Funkcija

Ovaj gen kodira enzim koji razgrađuje heparan sulfat hidrolizom krajnjih ostataka N-acetil-D-glukozamina u N-acetil-alfa-D-glukozaminidima.

Klinički značaj

Defekti u ovom genu uzrok su mukopolisaharidoza tipa IIIB (MPS-IIIB), takođe poznat kao Sanfilippov sindrom B. Ovu bolest karakterizira akumulacija lizosoma i izlučivanje heparan-sulfata urinom.
