Wide spread variation in measurement results of total 25-hydroxyvitamin D (25(OH)D) confounds international efforts to develop evidence-based clinical guidelines. Accordingly, NIH Office of Dietary Supplements (ODS) in collaboration with CDC National Center for Environmental Health (NCEH), National Institute of Standards and Technology (NIST) and Ghent(More)
A defect in intracellular uptake of carnitine has been identified in patients with severe carnitine deficiency. To define the clinical manifestations of this disorder, the presenting features of 15 affected infants and children were examined. Progressive cardiomyopathy, with or without chronic muscle weakness, was the most common presentation (median age of(More)
New developments in the treatment and management of phenylketonuria (PKU) as well as advances in molecular testing have emerged since the National Institutes of Health 2000 PKU Consensus Statement was released. An NIH State-of-the-Science Conference was convened in 2012 to address new findings, particularly the use of the medication sapropterin to treat(More)
The National Institute of Standards and Technology (NIST), in collaboration with the National Institutes of Health's Office of Dietary Supplements (NIH-ODS), has developed a Standard Reference Material (SRM) for the determination of 25-hydroxyvitamin D [25(OH)D] in serum. SRM 972 Vitamin D in Human Serum consists of four serum pools with different levels of(More)
Genetic deficiency of short-chain acyl-coenzyme A (CoA) dehydrogenase activity was demonstrated in cultured fibroblasts from a 2-yr-old female whose early postnatal life was complicated by poor feeding, emesis, and failure to thrive. She demonstrated progressive skeletal muscle weakness and developmental delay. Her plasma total carnitine level (35 nmol/ml)(More)
Medium-chain acyl-CoA dehydrogenase (MCAD) deficiency is an inborn error of fatty-acid oxidation that is characterized by fasting intolerance and recurrent episodes of hypoglycemic coma which can be fatal. Its incidence is one of the highest among genetic metabolic disorders. Using a modified PCR and NcoI digestion method, we have surveyed 46 additional,(More)
The clinical and pathologic findings in 12 patients with medium-chain acyl CoA dehydrogenase deficiency and three patients with long-chain acyl CoA dehydrogenase deficiency are summarized. Although these inborn errors of intramitochondrial beta-oxidation of fatty acids present with similar findings to Reye's syndrome, there are clinical, laboratory and(More)
1. The esterase isozymes of human tissues have been investigated using the technique of starch-gel electrophoresis. Conventional naphthyl-azo dye linked stains and new fluorogenic staining methods were used to detect the isozymes. 2. Multiple isozymes were identified in every tissue and they were characterized in terms of their electrophoretic mobility,(More)
The genomic sequences encoding the human lysosomal acid lipase/cholesteryl esterase (sterol esterase; EC 3.1.1.13) have been isolated and sequenced, and the information has been used to identify mutations in both alleles of the gene from a patient with Wolman disease, an autosomal recessive lysosomal lipid storage disorder. The genomic locus consists of 10(More)
A roundtable to discuss the measurement of vitamin B-12 (cobalamin) status biomarkers in NHANES took place in July 2010. NHANES stopped measuring vitamin B-12-related biomarkers after 2006. The roundtable reviewed 3 biomarkers of vitamin B-12 status used in past NHANES--serum vitamin B-12, methylmalonic acid (MMA), and total homocysteine (tHcy)--and(More)
