Hereditary Central Nervous System Tumours Panel

Clinical Decription:
A proportion of brain tumours are caused by an inherited cancer predisposition. Individuals who have personal and family histories of associated cancers (which includes but is not limited to, brain tumours, Li-Fraumeni-associated tumours, Lynch syndrome-associated cancers) may be eligible for genetic testing. Please consult the Cancer Care Ontario document outlining eligibility for genetic testing for hereditary CNS cancer (https://www.cancercareontario.ca/en/guidelines-advice/types-of-cancer/70161) and/or contact the lab for additional information. Note: This is a blood test for individuals with clinical and family histories suggestive of an inherited cancer syndrome. It is not a tumour test for somatic gene variants that provide information about diagnostics, prognostics or therapeutics.
