PURPOSE Multiplex genetic testing, including both moderate- and high-penetrance genes for cancer susceptibility, is associated with greater uncertainty than traditional testing, presenting challenges to informed consent and genetic counseling. We sought to develop a new model for informed consent and genetic counseling for four ongoing studies. METHODS(More)
PURPOSE Clinical testing for germ-line variation in multiple cancer susceptibility genes is available using massively parallel sequencing. Limited information is available for pretest genetic counseling regarding the spectrum of mutations and variants of uncertain significance in defined patient populations. METHODS We performed massively parallel(More)
PURPOSE Adrenocortical carcinoma (ACC) is a hallmark cancer in families with Li Fraumeni syndrome (LFS) caused by mutations in the TP53 gene. The prevalence of germline TP53 mutations in children diagnosed with ACC ranges from 50-97%. Although existing criteria advocate for TP53 testing in all patients with ACC regardless of age at diagnosis, the overall(More)
