Preferred Label : Multicentric osteolysis, nodulosis, and arthropathy;
Symbol : MONA;
CISMeF acronym : MONA;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : Osteolysis, hereditary multicentric; Torg-winchester syndrome; Torg syndrome; Nodulosis-arthropathy-osteolysis syndrome; Nao syndrome; Al-aqeel sewairi syndrome;
Description : Zankl et al. (2007) defined what they considered to be a continuous clinical spectrum
involving Torg syndrome, Winchester syndrome (277950), and NAO syndrome. Torg syndrome
is characterized by the presence of multiple, painless, subcutaneous nodules and mild
to moderate osteoporosis and osteolysis that is usually limited to the hands and feet.
Radiographically, the osteolysis is accompanied by a characteristic widening of the
metacarpal and metatarsal bones. Winchester syndrome presents with severe osteolysis
in the hands and feet and generalized osteoporosis and bone thinning, similar to NAO,
but subcutaneous nodules are characteristically absent. Various additional features
including coarse face, corneal opacities, gum hypertrophy, and EKG changes have been
reported. NAO syndrome, which has only been described in patients from Saudi Arabia,
is generally more severe, with multiple prominent and painful subcutaneous nodules,
massive osteolysis in the hands and feet, and generalized osteoporosis. Coarse face
and body hirsutism are additional features.;
