Important Resources for Rhabdoid Tumor Predisposition Syndrome:
Rhabdoid Tumor Predisposition Syndrome (RTPS), first recognized in the 2007 revision of the World Health Organization Classification of Tumors of the Central Nervous System (4th edition), is characterized by a germline mutation in the INI1 gene (chromosome 22q11.2) and manifested by a marked predisposition toward the development of malignant rhabdoid tumors of infancy and early childhood. The atypical teratoid/rhabdoid tumor (AT/RT) is by far the most common CNS malignacy associated with this syndrome. Up to one-third of AT/RTs are thought to arise in the setting of RTPS. Other tumors that have also been reported in association with this syndrome include: medulloblastoma, choroid plexus carcinoma, primitive neuroectodermal tumors (PNETs), and malignant rhabdoid tumor of the kidney. Because of the risks associated with RTPS, it is recommended that the germline status of the INI1 allele be investigated in each new case of AT/RT.[1]
