Summaries for Niemann-Pick Disease, Type B

NIH Rare Diseases : 54 Niemann-Pick disease type B is an inherited condition involving lipid metabolism. People with this condition experience a build up of lipids in the spleen, liver, lungs, bone marrow, and brain. Signs and symptoms typically develop in the pre-teen years and may include enlarged liver and spleen (hepatosplenomegaly), short stature, problems with lung function including frequent lung infections, and a low number of platelets in the blood (thrombocytopenia). Niemann-Pick disease type B is caused by changes (mutations or variants) in the SMPD1 gene. It is inherited in an autosomal recessive fashion. Treatment is aimed at addressing the symptoms present in each individual. Bone marrow transplantation has been attempted in a few individuals. Researchers are working to develop additional options for treatment, including enzyme replacement and gene therapy.

MalaCards based summary : Niemann-Pick Disease, Type B, also known as niemann-pick disease type b, is related to niemann-pick disease, type a and niemann-pick disease, type c1, and has symptoms including muscle weakness, constipation and vomiting. An important gene associated with Niemann-Pick Disease, Type B is SMPD1 (Sphingomyelin Phosphodiesterase 1), and among its related pathways/superpathways are Lipoprotein metabolism and Ca, cAMP and Lipid Signaling. The drugs alemtuzumab and Busulfan have been mentioned in the context of this disorder. Affiliated tissues include bone, bone marrow and brain, and related phenotypes are splenomegaly and recurrent respiratory infections

Disease Ontology : 12 A Niemann-Pick disease characterized by visceral involvement only and survival into adulthood that has material basis in an autosomal recessive mutation of SMPD1 on chromosome 11p15.4.

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). Schuchman (2007) provided a detailed review of Niemann-Pick disease type B, including clinical management. (607616)

UniProtKB/Swiss-Prot : 76 Niemann-Pick disease B: A late-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. Clinical signs involve only visceral organs. The most constant sign is hepatosplenomegaly which can be associated with pulmonary symptoms. Patients remain free of neurologic manifestations. However, 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. In Niemann-Pick disease type B, onset of the first symptoms occurs in early childhood and patients can survive into adulthood.
