Niemann-Pick Disease Type C (NPC) 

Niemann-Pick disease Type C (NPC) is a rare genetic disorder, occurring in approximately 1 in 100,000 live births. It is an autosomal recessive, lysosomal storage disorder caused by mutations in either the NPC1 or NPC2 genes. These mutations lead to lysosomal and mitochondrial dysfunction, resulting in progressive neurodegeneration.

Clinical Symptoms

NPC is a heterogenous disease characterized by neurological, systemic, and psychiatric manifestations, resulting in significant functional and cognitive impairment.

The entire central nervous system is typically affected in NPC. Neuronal dysfunction and death causes damage throughout the brain, resulting in a variety of serious and debilitating physical and cognitive symptoms often resulting in premature death. 

Disease Presentation 

The course of NPC varies highly from patient to patient depending on the age of onset of neurological symptoms, from a rapidly progressing neonatal form to an adult-onset chronic neurodegenerative condition. Individuals whose neurological symptoms begin in early childhood generally have a faster disease progression than individuals whose symptoms begin later in life. The impact of NPC on affected individuals and their caregivers is often profound regardless of disease severity.

NPC is a serious, debilitating, progressive, neurodegenerative condition.

There are currently no FDA approved therapies to treat NPC. Management strategies focus on symptomatic relief and improving quality of life. This includes the use of medications to control neurological symptoms, physical therapy, and supportive care.

NPC Support & Resources

The International Niemann Pick Disease Alliance (INPDA) is a global network of non-profit organizations, supporting persons affected by Niemann Pick diseases (NPD). Currently, there are member organizations from 19 countries.
