Opal Sandy was born into a world she could not hear. 

The British baby girl, now 18 months old, had a rare genetic condition called auditory neuropathy that interrupted nerve impulses that travel from the inner ear to the brain. She'd been fitted with a cochlear implant, but it could only help so much.

Then came a breakthrough gene therapy

    MONDAY, Nov. 13, 2023 (Healthday News) -- Two new gene-editing treatments that target dangerously high levels of cholesterol in people with a genetic predisposition to the condition were found safe and effective in new, groundbreaking research.

    While powerful drugs like statins can help manage cholesterol in most people, they can't treat those who have genes that predispose them to heart ...

    Gene therapy has restored mobility in mice with completely severed spinal cords, researchers report.

    The mice regained the ability to walk, with gait patterns resembling those of mice that resumed walking naturally after only partial cord injuries, the investigators found.

    This happened because the new gene therapy used techniques to not only repair spinal cord tissue, but also to d...

    A second human patient has received a genetically altered pig heart as he battles the ravages of end-stage heart disease.

    Millions of stray cats roam the world over, and surgical sterilization has long been the primary method of population control.

    But a small new study shows promising results for a one-and-done contraceptive injection.

    Researchers say this first-of-its-kind approach appears safe and effective.

    “A non-surgical contraceptive that could result in lifetime sterility following...

    An exceptionally pricey gene therapy cure for sickle cell disease could soon be available, but it's not clear whether insurance companies will balk at the cost and deny coverage.

    On the surface, the gene therapy does not appear as cost-effective as the grinding medical care that sickle cell patients now receive, according to a new analysis.

    Gene therapy applied just once to a sickle...

    SCID refers to a group of rare genetic diseases that cause babies to be born ...

    Patients with a high-risk bladder cancer now have a new option to treat it.

    The U.S. Food and Drug Administration on Friday approved a gene therapy called Adstiladrin, which is designed to work for patients who have what's called high-risk non-muscle-invasive bladder cancer (NMIBC) that hasn't responded to the standard treatment, Bacillus Calmette-Guérin (BCG), but hasn't spread. BCG is ...

    An experimental gene therapy that's applied as a skin gel appears to heal wounds caused by a rare and severe genetic skin disease.

    It'...

    Multiple sclerosis (MS) patients undergoing a treatment that depletes a type of immune cell that fuels MS attacks still have a strong response to mRNA COVID-19 vaccines, a new study finds.

    "The message from this study is clear -- it is worthwhile for patients with MS receiving [anti-CD20] treatment to get a COVID-19 vaccine, which will prevent severe illness," said researcher E. John Wher...

    A gene therapy aimed at freeing the heart's capacity for self-repair has shown early promise in an animal study.

    The study -- done in pigs -- found that the treatment approach was not only feasible, but also improved the animals' heart function after they sustained heart attack damage.

    There is a long way to go before a similar gene therapy could be applied to human heart attac...

    Doctors for the first time have used a form of gene therapy to restore partial vision in a blind person, according to findings announced Monday.

    An experimental gene therapy for Duchenne muscular dystrophy shows promise, a small study suggests.

    The severe form of muscular dystrophy -- which affects about one in 3,500 males born each year in the United States -- causes muscles to progressively weaken and lose the ability to regenerate after an injury.

    Muscle tissue is eventually replaced by fat and collagen. Many children wit...

    A pair of new gene therapies promise a potentially lasting cure for sickle cell disease by subtly altering the genetic information in patients' bone marrow cells, researchers report.

    Both therapies work by switching on a gene that promotes production of fetal hemoglobin, said Dr. Lewis Hsu, chief medical officer of the Sickle Cell Disease Association of America.

    Sickle cell dis...

    It may be possible to protect Parkinson's patients' brains from further damage by turning off a "master regulator" gene, researchers report.

    "One of the biggest challenges in treating Parkinson's, other than the lack of therapies that impede disease progression, is that the disease has already laid waste to significant portions of the brain by the time it is diagnosed," said researche...

    In a first, scientists have used gene-editing technology to create "designer" immune system cells that can fight tumors and survive for months in cancer patients' bodies.

    It's a proof of principle, the researchers say -- and an early step toward bringing the gene-editing tool known as CRISPR into cancer treatment.

    CRISPR allows researchers to precisely "snip" bits of DNA wit...

    Mosquitoes that can't be infected by or spread dengue virus have been created by scientists.

    "Designer babies" aren't going to be a reality anytime soon, researchers say.

    Concerns about genetically altering embryos to have desired traits have been around nearly as long as in vitro fertilization (IVF) and the technology to screen embryos have existed.

    But while recent live births resulting from embryonic CRISPR gene editing have re-focused attention on the issue, the...

    Last year, a scientist from China created a storm of controversy when he claimed he'd used gene-editing technology to create "designer" twin babies. Now, a new study is highlighting one of the dangers of that endeavor.

    Researchers have found that the gene mutation the scientist used -- affecting a gene called CCR5 -- is associated with a shorter life span: People who carry two copies ...

    A gene therapy that tweaks the immune system might offer hope to people with blood cancer that has resisted standard treatments, a new preliminary trial suggests.

    The cancer, called multiple myeloma, arises in certain white blood cells. It is currently incurable, but there are treatments that can help people live with the disease for years.

    However, most people eventually pr...

    They were once imprisoned in plastic bubbles that cut them off from the dangerous, infectious world.

    But now, children born with a disease that robs them of a functioning immune system may have gained a new lease on life.
