Unveiling the Role of APOB Variants in Familial Hypercholesterolemia: Functiona...
Ferreira, Maria Simões; Ramos, Diana; Rato, Inês; Jannes, Cinthia E.; Larrea-Sebal, Asier; Martín, César; Bourbon, Mafalda; Alves, Ana CatarinaFamilial hypercholesterolemia (FH) is a condition characterized by increased LDL cholesterol levels with APOB variants accounting for about 5-10% of FH cases. However, variants in this gene may be more common than initially estimated since the entire APOB gene has only recently started to be sequenced. Although most of the alterations are missense, nonsense variants and small indels in exon 29 were also identif...

Ferreira, Maria Simões; Chora, Joana Rita; Medeiros, Ana Margarida; Bourbon, Mafalda; Alves, Ana CatarinaFamilial hypercholesterolemia (FH) is clinically characterized by increased levels of circulating LDL cholesterol leading to premature coronary heart disease. It can be caused by variants in LDLR, APOB, and PCSK9 genes. APOB variants are responsible for 5-10% of the FH cases, p.(Arg3527Gln) being the most common. Only recently the whole gene has been sequenced due to Next Generation Sequencing, increasing the v...

Ferreira, Maria Simões; Alves, Ana Catarina; Larrea-Sebal, Asier; Martín, César; Bourbon, MafaldaFamilial hypercholesterolemia (FH) is an inherited lipid disorder characterized by increased levels of LDL cholesterol. About 5-10% of FH cases occur due to variants in the APOB gene, but these alterations can be a more common cause of FH than expected since most of APOB variants identified is still unknown their effect on the metabolism. The majority of the variants are missense but there are a few nonsense va...
ClinVar Analysis of APOB Variants Associated with Familial Hypercholesterolemia
Ferreira, Maria Simões; Alves, Ana Catarina; Bourbon, MafaldaFamilial hypercholesterolemia (FH) is an autosomal semi dominant disorder of lipid metabolism characterized by elevated LDL cholesterol levels associated with an increased cardiovascular risk. FH can be caused by variants in LDLR, APOB, and PCSK9 genes. Although most of the cases are due to variants in the LDLR gene, the APOB gene is responsible for 5-10% of the cases. The number of variants in this gene has be...
