Description : Multicentric carpotarsal osteolysis syndrome is a rare skeletal disorder, usually
presenting in early childhood with a clinical picture mimicking juvenile rheumatoid
arthritis. Progressive destruction of the carpal and tarsal bone usually occurs and
other bones may also be involved. Chronic renal failure is a frequent component of
the syndrome. Mental retardation and minor facial anomalies have been noted in some
patients. Autosomal dominant inheritance has been documented in many families (Pai
and Macpherson, 1988). See also Torg-Winchester syndrome (259600), an autosomal recessive
multicentric osteolysis syndrome.;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the MAF bZIP transcription factor B gene (MAFB, 608968.0001);
