Functional characterization of 2 news variants in the APOB gene

Familial hypercholesterolaemia (FH) is an autosomal dominant disorder of cholesterol metabolism. Loss of function mutations in LDLR and APOB and also gain of function mutations in PCSK9 have been associated with FH, but mutations in LDLR are the most common cause of FH. Until 2012 only mutations in two small fragments of exon 26 and 29 were described as causing FH. However with Next Generation Sequencing techni...

Functionally characterization of the most common LDLR missense alterations foun...

Mutations in the LDLR gene are the major cause of familial hypercholesterolaemia (FH), which results in defective catabolism of LDL leading to premature coronary heart disease. Presently, more than 1700 different mutations in the LDLR gene have been described as causing FH but the majority of them remain without functional characterization. In the Portuguese Familial Hypercholesterolemia Study (PFHS), 123 LDLR ...

Genetic Diagnosis of Familial Hypercholesterolaemia: The Importance of an Integ...

Familial Hypercholesterolaemia (FH) is one of the most common monogenic disorders, being caused mostly by mutations in LDL receptor (LDLR) gene. The high levels of LDL cholesterol presented since birth confers these patients an increased cardiovascular risk. Laboratory techniques have improved greatly recently and new variants are found every day that need to be validated as mutations causing disease for the co...

Familial hypercholesterolaemia (FH) is an inherited autosomal dominant disorder resulting from defects in the low-density lipoprotein receptor (LDLR), in the apolipoprotein B (APOB) or in the proprotein convertase subtilisin/kexin type 9 (PCSK9) genes. In the majority of the cases FH is caused by mutations occurring within LDLR, while only few mutations in APOB and PCSK9 have been proved to cause disease. p.(Ar...

The importance of an integrated analysis of clinical, molecular, and functional...

Purpose: Familial hypercholesterolemia (FH) is one of the most common monogenic disorders, and the high concentrations of low-density lipoprotein (LDL) cholesterol presented since birth confers on these patients an increased cardiovascular risk. More than 1,600 alterations have been described in the LDL receptor gene (LDLR), but a large number need to be validated as mutations causing disease to establish a dia...

Advantages and Versatility of Fluorescence-Based Methodology to Characterize th...

Familial hypercholesterolemia (FH) is a common autosomal codominant disease with a frequency of 1∶500 individuals in its heterozygous form. The genetic basis of FH is most commonly mutations within the LDLR gene. Assessing the pathogenicity of LDLR variants is particularly important to give a patient a definitive diagnosis of FH. Current studies of LDLR activity ex vivo are based on the analysis of 125I-labeled...
