Incidence - The incidence of profound biotinidase deficiency is approximately 1 in 137,000 births. The prevalence of partial biotinidase deficiency is approximately 1 in 110,000 people. Since partial biotinidase deficiency can be mild, it is possible that the true prevalence is more common.. The condition is most common among individuals of European descent. However, it is also reported among individuals of Turkish, Saudi Arabian, and Japanese descent.. The early-onset form usually begins during the newborn (neonatal) period. The juvenile form usually begins at about three months of age. Males and females are affected in equal numbers.. Inheritance This condition is inherited in an autosomal recessive pattern. The parents of an individual with biotinidase deficiency each carry one copy of the mutated gene, but they typically do not have any health problems associated with the condition.. Cause - Mutations in the BTD gene cause biotinidase deficiency. The BTD gene provides instructions for making ...

Thirty-three positive cases of BTD were identified out of 264 727 infants screened by the Wolf colorimetric system during the period of this study by MN NBS. Five cases of profound BTD (0.1 to ,0.6 nmol/min per ml) and 26 cases of partial BTD (0.9 to 2.3 nmol/min per ml) were later confirmed through measurement of serum biotinidase activity. The incidence of combined partial and profound BTD of 1/8540 and that of profound BTD of ...

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.

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. ...

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. ...

N2 - Biotinidase deficiency is an autosomal recessively inherited disorder characterized by neurological and cutaneous abnormalities. Untreated individuals with biotinidase deficiency cannot recycle biotin from biocytin (N-biotinyl-ϵ-lysine), the proteolytic digestion product of protein-bound biotin. Biotin therapy can markedly resolve symptoms, or can prevent the development of symptoms if initiated early. To understand better the ...

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 ...

Symptoms of untreated biotinidase deficiency may appear at any time from 1 week to 10 years of age. The most common early symptoms include seizure activity of various types (myoclonic, grand mal, and focal or infantile spasms) and hypotonia. Other early symptoms include breathing problems (tachypnoea, hyperventilation, stridor and apnoea), skin rashes and alopecia. Later developmental delay, speech problems, ataxia, and vision and hearing problems may occur. Less frequent findings include feeding difficulties, vomiting/diarrhoea, fungal infections, hepatomegaly and splenomegaly. ...

A possible genetic basis should be considered in children with metabolic acidosis not attributable to another disorder, especially if the acidosis cannot be explained by elevated lactate and/or ß-hydroxybutyrate.. Blood gas arterial or venous.. Organic acids urine (collected during acidotic episode); a normal result, when not acutely ill, does not exclude these disorders. In some diseases (eg, biotinidase deficiency) metabolic acidosis may not occur, but the abnormal organic acids can be detected in the urine.. Identification of the specific disorder depends on the pattern of organic acids excreted during attacks.. Ammonia and Glucose should be measured, as many organic acidaemias are associated with hyperammonaemia and/or hypoglycaemia.. See also Hyperammonaemia, Hypoglycaemia. Naming of specific disorders is usually based on the acid(s) excreted or the deficient enzyme(s).. ...

U.S., Feb. 27 -- ClinicalTrials.gov registry received information related to the study (NCT03034707) titled Interference of Biotin Supplementation in Biotin-streptavidin Platforms for Hormone Testing on Jan. 17. Brief Summary: The B vitamin biotin is widely available as an over the counter supplement, often advertised and used to promote health of hair, skin and nails. Commercially available over the counter biotin supplements contain dose ranges up to 10 mg/day (ie 333 times higher than the recommended dietary allowance). The biotin molecule is also sometimes used as part of the lab technology to measure hormone and protein levels in the blood. It is possible that high doses of ingested biotin may interfere with accurate hormone or protein measurement using biotin related in vitro measurement systems. Such interference, if present, could lead to misdiagnosis. The study will analyze laboratory levels obtained with streptavidin-biotin assay systems while ingesting biotin in currently available ...

Fluorescent Dyes , Biotins and Streptavidins , Streptavidin, recombinant; Streptavidin is a nonglycosylated, tetrameric protein, with each subunit able to bind a single molecule of the vitamin biotin. Streptavidin-biotin bond is the strongest known non-covalent interaction with Kd ~10-15 M. Because streptavidin lacks any carbohydrate modification and has a near-neutral pI, it has the advantage of much lower nonspecific binding than avidin. Streptavidin is broadly used in various applications such as immunoassays, histochemistry, FISH (Fluorescence In Situ Hybridization), flow cytometry, microarrays and blot analysis.
