Correct Answer: Hurler syndrome.
Description: Mucopolysaccharidoses
Mucopolysaccharidoses (MPS) result from abnormal degradation of glycosaminoglycans such as dermatan sulfate, keratan sulfate, heparan sulfate, and chondroitin sulfate resulting in organ accumulation and eventual dysfunction.
The mode of transmission is autosomal recessive except for MPS II, which is X-linked. In general, MPS are progressive disorders, characterized by the involvement of multiple organs, including the
brain, liver, spleen, heart, and blood vessels; many are associated with coarse facial features, clouding of the cornea, and mental retardation.
