Abstract

Background: Niemann-Pick disease type C (NPC) is a rare, fatal neurovisceral disorder with autosomal recessive inheritance, and featuring striking clinical variability dependent on the age at onset of neurological symptoms. We report data from a large cohort of 56 Czech patients with NPC diagnosed over a period of 37 years.

Methods: An observational, retrospective analysis of historic and current clinical and laboratory information was performed among all NPC patients originating from the area of the contemporary Czech Republic and diagnosed between 1975 and 2012. The data obtained demonstrate the evolution of the diagnostic process in NPC over the last four decades.

We estimate the contemporary birth prevalence of NPC in the Czech Republic at 0.93 per 100,000.
