Niemann-Pick disease Type C – causes, symptoms, diagnosis, treatment, pathology

Niemann-Pick disease type C, or NPC, is a rare genetically inherited condition caused by mutations in either the NPC1 or NPC2 genes. These mutations impair intracellular transport of cholesterol and other molecules, which causes progressive neurologic and developmental problems. Now, cholesterol reaches the cells packed in lipoproteins, which bind to low density lipoprotein, or LDL,…

Gaucher disease is an inherited condition characterized by insufficient levels of the enzyme glucocerebrosidase, also called beta-glucosidase. It’s named for the French physician, Philippe Gaucher, who first described the condition. Glucocerebroside is a glycolipid, which is a molecule containing both sugar and fat, that’s included in the membrane of many different cells. Glucocerebroside is formed…
