Disease
IDUA_HUMAN Hurler-Scheie syndrome;Hurler syndrome;Scheie syndrome. Defects in IDUA are the cause of mucopolysaccharidosis type 1H (MPS1H) [MIM:607014; also known as Hurler syndrome. MPS1H is a severe form of mucopolysaccharidosis type 1, a rare lysosomal storage disease characterized by progressive physical deterioration with urinary excretion of dermatan sulfate and heparan sulfate. Patients with MPS1H usually present, within the first year of life, a combination of hepatosplenomegaly, skeletal deformities, corneal clouding and severe mental retardation. Obstructive airways disease, respiratory infection and cardiac complications usually result in death before 10 years of age.[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] Defects in IDUA are the cause of mucopolysaccharidosis type 1H/S (MPS1H/S) [MIM:607015; also known as Hurler-Scheie syndrome. MPS1H/S is a form of mucopolysaccharidosis type 1, a rare lysosomal storage disease characterized by progressive physical deterioration with urinary excretion of dermatan sulfate and heparan sulfate. MPS1H/S represents an intermediate phenotype of the MPS1 clinical spectrum. It is characterized by relatively little neurological involvement, but most of the somatic symptoms described for severe MPS1 develop in the early to mid-teens, causing considerable loss of mobility. Defects in IDUA are the cause of mucopolysaccharidosis type 1S (MPS1S) [MIM:607016; also known as Scheie syndrome. MPS1S is a mild form of mucopolysaccharidosis type 1, a rare lysosomal storage disease characterized by progressive physical deterioration with urinary excretion of dermatan sulfate and heparan sulfate. Patients with MPS1S may have little or no neurological involvement, normal stature and life span, but present development of joints stiffness, mild hepatosplenomegaly, aortic valve disease and corneal clouding.
