    Timely diagnosis of sitosterolemia by next generation sequencing in two children with severe hypercholesterolemia.
    Atherosclerosis 2017 Jul 4;262:71-77. Epub 2017 May 4.
    Department of Biomedical, Metabolic and Neural Sciences, University of Modena and Reggio Emilia, Modena, Italy. Electronic address:
    Background And Aims: Severe hypercholesterolemia associated or not with xanthomas in a child may suggest the diagnosis of homozygous autosomal dominant hypercholesterolemia (ADH), autosomal recessive hypercholesterolemia (ARH) or sitosterolemia, depending on the transmission of hypercholesterolemia in the patient's family. Sitosterolemia is a recessive disorder characterized by high plasma levels of cholesterol and plant sterols due to mutations in the ABCG5 or the ABCG8 gene, leading to a loss of function of the ATP-binding cassette (ABC) heterodimer transporter G5-G8.

    Methods: We aimed to perform the molecular characterization of two children with severe primary hypercholesterolemia. Read More

    Internist (Berl) 2017 May 17. Epub 2017 May 17.
    Charité, Universitätsklinik Berlin, Augustenburger Platz 1, 13353, Berlin, Deutschland.
    Severe hypertriglyceridemia is defined at a plasma triglyceride (TG) concentration of >885 mg/dl and may result - in particular when clinical symptoms appear before the age of 40 - from "large variant" mutations in genes which influence the function of the lipoprotein lipase (LPL). For diagnosis, secondary factors have to be excluded and treated before further genetic tests are considered. Typical symptoms in almost all patients are recurrent, sometimes severe abdominal pain attacks, which can result in acute pancreatitis, the most important, sometimes life-threatening complication.

    [Hyperlipoproteinemia and dyslipidemia as rare diseases. Diagnostics and treatment].
    Vnitr Lek Fall 2016;62(11):887-894
    Hyperlipoproteinemia (HLP) and dyslipidemia (DLP) are of course mainly perceived as diseases of common incidence and are typically seen as the greatest risk factors (RF) in the context of the pandemic of cardiovascular diseases. This is certainly true and HLP or DLP overall affect tens of percents of adults. However we cannot overlook the fact that disorders (mostly congenital) of lipid metabolism exist which, though not formally defined as such, amply satisfy the conditions for classification as rare diseases.
