Summaries for Niemann-Pick Disease, Type a

About this section
OMIM : 58 Niemann-Pick disease types A and B are caused by an inherited deficiency of acid sphingomyelinase activity. The clinical phenotype ranges from a severe infantile form with neurologic degeneration resulting in death usually by 3 years of age (type A) to a later-onset nonneurologic form (type B) that is compatible with survival into adulthood. Since intermediate cases also have been reported, the disease is best regarded a single entity with a clinical spectrum (summary by Schuchman, 2007). Knudson and Kaplan (1962) suggested that 3 types of the disorder can be distinguished: infantile cerebral, juvenile cerebral, and noncerebral. Later, 5 forms of Niemann-Pick disease were distinguished. Four were delineated by Crocker (1961): the classical infantile form (type A), the visceral form (type B), the subacute or juvenile form (type C; 257220), and the Nova Scotian variant (type D; see 257220). The fifth, the adult form (type E; see 607616), was described by Terry et al. (1954) and Lynn and Terry (1964). Schneider et al. (1978) used the designation type F (see 607616) for a form characterized in 2 patients by a thermolabile enzyme. Most patients fall into Crocker's group A, with death before age 3 years. Schuchman (2007) provided a detailed review of Niemann-Pick disease type A, including clinical management. (257200)

MalaCards based summary : Niemann-Pick Disease, Type a, also known as niemann-pick disease type a, is related to niemann-pick disease, type b and acid sphingomyelinase deficiency, and has symptoms including muscle weakness, constipation and vomiting. An important gene associated with Niemann-Pick Disease, Type a is SMPD1 (Sphingomyelin Phosphodiesterase 1), and among its related pathways/superpathways are Metabolism and Statin Pathway. The drugs Miglustat and 1-Deoxynojirimycin have been mentioned in the context of this disorder. Affiliated tissues include brain, bone and bone marrow, and related phenotypes are cherry red spot of the macula and intellectual disability

Disease Ontology : 12 A Niemann-Pick disease characterized by onset in infancy and involvement of neurological tissues that has material basis in an autosomal recessive mutation of SMPD1 on chromosome 11p15.4.

NIH Rare Diseases : 54 Niemann-Pick disease is an inherited condition involving lipid metabolism, which is the breakdown, transport, and use of fats and cholesterol in the body. In people with this condition, abnormal lipid metabolism causes harmful amounts of lipids to accumulate in the spleen, liver, lungs, bone marrow, and brain. Niemann-Pick disease type A appears during infancy and is characterized by an enlarged liver and spleen (hepatosplenomegaly), failure to gain weight and grow at the expected rate (failure to thrive), and progressive deterioration of the nervous system. Due to the involvement of the nervous system, Niemann-Pick disease type A is also known as the neurological type. There is currently no effective treatment for this condition and those who are affected generally do not survive past early childhood. Niemann-Pick disease type A is caused by mutations in the SMPD1 gene. It is inherited in an autosomal recessive pattern. 

UniProtKB/Swiss-Prot : 76 Niemann-Pick disease A: An early-onset lysosomal storage disorder caused by failure to hydrolyze sphingomyelin to ceramide. It results in the accumulation of sphingomyelin and other metabolically related lipids in reticuloendothelial and other cell types throughout the body, leading to cell death. Niemann-Pick disease type A is a primarily neurodegenerative disorder characterized by onset within the first year of life, mental retardation, digestive disorders, failure to thrive, major hepatosplenomegaly, and severe neurologic symptoms. The severe neurological disorders and pulmonary infections lead to an early death, often around the age of four. Clinical features are variable. A phenotypic continuum exists between type A (basic neurovisceral) and type B (purely visceral) forms of Niemann-Pick disease, and the intermediate types encompass a cluster of variants combining clinical features of both types A and B.
