A novel mutation in the matrix metallopeptidase 2 coding gene associated with intrafamilial variability of multicentric osteolysis, nodulosis, and arthropathy.
We characterize the clinical, radiographic and molecular findings in all individuals with molecularly proven MONA from the present cohort and previous reports, and provide a comprehensive review of the MMP2 related disorders.
The two well-described osteolysis syndromes associated with matrix metalloproteinase-2 deficiency and mutations in the metalloproteinase-2 gene are Torg-Winchester syndrome and nodulosis-arthropathy-osteolysis variant.
We questioned whether sporadic idiopathic multicentric osteolysis with nephropathy is allelic with nodulosis-arthropathy osteolysis syndrome and undertook sequence analysis of the matrix metalloproteinase 2 gene in three unrelated affected boys.
