Multiple cancer syndromes are associated with one or two genes. Broad cancer panels are not the most appropriate type of testing for evaluation. Single-gene testing may cost up to $2,000.
Continuous research on hereditary cancer genes has expanded the spectrum of many cancer syndromes. It’s important to keep in mind that additional genes may be considered for analysis in individuals that previously had single-gene testing. For example, an individual with 10 to 100 polyps may have a less severe form of FAP (called attenuated FAP or AFAP), MYH-associated polyposis (MAP), or other emerging genes becoming more associated with polyposis (PTEN, POLE, POLD1).
