Genetic material has been analyzed from members of a large Swiss family, the majority of whom suffered from auto-somal dominant juvenile cataract. From the DNA, researchers at ETH Zurich and the University Zurich identified the chromosomal location and exact molecular defect in the coding region of the gene responsible for the type of childhood cataract. Until now, no […]

Over the past two years here at Genetics and Health, I’ve written almost 1,200 posts and received over 2,000 posts comments all on genetics, genes, the genome, and DNA. Having the opportunity to write about my lifelong passion is a dream come true. So that I can improve and grow as a genetics blogger, writer, […]

A Florida bill to require DNA testing of pregnant girls under the age of 14 has been voted down. The bill would have asked doctors, nurses, and other healthcare workers (including abortion providers) to collect DNA from the girl and her fetus for the purpose of identifying the father for prosecution. Sex with minors under […]

My vacation has thus far not included a spa visit, but if I ever do make it to one again in my lifetime, I might be tempted to find one that offers DNA testing. More in the New York Times:
It is possible to get many things at the Four Seasons Hotel in Westlake Village, […]

Knowing more about your risk of type 2 diabetes is just a keyboard click away at DNA Direct. Together with deCODE diagnostics, DNA Direct is now offering deCODE T2, a genetic test that examines the presence of the “T” allele of SNP rs7903146, located within the transcription factor 7-like 2 (TCF7L2) gene. Almost twice as […]

Yesterday, I joked around about setting my DNA sequence to music. It’s not as crazy as you might think. Dr. MA Clark has done just that with some well known DNA sequences. Here’s genetic music based on SRY, the male determining factor.

Biotech start-ups utilizing genetic information are nothing new. Could 23andMe be unique? Yesterday, I received a nice email from their recruiting manager, Oliver Ryan. As luck would have it, I’m vacationing in the San Francisco Bay Area and hope to swing a meeting with some 23andMe folks next week, including Anne Wojcicki and Linda Avey. […]

Stanford Magazine (May/June 2007) asks, What’s the next step in human evolution?
Luigi “Luca” Cavalli-Sforza, professor emeritus of genetics, is a pioneer in “genetic geography,” a field that uses DNA to help understand human migration throughout history.
…A major genetic change which started already some centuries ago, with the navigation of the oceans, and is becoming faster now, […]

DNA is being collected from birth. In Minnesota, blood samples are collected from all newborns unless parents specifically request an exemption. But, these samples cannot be used for research or any other reason not related to disease testing unless the parents sign consent forms.
Genetic privacy advocates think that no blood samples should be taken at […]

Isaac Owusu had no idea what was in store when he decided to take a DNA test to bring his four sons to the US from Ghana. As I wrote last summer, immigrants are increasingly being asked by the US government to prove their family relationships using DNA. But Isaac, a new US citizen, had […]
