Homogentisic acid induces aggregation and fibrillation of amyloidogenic proteins

Biochimica et Biophysica Acta (BBA) - General Subjects, 2017
Alkaptonuria (AKU) is an ultra-rare inborn error of metabolism characterized by homogentisic acid (HGA) accumulation due to a deficient activity of the homogentisate 1.2-dioxygenase (HGD) enzyme. This leads to the production of dark pigments that are deposited onto connective tissues, a condition named 'ochronosis' and whose mechanisms are not ...

Arthroplasty for the treatment of joint degeneration caused by ochronosis in two cases

Acta Orthopaedica et Traumatologica Turcica, 2020
Ochronosis is a rare metabolic disease caused by the deficiency of the homogentisic acid oxidase enzyme. With increasing age, accumulation of pigment deposits of homogentisic acid in the joint cartilage results in ochronotic osteoarthritis.
