At the milder end of the spectrum are individuals historically diagnosed with Niemann-Pick disease type B, a later-onset, chronic visceral form, characterized by progressive visceral organ symptoms including hepatosplenomegaly and pulmonary insufficiency, and survival into adulthood. In addition, some affected individuals present with an intermediate phenotype, Niemann-Pick disease type A/B."
