The type of LDLR gene mutation predicts cardiovascular risk in children with familial hypercholesterolemia.

Objective: To ascertain whether the molecular characterization of a defect in the low-density lipoprotein (LDL) receptor gene (LDLR) in children with heterozygous familial hypercholesterolemia (heFH) identifies subjects at greater risk of developing premature coronary artery disease (pCAD) later in life.

Study Design: We investigated 264 children with heFH from 201 families, along with 148 affected parents and 100 unaffected siblings. The lipid profile was assessed before any treatment was provided, and genotype analysis was performed to characterize LDLR defects.

Cholesteryl Ester Storage Disease (CESD) due to novel mutations in the LIPA gene.

Cholesteryl Ester Storage Disease (CESD) is a rare recessive disorder due to mutations in LIPA gene encoding the lysosomal acidic lipase (LAL). CESD patients have liver disease associated with mixed hyperlipidemia and low plasma levels of high-density lipoproteins (HDL). The aim of this study was the molecular characterization of three patients with CESD.

Quantitative polymerase chain reaction and microchip electrophoresis to detect major rearrangements of the low-density lipoprotein receptor gene causing familial hypercholesterolemia.

A variety of rearrangements in the low-density lipoprotein receptor (LDLR) gene cause severe forms of familial hypercholesterolemia (FH). However, current methods for searching these abnormalities in FH samples, e.g.
