A decade and a half after a series of tragic setbacks led to critical reevaluations, scientists say gene therapy is ready to enter the clinic
The spleen is a very unappreciated body part. The Talmud considered it the “organ of laughter,” whereas the ancient Greeks equated it with melancholy.
You have your genome or exome (the protein-encoding part) sequenced to help diagnose a puzzling set of symptoms, and something totally unrelated, and unexpected, turns up – a so-called “incidental finding.”Surprises, of course, aren’t new in medicine.
Exomes are big news. Sequencing of the protein-encoding part of the genome is increasingly solving medical mysteries in children. It began with Nicholas Volker and his recovery from a devastating gastrointestinal disease with a stem cell transplant once his exome sequence revealed his problem.And my recent Medscape assignments reveal the trend: 7 of 12 kids’ exomes leading to diagnosis at Duke University (from May 10, 2012); whole genomes of 5 infants from the neonatal intensive care unit at Children’s Mercy Hospital and Clinics in Kansas City, Missouri (from October 3), in just 50 hours each, focusing on 600 single-gene diseases; and 300 patients at the Whole Genome Laboratory at the Baylor College of Medicine, with 300 more waiting -- 85% of them kids (from November 9, 2012).But wait.
Gene therapy, once off to a rocky start, transforms medicine by getting at the root cause of many diseases
The young couple looked at me expectantly as I re-read the amnio report and tried to decide what to tell them.“The ultrasound from 15 weeks looks fine,” I stalled, trying to present the good news first.“What about the amnio?”“Well, there is something unusual.

Gregor Mendel in textbooks: should he stay or should he go now? (Credit: Natl Library of Medicine) Summer reading for most people means magazines, novels, and similar escapist fare, but for me, it’s the American Journal of Human Genetics (AJHG).
On Sunday morning, July 21, I faced a room of people from families with Leber congenital amaurosis (LCA), an inherited blindness caused by mutations in any of at least 18 genes.
Will a DNA test today yield unwanted information tomorrow? My mother-in-law’s arms look like she’s been in a fight. The bruises don’t hurt, but they’re embarrassing.
I’ve written about human stem cells from all sorts of sources, from human embryos circa 1997 (“Embryonic Stem Cells Debut Amid Little Media Attention,” The Scientist, too ancient for a link), to old people’s teeth.
Brain tumor cells, from Ignatova et al., Glia, 2002 I had a very strange week. While in Washington, D.C., writing news releases, for the Model Organisms to Human Biology: Cancer Genetics meeting sponsored by the Genetics Society of America, I had left, back home in upstate New York, my dear hospice patient.
When I wrote for The Scientist , I covered the debuts of several genome sequences – fruit fly, rat, pufferfish, and the plague bacterium, to name a few.
#StorySaturday is a Guest Blog weekend experiment in which we invite people to write about science in a different, unusual format – fiction, science fiction, lablit, personal story, fable, fairy tale, poetry, or comic strip.
The pharmaceutical industry rightly calls the stage in drug development between basic research and clinical trials the “Valley of Death.” This is when a potential treatment that’s worked in mice, monkeys, and the like catapults to a phase 1 clinical trial to assess safety.
Sequencing of the exome – the protein-encoding parts of all the genes – is beginning to dominate the genetics journals as well as headlines, thanks to its ability to diagnose the formerly undiagnosable.The 2011 Pulitzer Prize in Explanatory Reporting honored the Milwaukee-Wisconsin Journal Sentinel’s coverage of a 4-year-old whose intestinal disorder was finally diagnosed after sequencing his exome.
I became a science writer, circa 1980, because I didn’t think flies with legs growing out of their heads – my PhD research – had much to do with human health or biology.
When cosmetic gynecologist Adam Ostrzenski, MD set out to discover the elusive G-spot, the part of a woman’s anatomy supposedly responsible for orgasm, he followed a flawed premise – but his finding announced today will undoubtedly generate frantic media coverage.The discovery of the G-spot in a lone elderly corpse and the lack of information on just what Dr.
In Fasil Tekola Ayele’s native Ethiopia, the people call it “mossy foot.” Medical textbooks call it podoconiosis, non-filarial elephantiasis, or simply “podo.”The hideously deformed feet of podo result not from mosquito-borne parasitic worms, as does filarial elephantiasis, nor from bacteria, like leprosy.
