Manny: Hoping new research helps others with sickle cell disease
Emmanuel “Manny” Johnson, Jr., shares many loves with his little brother, Aiden — from basketball to video games. One thing he wishes they did not share is sickle cell disease (SCD), so Manny is playing a role in a new effort to improve treatment for patients like 7-year-old Aiden, himself and others living with the inherited blood disorder. ...

Reviving fetal hemoglobin in sickle cell disease: First patient is symptom-free
Manny Johnson of Boston, 21, previously required monthly blood transfusions to keep his severe sickle cell disease under control. After receiving a new gene therapy treatment, he’s been symptom-free for six months. Researchers at the Dana-Farber/Boston Children’s Cancer and Blood Disorders Center reported Manny’s case Saturday at the American Society of Hematology meeting in San Diego. Manny ...

Sickle cell gene therapy to boost fetal hemoglobin: A 70-year timeline of discovery
Boston Children’s Hospital is now enrolling patients age 3 to 35 in a clinical trial of gene therapy for sickle cell disease. Based on technology developed in its own labs, it differs from other gene therapy approaches by having a two-pronged action. It represses production of the mutated beta hemoglobin that causes red blood cells to ... Read More about Sickle cell gene therapy to boost fetal hemoglobin: A 70-year timeline of discovery
Gene therapy halts progression of cerebral adrenoleukodystrophy in clinical trial
Adrenoleukodystrophy — depicted in the 1992 movie “Lorenzo’s Oil” — is a genetic disease that most severely affects boys. Caused by a defective gene on the X chromosome, it triggers a build-up of fatty acids that damage the protective myelin sheaths of the brain’s neurons, leading to cognitive and motor impairment. The most devastating form of the ... Read More about Gene therapy halts progression of cerebral adrenoleukodystrophy in clinical trial
Landmark moment for science as the FDA approves a gene therapy for the first time
Today, the Food and Drug Administration approved a gene therapy known as CAR T-cell therapy that genetically modifies a patient’s own cells to help them combat pediatric acute lymphoblastic leukemia (ALL), the most common childhood cancer. It is the first gene therapy to be approved by the FDA. “This represents the progression of the field of gene ...

BCL11A-based gene therapy for sickle cell disease passes key preclinical test
Research going back to the 1980s has shown that sickle cell disease is milder in people whose red blood cells carry a fetal form of hemoglobin. The healthy fetal hemoglobin compensates for the mutated “adult” hemoglobin that makes red blood cells stiffen and assume the classic “sickle” shape. Normally, fetal hemoglobin production tails off after birth, shut ... Read More about BCL11A-based gene therapy for sickle cell disease passes key preclinical test
Wine used to toast CGD gene therapy trial linked to decades-long scientific journey
When Brenden Whittaker of Columbus, Ohio, the first patient treated with gene therapy for chronic granulomatous disease (CGD), showed successful engraftment last winter, the gene therapy team lifted glasses for a celebratory toast. The wine they sipped was no ordinary wine. The 2012 Bordeaux blend came from an award-winning California vineyard owned and operated by Robert ...

Forty years waiting for a cure: ALD gene therapy trial shows early promise
A small piece of notepaper, folded twice, sits tucked in a slot of the secretary desk in the living room. Every so often, I pull it out, read it, then reread. Addressed to my mom, the paper has a question and two boxes, one “yes” and one “no,” written with the careful precision of a ...

Gene therapy restores hearing in deaf mice
More than 70 different genes are known to cause deafness when mutated. Jeffrey Holt, PhD, envisions a day when patients with hearing loss have their genome sequenced and their hearing restored by gene therapy. A proof-of-principle study published today by the journal Science Translational Medicine takes a clear step in that direction, restoring hearing in deaf mice. “Our gene ...

Gene therapy gets in the ring with another disease
Seeing that his mother, Kadriye, wasn’t looking, Emir Seyrek got an impish grin on his face, the kind only a two-year-old can have. He quietly dumped his bowl of dry cereal out on his bed and, with another quick look towards his mother, proceeded to pulverize the flakes to dust with his toy truck. The ...
