When her baby started struggling to breathe, Stella Praveen had a terrible feeling that something was gravely wrong with her 14-month-old daughter, Ellen.

Two weeks later, Praveen learned that her daughter, who had never been able to lift her neck nor roll over, was suffering from spinal muscular atrophy, a rare condition often fatal by age 2.
