What is the deficiency disease biotin ?

Question

Hi,
biotin deficiency is a rare nutritional disorder which can become serious, even fatal, if allowed to progress untreated. It can occur in people of any age, ancestry, or gender. Biotin is part of the b vitamin family. Biotin deficiency rarely occurs among healthy people because the daily requirement of biotin is low, many foods provide adequate amounts of it, intestinal bacteria synthesize small amounts of it, and the body effectively scavenges and recycles it from bodily waste. However, deficiencies can be caused by consuming raw egg whites over a period of months to years. The signs and symptoms of biotin deficiency are:
rashes including red, patchy ones near the mouth fine and brittle hair
hair loss or total baldness (alopecia)
anemia
birth defects (still being studied)
seborrheic dermatitis
fungal infections
hallucinations
lethargy
anorexia
mild depression, which may progress to profound fatigue and, eventually, to somnolence
generalized muscular pains (myalgias)
paresthesias.
