SERPINH1 Gene and Chromosome 8 in African-Americans

African-American female carriers of the SERPINH1 gene T-allele have a higher risk of premature delivery. The T-allele is associated with a decrease in the level of a protein that stabilizes collagen which is an important component of the amniotic sac.

This gene polymorphism was almost three times more common in premature babies born […]

Meeting with DNA Direct

Last Thursday, I had the chance to meet Jason Bobe and Lisa Lee of DNA Direct, a direct-to-consumer DNA testing company based in San Francisco. You may remember the DNA Direct ad running on Genetics and Health for a few weeks leading people to their blog (much to some people’s disapproval). I think […]

Genetics is a (Very) Good Thing

Results from a Wall Street Journal Online/Harris Interactive poll of 3,091 U.S. adults:
Have you ever had a genetic test to study your DNA?

Yes, have had a DNA test - 5%
No, have not - 95%

Those numbers will probably flip in 10 years.
Thankfully, 93% believe the science of genetics is “a good thing” or “very good thing.” […]

Genetics Interview #12: Dr. Marie Godfrey of Genetizen

The Genetics and Health interview series continues this week with Dr. Marie Godfrey, a fellow Johns Hopkins University alumna and author of Geneforum’s The Genetizen blog. Marie tends to be a little more cautious than me when it comes to embracing the genome revolution, but I think that’s good because we need to provide some […]

Weekly Genetics Quote #31: Corporate DNA

References to DNA surface in almost every context. This week’s genetics quote is from Corporate DNA: Learning from Life by Ken Baskin.
…Federal Express could integrate 100,000 people into a single corporate body by using information much the way our own bodies do. That is, the company made sure that its people, like all the […]

Gene Talk #9: Thought Experiments

Bryan Appleyard at Thought Experiments writes of Terrorists, Genes and Metaphors:
…The worst case of an uncontrolled metaphor was Richard Dawkins’ ’selfish gene’. No gene can be selfish nor can even appear to be acting selfishly, the word is quite meaningless. (For a full analysis of the damage done by this metaphor and its entirely unscientific […]

Genetics Interview #11: Trisha of Ideas for Women

This week, I interviewed Trisha of Ideas for Women for the Genetics and Health interview series. I can’t remember a time when I wasn’t passionate about science, health, and women’s issues so I’m especially pleased to see more blogs by intelligent women devoted to making our world a better place.
1. How did you […]

Multiple Genes for Autism

Kristina at Autism Vox scooped me on the latest study (drat my need to sleep!) to come out showing that autism is most likely due to more than one gene. Dr. Gerard Schellenberg says there may be four to six major genes and another 20 to 30 genes having a minor role. This isn’t […]
