Spinal Muscular Atrophy: Single-Dose Gene-Replacement Therapy

Last Updated on

The results were encouraging. As of the data cutoff on August 7, 2017, all 15 patients were alive and event-free at 20 months of age, as compared with a rate of survival of 8% in a historical cohort. In the high-dose cohort, a rapid increase from baseline in the score on the CHOP INTEND scale followed gene delivery, with an increase of 9.8 points at 1 month and 15.4 points at 3 months, as compared with a decline in this score in a historical cohort. Of the 12 patients who had received the high dose, 11 sat unassisted, 9 rolled over, 11 fed orally and could speak, and 2 walked independently. Elevated serum aminotransferase levels occurred in 4 patients and were attenuated by prednisolone.

The researchers concluded that in patients with SMA1, a single intravenous infusion of adeno-associated viral vector containing DNA coding for SMN1 resulted in longer survival, superior achievement of motor milestones, and better motor function than in historical cohorts. However, further studies are still necessary to confirm the safety and efficacy of this type of gene therapy.

  • Researchers find genetic links to child obesity across diverse ethnic groups August 22, 2019
    An international team of researchers who analyzed data across multiple ethnicities has produced the largest genetic study to date associated with common childhood obesity. The Early Growth Genetics (EGG) Consortium discovered a robust new signal, fine-mapped previously reported genetic variants, and added to evidence that genetic influences on obesity operate across the lifespan.
  • Researchers develop model to personalize radiation treatment August 22, 2019
    A personalized approach to cancer treatment has become more common over the last several decades, with numerous targeted drugs approved to treat particular tumor types with specific mutations or patterns. However, this same personalized strategy has not translated to radiation therapy, and a one-size-fits-all approach for most patients is still common practice. Moffitt Cancer Center […]
  • How our genes and environment influence BMI and height August 22, 2019
    Environmental conditions influence our body mass index (BMI) by increasing or decreasing the effect of inherited genetic variations, University of Queensland researchers have discovered.
  • Genetic testing and family tree research are revealing painful family secrets, research says August 22, 2019
    Genealogical research and genetic testing are revealing skeletons in family closets and causing rifts among members, a new study shows.
  • Researchers use single-cell sequencing to get a better look at human embryo implantation August 22, 2019
    A team of researchers affiliated with multiple institutions in China has used single-cell sequencing to learn more about the human embryo during implantation in the uterus. In their paper published in the journal Nature, the group describes sequencing thousands of human embryo cells from before, during and after implantation, and what they learned from it.
