Now that Siamese cats are available as genetic models for Niemann-Pick disease, in-depth studies on the biochemical properties of the disease are being performed. Previously, studies on Niemann-Pick disease were performed on rodents with drug-induced enzyme deficiencies, which was less than ideal. Although there are obstacles to be faced, researchers are optimistic that Siamese cats will speed the search for a cure or effective treatments for Niemann-Pick disease.
