Newborn screening for biotinidase deficiency in Brazil: biochemical and molecular characterizations. (1/10)

Biotinidase deficiency is an inherited metabolic disorder characterized by neurological and cutaneous symptoms. Fortunately, it can be treated and the symptoms prevented by oral administration of the vitamin biotin. Using dried blood-soaked filter paper cards, biotinidase activity was determined in the sera of 225,136 newborns in Brazil. Mutation analysis performed on DNA from 21 babies with low serum biotinidase activity confirmed that 3 had profound biotinidase deficiency (less than 10% of mean normal sera biotinidase activity), 10 had partial biotinidase deficiency (10 to 30% of mean normal serum activity), 1 was homozygous for partial biotinidase deficiency, 4 were heterozygous for either profound or partial deficiency, and 3 were normal. Variability in serum enzyme activities and discrepancies with mutation analyses were probably due to inappropriate handling and storage of samples sent to the laboratory. Obtaining an appropriate control serum at the same time as that of the suspected child will undoubtedly decrease the false-positive rate (0.09%). Mutation analysis can be used to confirm the genotype of these children. The estimated incidence of biotinidase deficiency in Brazil is about 1 in 9,000, higher than in most other countries. Screening and treatment of biotinidase deficiency are effective and warranted. These results strongly suggest that biotinidase deficiency should be included in the newborn mass screening program of Brazil.  (+info)

Evaluation of the probabilistic distribution of dietary biotin intake in Japan using Monte Carlo simulation. (6/10)

Biotin is a widely distributed water soluble vitamin. Adequate intake of biotin was set at 50 microg/d in Japan 2010. Recently, the importance of the application of probabilistic techniques to estimate the share of the population at risk of deficient and excessive nutrient intake has been increasingly emphasized for assessing nutrient adequacy. Monte Carlo simulation, a computer-based method of analysis that uses statistical sampling techniques yielding a probabilistic approximation to the solution of a mathematical model, has been used to estimate the probabilistic distribution of the dietary intake of food chemicals. For this study, we used two preliminary models to estimate the dietary biotin intake with food consumption data based on the National Health and Nutrition Survey in Japan. One is evaluated by biotin concentration data from the total diet study; the other is a dataset of biotin concentration in individual foods. After removing outliers from the individual foods dataset, probability density distributions from two models showed analogous mean, median, 5th percentile, and 95th percentile values. The daily biotin intakes from these probabilistic methods showed that more than 80% of the Japanese population had higher than the adequate intake of biotin. However, the contribution of each food group to the total daily biotin intake was somewhat different. Improvement of these methods necessitates the collection of more actual data associated with sample compositional variability and evaluation of uncertainty associated with the food group classification of biotin.  (+info)

Biotinidase deficiency is an autosomal recessive metabolic disorder in which biotin is not released from proteins in the diet during digestion or from normal protein turnover in the cell. This situation results in biotin deficiency. Biotin, also called vitamin B7, is an important water-soluble nutrient that aids in the metabolism of fats, carbohydrates, and proteins. Biotin deficiency can result in behavioral disorders, lack of coordination, learning disabilities and seizures. Biotin supplementation can alleviate and sometimes totally stop such symptoms. Signs and symptoms of a biotinidase deficiency can appear several days after birth. These include seizures, hypotonia and muscle/limb weakness, ataxia, paresis, hearing loss, optic atrophy, skin rashes (including seborrheic dermatitis and psoriasis), and alopecia. If left untreated, the disorder can rapidly lead to coma and death. Biotinidase deficiency can also appear later in life. This is referred to as late-onset biotinidase deficiency. ...

Phenylketonuria (PKU) is caused by a defect in the conversion of the amino acid phenylalanine (Phe) to tyrosine (Tyr). Without treatment, patients develop mental retardation. Inclusion of the Phe/Tyr ratio has decreased the number of false positive screening outcomes to the present PPV of 0.92 without any known missed cases. The recall levels have been lowered several times since the start of screening. An increase in the incidence of patients with milder disease has been observed with time. We were able to show that the impact of the adjusted recall levels was low. Instead, milder genetic variants, which are more common in Southern Europe, are found more often, which is an effect of the large number of non-Nordic immigrants who have come to Sweden during the last 25 years. The immigration has widened the spectrum of detected pathogenic variants ...

Biotinidase deficiency is a rare inherited metabolic disorder that can cause severe neurological symptoms. To prevent severe clinical presentations, it was included in the Dutch neonatal screening programme in 2007. Since then the number of cases detected has been high. This study set out to describe the incidence of the disease, the clinical and demographic characteristics of the neonates identified and the type of mutations found. In the south-western Netherlands, 304 982 neonates were screened between 2007 and 2012; and 92 were identified for further testing. Confirmatory testing revealed 6 (7%) with a profound biotinidase deficiency (|10% enzyme activity), 44 (48%) with a partial deficiency (10-30%) and 42 (46%) with normal activity (|30%). All six patients whose profound deficiency was confirmed had enzyme activities below 15% on neonatal screening. Mutation analysis was performed in 61 neonates: 5 profound, 35 partial and 21 normal. All five profound cases had two severe mutations.
Biotinidase (BTD), a ubiquitous mammalian cell enzyme, is present in high levels in the serum, liver, and kidneys. Its primary enzymatic function is to cleave the vitamin biotin (also known as coenzyme R, vitamin H, or vitamin B7) from the organic compound biocytin.

In accordance with section 1 of REACH Annex XI (testing does not appear scientifically necessary), the long-term or reproductive toxicity to birds study (required in section 9.6.1.) does not need to be conducted as the substance is not classified as hazardous for environmental effects and the chemical safety assessment concludes that the substance is of no immediate concern to the environment. The available data are adequate for classification and labelling purposes and PBT assessment is not required for inorganic substances so no further testing is required. Furthermore, any ionic metal leaching out of the substance in environmental conditions is predicted to bind strongly to soil and sediments. On this basis the bioavailable concentration of manganese from the substances to terrestrial organisms and ultimately to birds is predicted to be much less than the background concentration of manganese in European soils (428.6 mg Mn/kg according to Probabilistic Distribution of Manganese in European ...

TY - JOUR. T1 - Epigenetic regulation of chromatin structure and gene function by biotin. AU - Hassan, Yousef I.. AU - Zempleni, Janos. PY - 2006/7/6. Y1 - 2006/7/6. N2 - Covalent modifications of histones are a crucial component of epigenetic events that regulate chromatin structures and gene function. Evidence exists that distinct lysine residues in histones are modified by covalent attachment of the vitamin biotin, catalyzed by biotinidase and holocarboxylase synthetase. Biotinylation of histones appears to be conserved across species. The following biotinylation sites were identified using both MS and enzymatic biotinylation of synthetic peptides: K9, K13, K125, K127, and K129 in histone H2A; K4, K9, and K18 in histone H3; and K8 and K12 in histone H4. Evidence was provided that biotinylated histone H4 is enriched in pericentromeric heterochromatin, and that biotinylation of histone H4 participates in gene silencing, mitotic condensation of chromatin, and the cellular response to DNA damage. ...
A simple and rapid UPLC-MS/MS method to simultaneously determine gemcitabine and its L-carnitine ester derivative(2-deoxy-2, 2-difluoro-N-((4-amino-4-oxobutanoyl) oxy)-4-(trimethyl amm-onio) butanoate-cytidine, JDR) in rat plasma was developed and validated.The conventional plasma sample preparation method of nucleoside analogues is solidphase extraction(SPE) which is time-consuming and cost-expensive. In this study, gradient elution with small particles size solid phase was applied to effectively separate gemcitabine and JDR, and protein precipitation pretreatment was adopted to remove plasma protein and extract the analytes with high recovery(81%). Method validation was performed as per the FDA guidelines, and the standard curves were found to be linear in the range of 5-4000 ng/ml for JDR and 4-4000 ng/ml for gemcitabine, respectively. The lower limit of quantitation(LLOQ)of gemcitabine and JDR was 4 and 5 ng/ml, respectively. The intra-day and inter-day precision and accuracy results were within

In therapeutic riding, we often see clients who have issues with muscle tone. Hypertonia and hypotonia are two terms used to describe muscle tone. Hypertonia means high muscle tone and lack of flexibility. This often involves stiff movements and poor balance. Hypotonia means low muscle tone and too much flexibility, which can result in difficulty…

TY - JOUR. T1 - Clustering of mutations in the biotin-binding region of holocarboxylase synthetase in biotin-responsive multiple carboxylase deficiency. AU - Dupuis, Lucie. AU - Leon-Del-Rio, Alfonso. AU - Leclerc, Daniel. AU - Campeau, Eric. AU - Sweetman, Lawrence. AU - Saudubray, Jean Marie. AU - Herman, Gail. AU - Gibson, K. Michael. AU - Gravel, Roy A.. PY - 1996/7. Y1 - 1996/7. N2 - Holocarboxylase synthetase (HCS) catalyses the biotinylation of the four biotin-dependent carboxylases found in humans. A deficiency in HCS results in biotin-responsive multiple carboxylase deficiency (MCD). We have identified six different point mutations in the HCS gene in nine patients with MCD. Two of the mutations are frequent among the MCD patients analyzed. Four of the mutations cluster in the putative biotin-binding domain as deduced from the corresponding Escherichia coli enzyme and consistent with an explanation for biotin-responsiveness based on altered affinity for biotin. The two others may define ...
Multiple carboxylase deficiency is characterized by deficient activities of three biotin-dependent enzymes, propionyl coenzyme A carboxylase, pyruvate carboxylase, and β-methylcrotonyl coenzyme A carboxylase. A newborn infant was seen with metabolic ketoacidosis, hyperammonemia, organic aciduria, seizures, and coma. Multiple carboxylase deficiency was subsequently confirmed by enzyme activity determinations in his peripheral blood beukocytes and cultured skin fibroblasts. The infants neurologic and metabolic status improved markedly within a few days of administration of pharmacologic doses of oral biotin. His EEG, which was distinctly abnormal, became normal; his extensive computed tomography scan changes resolved, with the exception of ventricular dilation, over the next two months. After two weeks of biotin treatment the excretion of abnormal organic acid metabolites was reduced and his carboxylase activities increased to the normal range. However, the activities of these enzymes increased ...

3-methylglutaconic aciduria 1. An inborn error of leucine metabolism. It leads to an autosomal recessive syndrome with variable clinical phenotype, ranging from delayed speech development to severe psychomotor retardation, coma, failure to thrive, metabolic acidosis and dystonia. MGA1 can be distinguished from other forms of MGA by the pattern of metabolite excretion: 3-methylglutaconic acid levels are higher than those detected in other forms, whereas methylglutaric acid levels are usually only slightly elevated and there is a high level of 3-hydroxyisovaleric acid excretion (not present in other MGA forms)..
