Ma·ro·teaux-·La·my syn·drome

(mah-rō-tō' lah'mē), [MIM*253200]
an error of mucopolysaccharide metabolism characterized by excretion of dermatan sulfate in the urine, growth retardation, lumbar kyphosis, sternal protrusion, genu valgum, usually hepatosplenomegaly, and no mental retardation; onset occurs after 2 years of age; autosomal recessive inheritance, caused by mutation in the arylsulfatase B gene (ARSB) on chromosome 5q.

Maroteaux-Lamy syndrome

(măr′ə-tō′lä-mē, mä-rô-)
A type of mucopolysaccharidosis (MPS VI) characterized by the presence of dermatan sulfate in the urine, skeletal abnormalities, corneal clouding, hearing loss, and enlargement of the liver and spleen.

mucopolysaccharidosis type 6

An autosomal recessive lysosomal storage disease (OMIM:253200) characterised by intracellular accumulation of dermatan sulfate.
Clinical findings
Abnormal growth, short stature, stiff joints, skeletal malformations, corneal clouding, hepatosplenomegaly and cardiac defects.
Molecular pathology
Defects in ARSB on chromosome 5q11-q13, which encodes arylsulfatase B, causes mucopolysaccharidosis type 6.

Because of progressive coarsening of facial features and moderate intellectual disability due to a brief intelligence quotient of 55, consistent with the diagnosis of moderate intellectual disability, biochemistry enzyme assays were performed and ruled out the diagnoses of Sanfilippo syndrome, Hurler syndrome, and Maroteaux-Lamy syndrome.

INTRODUCTION: Mucopolysaccharidosis VI (Maroteaux-Lamy syndrome, MPS VI) is a lysosomal storage disorder caused by mutations in the N-acetylgalactosamine-4-sulfatase (Arylsulfatase B, ARSB) gene, resulting in the accumulation of glycosaminoglycans (GAGs) in cells and tissues all over the body.
