Background and objetive: To describe a new molecular variant of Niemann-Pick disease type C (NPC) in a 27 year-old patient with splenomegaly and abolition of osteotendinous reflexes.
Material and methods: NPC1 is the main gene with described mutation in NPC disease. Here we report a case with a new mutation, p.N916S, not described before in a patient diagnosed with NPC.
Results: p.N916S was described as a cause of NPC disease by predictive programmes Mutation Master, PolyPhen2 and SIFT.
Conclusions: p.N916S is a new mutation detected as a cause of NPC disease in a patient without severe neurological symptoms.
