Camptodactyly-Arthropathy-Coxa Vara-Pericarditis (CACP) Syndrome Masquerading as Juvenile Idiopathic Arthritis: A Case Series with A Novel PRG Variant and Emphasis on Bone Health

2026-05-28

Abstract excerpt

<title>Abstract</title> <p> <bold>Background</bold> Camptodactyly–arthropathy–coxa vara–pericarditis syndrome is a rare autosomal recessive disorder caused by loss-of-function variants in the proteoglycan 4 gene, which encodes lubricin. It is frequently misdiagnosed as juvenile idiopathic arthritis, leading to prolonged immunosuppressive therapy. <bold>Case presentation</bold> : We report two unrelated boys b...
