Overview

This study is being done to attempt to identify genetic mutations or other gene-based variations in adults and children who have cancer, or are likely to develop an inherited form of cancer, and potentially reduce their risk for cancer or treat the cancer earlier.

Eligibility

Inclusion Criteria:

• Individuals who have undergone clinical and/or research genetic evaluation, found to have or not have a germline genetic variant (pathogenic, likely pathogenic, variant of uncertain/unknown significance, likely benign).
• Individuals with or without a personal history of malignant or pre-malignant lesions who demonstrate: a) clinical findings suggestive of a genetic cancer susceptibility syndrome including very early age at onset, multiple primary malignancies, or other features; and/or b) family histories suggestive of a genetic cancer susceptibility syndrome, or c) other features suggesting inherited etiology of malignancy as determined by the PI.
• Family members of the above participants. Both children (with parental consent as age appropriate) and adults are eligible to participation.
• Individuals may or may not be enrolled MSK patients; probands may be referred to (or self-referred to) the study and may be enrolled at discretion of the PI and if able to provide informed consent.
• Biospecimens derived from deceased family members may be used for research in this study if consent if provided by the executor of the estate of that individual.

Exclusion Criteria:

• Patients will be excluded from this study if he/she has physical, cognitive or psychiatric conditions that interfere with ability to give meaningful informed consent.
