Cirrhosis and liver failure: expanding phenotype of Acid sphingomyelinase-deficient niemann-pick disease in adulthood.

ABSTRACT: Acid sphingomyelinase-deficient Niemann-Pick disease (ASMD) includes the severe neuronopathic type A, the non-neuronopathic type B, and rare intermediate cases. Here we report on such an atypical type B patient who died at 31 years of age from liver failure. This male subject was first seen in a paediatric department at the age of 3 years because of significant hepatosplenomegaly. Foam cells in bone marrow, interstitial pneumonitis, a slight facial dysmorphy and normal psychomotor development were additional findings. Acid sphingomyelinase studies in lymphocytes (and later SMPD1 gene studies [c.151_154delGACT; c.1341-21_1341-18delAATG]) established the diagnosis of ASMD. Between the ages 6-27, he developed growth retardation, peripheral neuropathy, kyphoscoliosis, alopecia, and aortic valv
