Abstract:
Objective To discuss the clinical features,hepatic pathology,and prognosis of cerebrotendinous xanthomatosis in a child caused by CYP27A1 mutation.Methods Clinical features of a child with cerebrotendinous xanthomatosis were retrospectively analyzed,and the related literatures viewed.Results The child had different degrees of cholestasis,hepatomegaly,elevated transaminases,normal-glutamyl GGT(γ-GT) and normal total bile acid.The hepatic pathology showed intrahepatic cholestasis,inflammatory cell infiltration and expansion and hyperplasia of bile capillary.Gene testing found heterozygous mutations of CYP27A 1 (c.1263+ l G>A/c.1477-3C>G) in the child.The variant of c.1477-3C>G is a novel mutation.Conclusions The possibility of bile acid synthesis disorder should be considered when infants have cholestasis,elevated transaminase,hepatomegaly,and normal or reduced γ-GT and total bile acid.Gene testing should be used for early diagnosis,treatment to improve prognosis.
