al·kap·ton·uria (al-kap″to-nuґre-ə) an autosomal recessive aminoacidopathy caused by mutations in the HGD gene (locus: 3q21-q23), which encodes homogentisate 1,2-dioxygenase; enzyme deficiency results in accumulation of homogentisic acid. Manifestations include elevated concentrations of homogentisic acid in urine, which darkens on standing or undergoing alkalinization; ochronosis; and arthritis.
