Understanding Multicentric Osteolysis Nephropathy: A Rare Skeletal Disorder with Renal Involvement

Introduction to Multicentric Osteolysis Nephropathy

Multicentric osteolysis nephropathy is a rare condition characterized by aggressive bone destruction, mainly affecting carpal and tarsal bones.​ It is often associated with progressive kidney disease.​

Overview of Multicentric Osteolysis Nephropathy

Multicentric osteolysis nephropathy, also known as multicentric carpo-tarsal osteolysis syndrome (MCTO), is a rare skeletal disorder primarily characterized by aggressive bone destruction affecting the carpal and tarsal bones.​ It is often accompanied by progressive nephropathy with renal involvement. The molecular pathways underlying this condition are not fully understood, but it is commonly associated with MAFB mutations.​ Clinical manifestations include crippling joint deformities and skeletal abnormalities in the hands and feet.​
