Two novel mutations in the homogentisate-1,2-dioxygenase gene identified in Chinese Han Child with Alkaptonuria.

Abstract excerpt

Alkaptonuria (AKU) is an autosomal recessive disorder of tyrosine metabolism, which is caused by a defect in the enzyme homogentisate 1,2-dioxygenase (HGD) with subsequent accumulation of homogentisic acid. Presently, more than 100 HGD mutations have been identified as the cause of the inborn error of metabolism across different populations worldwide. However, the HGD mutation is very rarely reported in Asia,...
