Evidence summary

Decision support

Since the 2023 report, the consensus for TP53 c.589G>A has moved from uncertain significance to likely pathogenic. That reading rests on 11 submissions at strong review confidence, reviewed by expert panel. That crosses the clinically actionable boundary, so management guidance issued on the original interpretation may no longer be the right guidance. 2 records on file carry this variant and have not yet been reassessed.

Composed from the structured fields of the records cited on this page. Requires clinical verification before it informs any decision.
