Origin and predisposition
Variants present from early development can be part of a person’s genetic constitution. Some are associated with cancer predisposition; many are not. Interpretation depends on the particular variant and its evidence.
Classification can change
Classification, including uncertain significance, depends on evidence, methods and assessment date. Reclassification reflects a change in interpretation and does not mean that the person’s DNA has changed.
Interpret in context
Predisposition means increased possibility, not inevitable disease. Family history and appropriate counselling contribute to interpretation. A database annotation cannot replace that context.
Interpretation limits
A variant of uncertain significance is not equivalent to a proven pathogenic variant.
