SMN2 mis-splicing increases during late-stage disease, likely accelerating disease progression. Systemic ASO injection in adult mice causes peripheral SMN2 mis-splicing and affects prognosis, eliciting marked liver and heart pathologies, with decreased IGF1 levels. ASO dose鈥搑esponse and time-course...
The prognosis for patients with the disease – similar to motor neurone disease in adults – is not good, with some given a life expectancy of only two years. But 14-year-old Saeed has battled bravely through the condition – resorting to a wheelchair full-time only three years ago. ...
“They want to treat the worst condition instead of the bad one.” Atchison’s challenge was to have the insurance company understand that, while Logan didn’t have the very worst prognosis, he would still face significant issues if he didn't get SMA gene therapy as a newborn. “My bigg...
(Adult onset). Of the prevalent population, approximately 80% of the patients are characterized as Type 2 and Type 3. Life expectancy and disease severity vary by type of SMA. Type 1 patients have the worst prognosis, with a life expectancy of no more than two years unless ...
About SMA: SMA is a terminal, degenerative genetic disease that impacts the voluntary muscles in infants and children, including the ability to walk, sit, stand, eat, breathe, and even swallow, while cognitive ability is never affected. Ninety percent of children born with SMA die before the ...
Beyond funding for SMA, Team GSF has also raised much needed awareness of SMA, its shocking statistics, its brutal progression, and its dire prognosis. “To say we’re humbled by what the thirty inspiring Team GSF Santa Barbara Marathon runners have accomplished would be an enormous ...
