SMA type Type 1 Age of onset Birth to 6 months Symptoms Low muscle tone Lack of reflexes Inability to roll over or sit up unsupported Trouble breathing and swallowing Scoliosis Prognosis Without a disease-modifying treatment, children often do not survive past age 2.How is SMA type 1...
As a result, SMA disease prognosis depends on how many copies of SMN2 are present. Two or fewer copies of SMN2 leads to earlier onset, more severe disease, while three or more copies provide enough function to result in a later-onset, milder form of SMA. “It...

Type II SMA patients mostly had no homozygous deletion of NAIP and 2 copies of SMN2. However, patients with N3 genotype (> 1 copy of NAIP and 3 copies of SMN2) and patients with D3 genotype (0 copies of NAIP and > 3 copies of SMN2) had type III SMA. Conclusion SMN2 and NA...
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 ...
Another study has shown that NAIP deletion is significantly related to the clinical severity of SMA and is a marker for prediction of SMA prognosis16. This finding has also been confirmed in our study, since all patients carrying deletion of two copies of NAIP gene had severe (type I) SMA...

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 treated with SMN-directed therapies; Type 2 p...
