K1 Urinary glycosaminoglycan K1 Vestronidase alfa AB Mucopolysaccharidosis (MPS) VII is an ultra-rare, autosomal-recessive, metabolic disease caused by a deficiency of β-glucuronidase, a lysosomal enzyme that hydrolyzes glycosaminoglycans (GAGs), including dermatan sulfate (DS), chondroitin sulfate, and heparan sulfate (HS). β-glucuronidase deficiency leads to progressive accumulation of undegraded GAGs in lysosomes of affected tissues, which may cause hydrops fetalis, short stature, hepatosplenomegaly, and cognitive impairment. An open-label, multicenter, phase II study was conducted in 8 pediatric subjects YR 2022 FD 2022-03-09 LK http://hdl.handle.net/10668/22551 UL http://hdl.handle.net/10668/22551 LA en DS RISalud RD Apr 12, 2025
