Overview

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.[1][2] 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).[1][2][3] Niemann-Pick disease type B is caused by changes (mutations or variants) in the SMPD1 gene. It is inherited in an autosomal recessive fashion.[1] 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.[2][3]
