Classical galactosemia is caused by one common missense mutation (Q188R) and by several rare mutations in the galactose-1-phosphate uridyltransferase (GALT) gene. The most common variant of GALT, the Duarte variant, occurs as two types, Duarte-1 (D-1) and Duarte-2 (D-2), both of which carry the sequence change N314D. D-1 increases, whereas D-2 decreases(More)
Apolipoprotein (apo) A-IV, a structural component of chylomicrons and high-density lipoproteins, may play a role in the catabolism of triglyceride-rich lipoproteins and in reverse cholesterol transport. To study the regulation of apoA-IV gene expression by genetic and nutritional factors, we determined the effect of a fish oil-rich and a sucrose-rich diet(More)
Newborn screening for galactosemia yields a high number of false-positive results. Confirmatory DNA testing for unknown galactosemia mutations on the initial positive sample using novel techniques of mutation detection tenders itself to reduce the recall rate. The potential benefits of confirmatory DNA testing, however, could be offset by the detection of a(More)
BACKGROUND: Obesity is associated with disorders of plasma lipid transport in many, but not in all obese subjects. The effects of obesity on the regulation of genes involved in plasma lipid transport may depend on specific mutations causing or contributing to obesity and/or on interactions of a specific obesity mutation with the genetic background. The(More)
Primary infection with Toxoplasma gondii during pregnancy may affect the fetus and result in congenital toxoplasmosis. In Austria serological screening for detection of newly acquired infection during pregnancy was introduced in 1975. In this study we used polymerase chain reaction (PCR) for detection of fetal infection with Toxoplasma gondii. Amniotic(More)
In Austria, neonatal screening for congenital hypothyreosis has been introduced since 1976 as a part of the national screening program for inborn errors of metabolism. Capillary blood spots are collected on filter paper from all newborns on day 3 to 5 and are subsequently investigated with a delayed fluorescence-immunoassay (DELFIA) for the determination of(More)
Plasma high density lipoprotein (HDL) is inversely associated with the development of atherosclerosis. HDL exerts its atheroprotective role through involvement in reverse cholesterol transport in which HDL is loaded with cholesterol at the periphery and transports its lipid load back to the liver for disposal. In this pathway, HDL is not completely(More)
Lipid and lipoproteins were examined in 7 males patients with coronary heart disease, 10 males with coronary heart and peripheral vascular disease, 25 males with peripheral vascular disease and 10 females with peripheral vascular disease aged between 50-60 years. In general our results demonstrate that in all patients with different locations of(More)
Newborn screening for biotinidase deficiency (BD) provides prevention of neurological sequelae in patients with low residual enzyme activity by early treatment with oral biotin substitution. Screening 1.1 million newborns in Austria and consecutive family studies led to the identifcation of 21 patients with profound BD (residual activity <10%) (incidence:(More)
The high density lipoprotein (HDL) receptor, scavenger receptor class B, type I (SR-BI), mediates selective cholesteryl ester uptake from lipoproteins into liver and steroidogenic tissues but also cholesterol efflux from macrophages to HDL. Recently, we demonstrated the uptake of HDL particles in SR-BI overexpressing Chinese hamster ovarian cells(More)
