Résumé
Camptodactyly-arthropathy-coxa vara-pericarditis (CACP) syndrome (MIM# 208250) is a rare monogenic disorder, characterized by early onset of camptodactyly, progressive coxa vara, bilateral arthropathy and constrictive pericarditis. The syndrome is caused by biallelic loss-of-function variants in PRG4. Deficiency of PRG4 results in progressive worsening of joint deformity with age. Thirteen individuals with CACP syndrome from eight consanguineous Indian families were evaluated. We used exome sequencing to elucidate disease-causing variants in all the probands. These variants were further validated and segregated by Sanger sequencing, confirming the diagnosis of CACP syndrome in them. Seven females and six males aged 2-23 years were studied. Camptodactyly (13/13), coxa vara (11/13), short femoral neck (11/13) and arthritis in large joints (12/13) [wrists (11/13), ankle (11/13), elbow (10/13) and knee (10/13)] were observed commonly. Five novel disease-causing variants (c.3636G>T, c.1935del, c.1134dup, c.1699del and c.962T>A) and two previously reported variants (c.1910_1911del and c.2816_2817del) were identified in homozygous state in PRG4. We describe the phenotype and mutations in one of the large cohorts of patients with CACP syndrome, from India.
