Normally, the amount of biotin in the body is regulated by dietary intake, biotin transporters (monocarboxylate transporter 1 and sodium-dependent multivitamin transporter), peptidyl hydrolase biotinidase (BTD), and the protein ligase holocarboxylase synthetase. When any of these regulatory factors are inhibited, biotin deficiency could occur. [23]
Signs and symptoms of a biotinidase deficiency (BTD) 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.
For example, a holocarboxylase synthetase (HCS) deficiency would make it harder for the body to attach biotin to other enzymes that need it, according to the National Library of Medicine. This ...
Alopecia occurs for various reasons, including genetics, autoimmune disorders where the immune system attacks hair follicles, hormonal changes, medical treatments like chemotherapy, or other factors.
Discover what this essential B vitamin can do for your body and whether you need more in your diet.
Primary biotin deficiency, meaning deficiency as a consequence of too little biotin in the diet, is rare, because biotin is contained in so many foods. Subclinical deficiency can cause mild symptoms, such as hair thinning, brittle fingernails, or skin rash, typically on the face. [2] [4]
Signs of a biotin deficiency may appear gradually, per the NIH. In the later stages, a biotin deficiency can cause: Hair thinning. Hair loss. A scaly, red rash around orifices. Dry, red eyes ...
Forms include: [citation needed] Holocarboxylase synthetase deficiency - neonatal;; Biotinidase deficiency - late onset;; If left untreated, the symptoms can include feeding problems, decreased body tone, generalized red rash with skin exfoliation and baldness, failure to thrive, seizure, coma, developmental delay, foul smelling urine, lactic acidosis, and high levels of ketones and ammonia in ...
