Niemann-Pick Type C (NPC) – Market Outlook, Epidemiology, Competitive Landscape, and Market Forecast Report – 2023 To 2033

Niemann-Pick Type C (NPC) is a group of disorders that involve abnormalities of intracellular transport of endocytosed cholesterol within cells, resulting in the accumulation of unesterified cholesterol in lysosomes and late endosomes. This condition is inherited in an autosomal recessive manner and caused by mutations in the NPC1 or NPC2 genes. The functions of these proteins still need to be fully understood. NPC can be classified into three subtypes based on the age of onset of neurological manifestations: 1. Visceral-neurodegenerative form: Early-infantile (< 2 years) 2. Neurodegenerative form: Late-infantile (2–6 years), Juvenile (6–15 years) 3. Psychiatric-neurodegenerative form: Adult (> 15 years) Symptoms vary depending on the age of onset and may include jaundice, hepatosplenomegaly, ataxia, dysarthria, cognitive decline, seizures, dysphagia, and ca...
