Is DNA dating destiny?
Last week’s post
dealth with three very serious applications of DNA testing. But not all DNA testing is to detect health-threatening conditions.
“Born to Run? Little Ones Get Test for Sports Gene,” ran the headline on the front page of the New York Times
, above an arresting image of a preschooler having his mouth swabbed for DNA. It’s from 2008, but remains a classic: I still assign it.
The sports gene company
is apparently still around and still testing for variants in just one gene: ACTN3. Two copies of the R577X variant indicate inborn skill at endurance events, and no copies suggest a child stick to sprints. The lucky heterozygotes might excel at both! Never mind that a child has some 20,000 or so other genes affecting physiology.
DISSECTING A DNA DATING WEBSITE
The most damage a sports gene test can do is to keep a child from doing something she loves because of a DNA-obsessed parent. A more questionable application of DNA testing is as part of “relationship science,” something I learned about a few weeks ago when a reporter from healthline.com
asked me about it. (more…)

In recent weeks, there’s been talk of three types of genetic testing transitioning from targeted populations to the general public: carrier screens for recessive diseases, tests for BRCA cancers, and non-invasive prenatal testing (NIPT) to spot extra chromosomes in fetuses from DNA in the maternal bloodstream.
Are these efforts the leading edge of a new eugenics movement? It might appear that way, but I think not.
When I began providing genetic counseling 30 years ago at CareNet, a large ob/gyn practice in Schenectady, NY, (more…)

The urine of a person with alkaptonuria turns dark upon standing.
When I read the headline of a recent press release
– "A new cause of osteoarthritis identified by research on a rare disease" -- I was drawn to "rare disease," even though I actually have osteoarthritis. And when I read “alkaptonuria," I was catapulted back more than a century to the first description of an "inborn error of metabolism.” (more…)

The many guises of CF.
A skinny little boy, with mocha skin and curly black hair, lived in the apartment building next door when I was growing up in Brooklyn in the 1960s. He didn’t live long enough to go to kindergarten. He had cystic fibrosis.
Today’s tots with CF face a far brighter future. A recent report in the Annals of Internal Medicine
applied trends in survival from 2000 to 2010 to project life expectancy for children diagnosed in 2010: 37 years for girls and 40 years for boys. (The difference may reflect hormones or the extra creatinine in the more muscular male of the species.) Factoring in the current rate of treatment improvements gives a soaring median survival of 54 years for women and 58 years for men when those kids grow up! (more…)

Emmanuel Gokpolu is my African "son," living in the midst of the Ebola crisis in Monrovia, Liberia.
(An updated version of this post appears at my Public Library of Science blog DNA Science
“That’s not Ebola!” I said to the vendor standing beside a display of boxer shorts festooned with pathogens, at a National Association of Biology Teachers conference a few years ago.
“No, that’s Ebola. Read the tag.”
“The tag’s wrong. It’s influenza. See the spokes on the surface? Ebola looks like a long soup ladle.”
He didn’t believe me, but the website was corrected a few months later. I still have my faux Ebola shorts somewhere.
JUST 7 GENES
The stark seeming-simplicity of the Ebola virus flashes across my mind whenever I get email from Emmanuel, a medical student in Liberia. My husband and I have been supporting his education since he contacted me in 2007 after reading Human Genetics: Concepts and Applications
, my textbook very soon to be published in its 11th edition. The story of our relationship, today between two families, is here
, but since then Eman has become a father, naming his son after my husband Larry.
Eman is our son in the African sense, not based on DNA. Escalating panic pervades his emails of the past few days. Right now he has a high fever, headache, and diarrhea, but says it is "only typhoid, not to worry."
The electronic communication with our Liberian friend is odd in the face of the crumbling infrastructure, the abandoned hospitals and schools. He taps on a phone, too terrified to enter an Internet cafe. And I’m mortified that the NBC nightly news placed a lengthy NASCAR crash report before an Ebola update. Eman wants to know why the US didn’t pay attention until the arrival here of two white, American patients. So do I. (more…)

William French Anderson, MD
In September 1990, William French Anderson, MD, posed with 4-year-old Ashi DeSilva at the NIH clinical center. Days earlier, she’d become the first recipient of gene therapy, a biotechnology that Dr. Anderson and others had been thinking about since Watson and Crick published the structure of DNA in 1953.
On July 29, 2004, Dr. Anderson, then 67, was arrested at his home in San Marino, California, and charged with molesting the daughter of a co-worker. The “inappropriate touching and medical exams” allegedly happened from 1997 to 2001, starting when the girl was ten. He has always maintained his innocence.
Dr. Anderson was tried in June 2006, convicted the next month, and sentenced to 14 years in prison on February 3, 2007. More than 200 scientists, many quite prominent, formed "Friends of French Anderson"
and sent detailed letters to the court vouching for his character. But despite appeals, he has been in prison all this time.
Out of options, Dr. Anderson has just unveiled a website, www.wfrenchanderson.org
that includes forensic evidence in his defense and other documents. He’s asked me to spread the word. I won’t discuss the evidence or legal details, at least not yet, but I wanted to relate how I came to learn about the case. (more…)

After a whirlwind of speaking at teachers' conferences this fall, in the springtime my audience will be high school students. I will be giving 4 keynote addresses for the New York State Student Convocation, for the March of Dimes. The talk is "Gene Therapy: A Forever Fix," which will coincide with a feature article I've written for Scientific American (print), March issue. The talk is based on my book, The Forever Fix: Gene Therapy and the Boy Who Saved It
The paperback version has an Instructor's Guide at the end, which is also posted on this website, beneath a handout for a classroom activity I've developed called "Putting a Face on Genetics."
Also check out my series on a clinic for genetic diseases among the Amish and Mennonites at my DNA Science blog at Public Library of Science (http://blogs.plos.org/dnascience/
The March of Dimes talks will be held at:
Hyde Park March 18
NYU March 26
Syracuse April 2
Staten Island April 24
I will post more details as I get them, or feel free to email me (firstname.lastname@example.org)

Hi everyone! Since last fall I've been blogging for Public Library of Science
, at http://blogs.plos.org/dnascience/
As you can see, I gave up cross-posting here on July 4 because through this site (Author's Guild) I have to type in all the html code, whereas PLOS uses an easy wordpress template. I got lazy. But not about blogging! So check out DNA Science at Public Library of Science. A new post every week, and I'm open to ideas and guest bloggers.
I always try to write about what everyone else misses.

Hugh and Bea Rienhoff (credit: Leah Fasten)
Genetics is the study of genes, DNA, and variation; heredity is the passing of inherited traits from parents to offspring. Families with one member, typically a child, who has a collection of unusual symptoms that don’t fit any clinical diagnosis may in fact have a genetic disease – but one that arose spontaneously in the child, rather than having been inherited from carrier parents.
Exome sequencing is helping to solve these genetics-but-not-heredity mysteries. The story of one little girl and her father’s efforts to find her mutant gene, and how the tale wove in and out and now back into my human genetics textbook
, illustrates the evolution of personalized genomic medicine.
THE BEA PROJECT
When Hugh Rienhoff first saw his daughter Bea, born in December 2003, he knew something was wrong. Her long feet, clenched fingers, poor muscle tone, widely-spaced hazel eyes, and a facial birthmark might have been just peculiarities to anyone who wasn’t also a physician and a geneticist. (more…)

Earlier today, my “in” box began to fill with info from everyone I’ve ever met letting me know that the Supreme Court
had ruled on the Myriad case about patenting the breast cancer genes BRCA1 and BRCA2. I also received a dozen pitches from PR people offering me all manner of instant interviews with lawyers, doctors, bioethicists, and health care analysts.
No one offered me an interview with a geneticist – a person who knows something about DNA. So being such a person myself, I decided to take a look at the decision. And I found an error right smack in the opening paragraph: (more…)
