Alkaptonuria: An Inborn Error of Amino Acid Metabolism
ثبت نشده
چکیده
Background: Alkaptonuria (AKU) is a rare hereditary metabolic disorder that occupies a unique position in the history of medical and biochemical genetics because it was the first human metabolic disorder to be interpreted as genetically determined. This condition is characterized by deficiency of HGAO, an enzyme that is mainly found in hepatocytes. The medical interest in alkaptonuria stems from its association with ochronosis, arthropathy and homogentisicaciduria.

Alkaptonuria is a rare inborn error of metabolism, identified over a century ago. But its basic pathomechanism (i.e. ochronosis) is still not completely explained. Though clinical onset of osteoarthropathy and complications from other organs (including: heart and blood vessels, skin, eyes, kidneys) occurs at adult age, the symptoms are progressive, cause severe pains and significantly limit eve...
متن کاملStructural and functional analysis of mutations in alkaptonuria.
Alkaptonuria (AKU), the prototypic inborn error of metabolism, was the first human disease to be interpreted as a Mendelian trait by Garrod and Bateson at the beginning of last century. AKU results from impaired function of homogentisate dioxygenase (HGO), an enzyme required for the catabolism of phenylalanine and tyrosine. With the novel 7 AKU and 22 fungal mutations reported here, a total of ...
متن کاملAlkaptonuria: A case report
Alkaptonuria is a rare inborn error of metabolism with autosomal recessive inheritance with a mutation in homogentisate 1,2-dioxygenase. It results in accumulation of homogentisic acid in connective tissues (ochronosis). Most common ocular manifestations are bluish-black discoloration of the conjunctiva, cornea, and sclera. In this case report, a 39-year-old Indian male patient with additional ...
