Researchers link sisters' paralysis to an 'extremely rare' genetic variant

Following a nearly 25-year search across three continents, parents of a pair of sisters -- who as children slowly became paralyzed from the waist down -- finally have a diagnosis. Thanks to a chance viewing on French TV of a story about another physically disabled child who regained her mobility after being diagnosed at TGen, the parents of the two sisters contacted TGen, hoping to end their decades-long diagnostic odyssey.
