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.

Maroteaux-Lamy syndrome

[märōtō′ lämē′]
Etymology: Pierre Maroteaux, French physician, b. 1926; Maurice Emile Joseph Lamy, French physician, 1895-1975
a mucopolysaccharidosis characterized biochemically by the predominance of the mucopolysaccharide dermatan sulfate in the urine and the presence of coarse granules in the leukocytes and clinically by Hurler-like signs with normal intelligence. There are three clinical forms: the severe or classic form shows Hurler-like symptoms (see Hurler's syndrome); the intermediate form has the same phenotype as pseudo-Hurler polydystrophy; and the mild form is difficult to distinguish from the Scheie's syndrome. Also called mucopolysaccharidosis VI.

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.
