Evidence summary

Decision support

Accumulated evidence now favours a more benign reading of TP53 c.784G>A than the uncertain significance interpretation issued in 2022; the current consensus is likely benign. Where the original result drove additional testing or surveillance, that basis may have weakened. One record on file carries this variant and has not yet been reassessed.
