LIPIDOMICS OF HUMAN SKIN FIBROBLASTS IN NEIMANN-PICK DISEASE TYPE C

Neimann-Pick Disease type C is a hereditary lysosomal storage disease due to mutations of the NPC1 or NPC2 genes. The products of these genes encodes for components of a lysosomal machinery that transport different kinds of lipids across the lysosomal membrane. The main abnormalities of NPC1 de ciency phenotype is the accumulation of free cholesterol (FC) and sphingolipids (GL) in brain, liver and other organs cells. Neurodegeneration and hepato-splenomegaly are common ndings. The NPC disease, in his severe onset, leads to a precocious exitus, though the inhibition of glyco-SL synthesis by miglustat has shown some clinical bene t. Recently the physiopathological mechanism has been partly el…

A NOVEL APOB MUTATION IDENTIFIED BY EXOME SEQUENCING COSEGREGATES WITH STEATOSIS, LIVER CANCER AND HYPOCHOLESTEROLEMIA

Objective. In familial hypobetalipoproteinemia (FHBL), fatty liver is a characteristic feature, and there are several reports of associated cirrhosis and hepatocarcinoma. We investigated a large kindred in which low-density lipoprotein (LDL) cholesterol, fatty liver and hepatocarcinoma displayed an autosomal dominant pattern of inheritance. Approach and Results. The proband was a 25 year-old female with low plasma cholesterol and hepatic steatosis. Low plasma levels of total cholesterol and fatty liver were observed in 10 more family members; 1 member was affected by liver cirrhosis and four more subjects died of either hepatocarcinoma or carcinoma on cirrhosis. To identify the causal mutat…
