Overview
Winchester syndrome in a rare congenital connective tissue disease.
Historical perspective
It was first described in 1969.
Pathophysiology
In 2005 a patient with Winchester syndrome was shown to have mutations in the matrix metalloproteinase 2 (MMP2) gene.[1] A 2006 study showed other mutations in the same gene, and observed that Winchester syndrome is probably part of a continuum that also includesTorg syndrome and nodulosis-arthropathy-osteolysis syndrome (NAO).[2]
Differentiating from other diseases
Winchester syndrome should be differentiated from rheumatoid arthritis.[3]
Diagnosis
The main characteristics are short stature, marked contractures of joints, opacities in the cornea, a coarse face, dissolution of the carpal and tarsal bones (in the hands and feet respectively) and osteoporosis. Appearances resembled rheumatoid arthritis. Increased uronic acid was demonstrated in cultured fibroblasts from the skin and to a lesser degree in both parents. Despite initial tests not showing increased mucopolysaccharide excretion, the disease was regarded as a mucopolysaccharidosis.[3]
