ABSTRACT
OBJECTIVE@#To delineate the clinical and genetic features of a Chinese boy suspected for Niemann-Pick disease type C.@*METHODS@#The patient underwent clinical examination and was subjected to next generation sequencing. Suspected mutations were validated by Sanger sequencing. Potential impact of the novel mutation was predicted by SIFT, PolyPhen-2 and MutationTaster software.@*RESULTS@#The child has featured hepatosplenomegaly, increased direct bilirubin, jaundiced skin and liver damage. DNA sequencing showed that he has carried compound heterozygous mutations of NPC1 gene, namely c.2728GG (p.P90R), which were inherited from his mother and father, respectively. The c.2728G>A (p.G910S) mutation was previously reported, while the c.269C>G (p.P90R) was a novel mutation.@*CONCLUSION@#The child has suffered from Niemann-Pick disease type C due to mutations of NPC1 gene. Above finding has enriched the spectrum of NPC1 mutations and provided a basis for genetic counseling and prenatal diagnosis.
