An old study back in 1999 suggested that CHEK2 may be a Li-Fraumeni Syndrome gene.1 However, a subsequent report in 2002 clearly refuted this original assertion, and based on additional data and analysis concluded that “… it is very unlikely that CHEK2 is an alternative Li-Fraumeni Syndrome susceptibility gene.”2 Another subsequent report in 2008 based on additional information concluded that “… it is no longer reasonable to consider CHEK2 mutations to be a cause of Li-Fraumeni Syndrome.”3 Based on this information, CHEK2 is absolutely not considered a gene that causes Li-Fraumeni Syndrome.
