Another characteristic is the development of arthritis in adulthood. Causes, incidence, and risk factors Return to top Alkaptonuria is an autosomal recessive inherited disorder. In affected individuals, an amino acid known as tyrosine is not properly metabolized, due to a defect in an enzyme called homogentisic acid oxidase. Because of the defect, homogentisic acid is excreted in the urine and turns a brown color upon exposure to air. This is the result of a dark pigment with an ochre color (earthy red or yellow), which led to the name ochronosis. The bones and cartilage of the body can be brown colored. Symptoms Return to top Infant/child: Family history of alkaptonuria Urine in diaper may darken after several hours (can become almost black) Adult: Progressive arthritis, especially of the spine

ALKAPTONURIA: CASE REPORT AND REVIEW OF THE LITERATURE M. Al-Essa, MD; L. Al-Shamsan; M.S. Rashed, PhD ; P.T. Ozand, MD PhD Alkaptonuria (McKusick 203500) is a rare metabolic disease characterized by a triad of homogentisic aciduria, arthritis and ochronosis. It enjoys the historic distinction of being one of the first conditions in which mendelian recessive inheritance was proposed and is also one of the conditions in the charter of group of inborn errors of metabolism. It is of interest to note that the disease was identified in 1500 BC in an ancient egyptian mummy. The manifestations are urine that turns dark on standing and alkalinization due to excretion of excessive amounts of homogentisic acid, large joint arthritis and black ochronotic pigmentation of cartilage and collagenous tissue. This disease is unusually frequent in Slovakia and the Dominican Republic. More than 126 patients have been reported from Czechoslovakia, 108 from Germany, and 90 from the United States. In countries of the Middle East, the disease was first reported from Lebanon in 1958 and from Sudan in 1965.
