General Discussion

Alkaptonuria is a rare hereditary disorder in which homogentisic acid accumulates in the body and destroys connective tissue and bone, creating a condition called ochronosis. Symptoms generally begin during the second or third decade of life, and may progress to incapacitating bone and joint disease by the sixth to eighth decade of life. The condition is characterized by the excretion of large volumes of dark colored urine. The darkened urine is the result of the exposure to the air of homogentisic acid that accumulates in the urine.
