Summaries for Biotinidase Deficiency

NIH Rare Diseases : 54 Biotinidase deficiency is an inherited disorder in which the body is unable to recycle the vitamin biotin. The disorder may become apparent in the first few months of life, or later in childhood. The more severe form of the disorder is called 'profound biotinidase deficiency' and may cause delayed development, seizures, weak muscle tone (hypotonia), breathing problems, hearing and vision loss, problems with movement and balance (ataxia), skin rashes, hair loss (alopecia), and a fungal infection called candidiasis. The milder form is called 'partial biotinidase deficiency'; without treatment, affected children may experience hypotonia, skin rashes, and hair loss. In some cases, these symptoms only appear during illness, infection, or other times of stress on the body. Biotinidase deficiency is caused by mutations in the BTD gene and is inherited in an autosomal recessive manner. Lifelong treatment with biotin can prevent symptoms and complications from occurring or improve them if they have already developed.

MalaCards based summary : Biotinidase Deficiency, also known as late-onset multiple carboxylase deficiency, is related to holocarboxylase synthetase deficiency and multiple carboxylase deficiency, and has symptoms including seizures, ataxia and vomiting. An important gene associated with Biotinidase Deficiency is BTD (Biotinidase), and among its related pathways/superpathways are Biotin metabolism and Vitamin digestion and absorption. The drugs Miconazole and Immunologic Factors have been mentioned in the context of this disorder. Affiliated tissues include skin, cerebellum and spinal cord, and related phenotypes are muscular hypotonia and generalized myoclonic seizures

Disease Ontology : 12 A multiple carboxylase deficiency that involves a deficiency in biotinidase.

Genetics Home Reference : 26 Biotinidase deficiency is an inherited disorder in which the body is unable to recycle the vitamin biotin. If this condition is not recognized and treated, its signs and symptoms typically appear within the first few months of life, although it can also become apparent later in childhood.

OMIM : 58 Multiple carboxylase deficiency (MCD) is an autosomal recessive metabolic disorder characterized primarily by cutaneous and neurologic abnormalities. Symptoms result from the patient's inability to reutilize biotin, a necessary nutrient. Sweetman (1981) recognized that multiple carboxylase deficiency could be classified into early (see 253270) and late forms. The early form showed higher urinary excretion of 3-hydroxyisovaleric acid and 3-hydroxypropionic acid than the late form and was associated with normal plasma biotin concentrations. Sweetman (1981) proposed a defect in holocarboxylase synthetase and intestinal biotin absorption, respectively. Some patients with biotinidase deficiency present in infancy (Baumgartner et al., 1985; Kalayci et al., 1994), and some individuals with this deficiency are asymptomatic (Wolf et al., 1997). (253260)

UniProtKB/Swiss-Prot : 76 Biotinidase deficiency: A juvenile form of multiple carboxylase deficiency, an autosomal recessive disorder of biotin metabolism, characterized by ketoacidosis, hyperammonemia, excretion of abnormal organic acid metabolites, and dermatitis. Biotinidase deficiency is characterized by seizures, hypotonia, skin rash, alopecia, ataxia, hearing loss, and optic atrophy. If untreated, symptoms usually become progressively worse, and coma and death may occur.
