Mutations or small insertions or deletions that results in truncation, frameshift, stop codon loss, or stop codon gain will also be considered deleterious irrespective of their presence in the aforementioned databases unless previously characterized to be benign. Copy number losses or disruption by fusion will also be considered deleterious irrespective of their presence in the aforementioned databases. Gene amplifications or variants of unknown significance will not be eligible for inclusion.\n\n NOTE: Genetic testing results from a CLIA certified lab that confirm one of the following: high LOH in tissue, HR mutation in tissue or germline mutation in blood are required and can be used to meet eligibility.
