| NOTE |
Alkaptonuria (AKU) is a rare autosomal recessive disorder of both historical and medical interest. It represents a classical example of a discrete biochemical lesion resulting from a single gene deficiency that gives rise to a degenerative disease.
The HGD gene comprises 14 exons and spans 54.363 bp. The functional HGD protein is a hexamer, organized as a dimer of trimers.
The HGD-mutation database includes all HGD variants and AKU patients reported so far. Database also incorporates the data in the original AKU mutation database located in Madrid (updated last in 2001), in agreement with Prof. Santiago Rodriguez de Cordoba.
