Neonatal presentation of Niemann-Pick disease type C2- A rare case report.

Abstract

Niemann Pick type C [NP-C] disease is a rare neurodegenerative lysosomal storage disorder marked by an accumulation of unesterified cholesterol in the lysosomal system. It has autosomal recessive inheritance caused by mutations in NPC1 and NPC2 genes. The broad clinical spectrum ranges from a prenatal severe manifestation to an adult-onset chronic neurodegenerative disease. The manifestations in the perinatal period and infancy are predominantly visceral, with hepatosplenomegaly, jaundice, and pulmonary infiltrates (in some instances). Patients with NP-C usually do not show neurological manifestations during the neonatal period. Herein we present a case of neonatal cholestasis with hepatosplenomegaly and anaemia, which was diagnosed as Niemann Pick disease type C2. Thus, NP-C is an important differential diagnosis of neonatal cholestasis in the presence of visceromegaly.
