Disease Associations

Mucopolysaccharidosis 2 (MPS2) [MIM:309900]: An X-linked lysosomal storage disease characterized by intracellular accumulation of heparan sulfate and dermatan sulfate and their excretion in urine. Most children with MPS2 have a severe form with early somatic abnormalities including skeletal deformities, hepatosplenomegaly, and progressive cardiopulmonary deterioration. A prominent feature is neurological damage that presents as developmental delay and hyperactivity but progresses to mental retardation and dementia. They die before 15 years of age, usually as a result of obstructive airway disease or cardiac failure. In contrast, those with a mild form of MPS2 may survive into adulthood, with attenuated somatic complications and often without mental retardation. {ECO:0000269PubMed:10215411, ECO:0000269PubMed:10220152, ECO:0000269PubMed:10447264, ECO:0000269PubMed:10671065, ECO:0000269PubMed:11015461, ECO:0000269PubMed:11683780, ECO:0000269PubMed:11731225, ECO:0000269PubMed:12655569, ECO:0000269PubMed:12794697, ECO:0000269PubMed:1284597, ECO:0000269PubMed:1303211, ECO:0000269PubMed:16699754, ECO:0000269PubMed:7581397, ECO:0000269PubMed:7599640, ECO:0000269PubMed:7728156, ECO:0000269PubMed:7866405, ECO:0000269PubMed:7887413, ECO:0000269PubMed:7981716, ECO:0000269PubMed:8281149, ECO:0000269PubMed:8566953, ECO:0000269PubMed:8664909, ECO:0000269PubMed:8830188, ECO:0000269PubMed:8940265, ECO:0000269PubMed:9222763, ECO:0000269PubMed:9266380, ECO:0000269PubMed:9375851, ECO:0000269PubMed:9452044, ECO:0000269PubMed:9501270, ECO:0000269PubMed:9660053, ECO:0000269PubMed:9762601, ECO:0000269PubMed:9875019, ECO:0000269PubMed:9921913, ECO:0000269PubMed:9950361}.
