Large Study Reveals Details of African American Genetic Ancestry

Published by ErinC under news

As shown in these ancestry paintings from 23andMe, the proportion of African DNA can vary widely for African Americans.
A recent study led by Carlos Bustamante of Cornell and Sarah Tishkoff of the University of Pennsylvania has shown that genetically speaking, African American can mean a lot of different things.
The researchers and their co-workers analyzed DNA [...]

SNPwatch: Genetic Clues to Bowel Disease Found in Mice and Men

Published by SatyaS under SNPwatch, news

Inflammatory bowel disease (IBD), which can appear as either ulcerative colitis or Crohn’s disease, damages the lining of the digestive tract and leads to abdominal cramps, incomplete digestion and nutritional deficiencies.
Previous research on IBD gave researchers reason to suspect that the CD39 gene, which is involved with inflammatory responses and immunity, may play a role [...]

SNPwatch: Genetic Variation In Morphine Receptor May Play A Part In Coping With Social Rejection

Published by ErinC under SNPwatch

SNPwatch gives you the latest news about research linking various traits and conditions to individual genetic variations. These studies are exciting because they offer a glimpse into how genetics may affect our bodies and health; but in most cases, more work is needed before this research can provide information of value to individuals. For that [...]

New Study Argues For Construction of Mexican Medical Genetic Reference Database

Published by MikeM under news

Mexican flu virus genetics has been much in news lately; how about a look at Mexican human genetics for a change? A new article from researchers at Mexico’s National Institute for Genomic Medicine (INMEGEN) examines genetic diversity across the nation, and argues that, in order to conduct studies of common genetic diseases efficiently, a Mexico-specific genetic reference database should be [...]
