Histidinemia is an inherited condition characterized by elevated blood levels of the amino acid histidine, a building block of most proteins. Histidinemia is caused by the shortage (deficiency) of the enzyme that breaks down histidine. Histidinemia typically causes no health problems, and most people with elevated histidine levels are unaware that they have this condition.
