Summaries for Ochronosis

NIH Rare Diseases : 54 Ochronosis is the bluish-black discoloration of certain tissues, such as the ear cartilage, the ocular (eye) tissue, and other body locations. It often occurs in individuals with alkaptonuria, a metabolic disorder; it can also occasionally occur from exposure to various substances. Alkaptonuria is caused by a mutation in the HGD gene, which results in the accumulation and deposition of homogentisic acid (HGA) in cartilage, causing the characteristic coloring of ochronosis. The affected tissue becomes weak and brittle with time, leading to chronic inflammation, degeneration, and osteoarthritis. Alkaptonuria is inherited in an autosomal recessive manner. When ochronosis is due to exposure to substances (called exogenous ochronosis), the condition is not inherited.

MalaCards based summary : Ochronosis is related to alkaptonuria and exogenous ochronosis, and has symptoms including muscle weakness, polydipsia and dry skin. An important gene associated with Ochronosis is HGD (Homogentisate 1,2-Dioxygenase), and among its related pathways/superpathways are Histidine, lysine, phenylalanine, tyrosine, proline and tryptophan catabolism and Tyrosine metabolism. The drugs Nitisinone and tyrosine have been mentioned in the context of this disorder. Affiliated tissues include eye, skin and prostate.

Disease Ontology : 12 A connective tissue disease characterized by bluish-brown discoloration of connective tissues that develops from the deposition of homogentisic acid and subsequent oxidation and polymerization reactions.
