Winchester syndrome is an autosomal recessive connective tissue disorder caused by mutations in the matrix metalloproteinase 2 (MMP2) gene.  A 2006 study showed other mutations in the same gene, and observed that Winchester syndrome is probably part of a continuum that also includes Torg syndrome and nodulosis-arthropathy-osteolysis syndrome (NAO).
