[Niemann-Pick disease types A and B].
The molecular basis of Niemann-Pick disease, type A and B, has been confirmed by detection of mutations causing deficiency of the acid sphingomyelinase activity in the patients. It has been shown that mutations, which cause no activity of acid sphingomyelinase, are responsible for the type A and mutations which cause residual activities of the enzyme are responsible for the type B. Acid sphingo...
متن کاملAlleged Detrimental Mutations in the SMPD1 Gene in Patients with Niemann-Pick Disease
Loss-of-function mutations in the sphingomyelin phosphodiesterase 1 (SMPD1) gene are associated with decreased catalytic activity of acid sphingomyelinase (ASM) and are the cause of the autosomal recessive lysosomal storage disorder Niemann-Pick disease (NPD) types A and B. Currently, >100 missense mutations in SMPD1 are listed in the Human Gene Mutation Database. However, not every sequence va...
متن کاملIdentification of a distinct mutation spectrum in the SMPD1 gene of Chinese patients with acid sphingomyelinase-deficient Niemann-Pick disease
BACKGROUND Clinical observations and molecular analysis of the SMPD1 gene in Chinese patients with acid sphingomyelinase deficiency Niemann-Pick disease (NPD) are scarce. METHODS A cohort of 27 Chinese patients diagnosed with acid sphingomyelinase deficiency, within the past five years, were collected and investigated for genotype, phenotype, and their correlations. RESULTS The majority of ...
متن کاملCathepsin B overexpression in Niemann-Pick disease
Niemann Pick disease (NPD) is a lysosomal storage disease caused by the loss of acid sphingomyelinase (ASMase) that features neurodegeneration and liver disease. Since ASMase knockout mice models NPD and our previous findings revealed that ASMase activates cathepsins B/D (CtsB/D), our aim was to investigate the expression and processing of CtsB/D in hepatic stellate cells (HSC) from ASMase null...
