Genetic Investigation of Cancer Predisposition

Genetic screening will be performed on DNA (and/or RNA) isolated from collected samples from affected individuals by whole exome sequencing or RNA sequencing using in-house pipeline to identify candidate sequence variants. These variants will be tested for segregation with the phenotype in other relatives (affected/unaffected). Candidate variants will be subjected to additional downstream analysis, to be guided by the actual type of gene/variant.

Inclusion criteria

• Any age
• Meets at least ONE of the following:

• Personal history (with documented diagnosis) of cancer before the age of 50
• Personal history of more than one primary cancer
• Documented diagnosis of cancer AND family history of that same cancer type or multiple other cancers that do not fit classical criteria of hereditary cancer syndromes
• Documented diagnosis of a rare cancer AND family history of rare cancers that do not fit classical criteria of hereditary cancer syndromes
• There is the same type of cancer in several generations of a family
• Documented diagnosis of multicentric cancers (e.g bilateral cancers in paired organs, or multifocal cancers in single organs) that usually occur as single lesions when presented sporadically
• Early onset cancer (before the age of 50, or breast cancer before age 45) AND family history of early onset cancer Capable of providing access to detailed medical records and family history of cancer

Exclusion criteria

• Established genetic diagnosis of a known hereditary cancer syndrome that is compatible with the clinical presentation
• Incarcerated
