Gene Gene information from NCBI Gene database.
Entrez ID 3425
Gene name Alpha-L-iduronidase
Gene symbol IDUA
Synonyms (NCBI Gene)
IDAMPS1MPSI
Chromosome 4
Chromosome location 4p16.3
Summary This gene encodes an enzyme that hydrolyzes the terminal alpha-L-iduronic acid residues of two glycosaminoglycans, dermatan sulfate and heparan sulfate. This hydrolysis is required for the lysosomal degradation of these glycosaminoglycans. Mutations in th
