mother's mother, her mother, and so on. And there is one piece of our DNA that has been inherited along that exact, maternal line. By examining mutations in this segment of DNA, called ...

SNPwatch: Believe It Or Not, Researchers Find Genetic Variant Linked To Gullibility

We’ve all fallen for a prank at some point or another – whether it be “hey, your shoe’s untied” or getting surprised at your birthday party after your friend asks you to “just pick up something from the house.” Most people become more wary as they get older but other people manage to remain fundamentally ...

Malaria Parasite May Have Found Way To Thwart Protective Genetic Variation

Each year at least 350 million people around the world are infected by malaria parasites.  More than one million people, mainly young children, succumb to the disease.  But these numbers would be even higher if it weren’t for genetic adaptations that have evolved in populations living in areas where malaria ...

Analysis of Ancient DNA Suggests A Previously Unknown Type of Extinct Human Ancestor

Denisova cave from the outside. / Bence Viola. DNA isolated from a tiny bone fragment from the finger of a being that walked the earth between 30,000 and 50,000 years ago has possibly added a new branch to the human family tree. The piece of bone was found in the Denisova Cave in the Altai Mountains, ...

SNPwatch: Researchers Identify Genetic Variation That Contributes to Skin Color Differences in East Asians

From rich brown to almost translucent white, human skin colors span a remarkable spectrum. The evolutionary story of how we came to be such a varied species skin color-wise began around 40,000 years ago when the human groups that had left Africa and spread out along the southern coast of Asia began to move ...
