Q. What causes a lack of vitamin H?

Answer

Biotin insufficiency is most commonly brought on by a lack of the enzyme biotinidase (BTD). Biotin deficiency (BTD) is caused by a lack of biotin because of a rare hereditary condition. A change in the BTD gene is the root of the problem. This gene provides instructions for making biotinidase an enzyme required by the body to get biotin from meals.Babies with BTD typically begin displaying symptoms within the first few months of life. A few of the most typical signs are:lack of muscular tone (hypotonia)seizureshair thinning or baldingeczemaDelay in developmentBiotinidase activity may also be checked in amniotic fluid samples taken before birth.
