Summaries for BTD Gene

Entrez Gene Summary for BTD Gene

  • The protein encoded by this gene functions to recycle protein-bound biotin by cleaving biocytin (biotin-epsilon-lysine), a normal product of carboxylase degradation, resulting in regeneration of free biotin. The encoded protein has also been shown to have biotinyl transferase activity. Mutations in this gene are associated with biotinidase deficiency. Multiple transcript variants encoding different isoforms have been described. [provided by RefSeq, Aug 2013]

GeneCards Summary for BTD Gene

BTD (Biotinidase) is a Protein Coding gene. Diseases associated with BTD include Biotinidase Deficiency and Multiple Carboxylase Deficiency. Among its related pathways are Metabolism and Vitamin digestion and absorption. GO annotations related to this gene include hydrolase activity, acting on carbon-nitrogen (but not peptide) bonds and biotin carboxylase activity. An important paralog of this gene is VNN1.

UniProtKB/Swiss-Prot for BTD Gene

  • Catalytic release of biotin from biocytin, the product of biotin-dependent carboxylases degradation.

  • Biotinidase deficiency (BTD deficiency) [MIM:253260]: 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. {ECO:0000269 PubMed:10206677, ECO:0000269 PubMed:9099842, ECO:0000269 PubMed:9654207}. Note=The disease is caused by mutations affecting the gene represented in this entry.
