Niemann-Pick type C (NP-C) is a rare, autosomal recessive disorder. At least 95% of all the cases with this disease are due to mutations in the NPC1 gene. The clinical signs and symptoms of NP-C are classified into visceral, neurological and psychiatric. Our aim is to report the clinical findings, molecular results and filipin staining of 4 patients. The age of onset, expressed as median and range, was 0.2 (0.08-4.0) years and the age of diagnosis was 4.0 (2.5-8.9) years. Neurological and/or visceral manifestations were presented in our patients. Foamy cells in bone marrow biopsy were found in two patients. Through a molecular analysis of NPC1 gene, one non-reported (novel) and 4 previously described mutations were found. The filipin staining showed a positive pattern in all the patients. The diagnostic confirmation of these pediatric patients means a contribution to the casuistry of this disease in Argentina. |
