Li Fraumeni syndrome is associated with a loss of function mutation in p53 (FA2020 p224, p46)
p53 is a modulator at the G1/S restriction point. p53 activation in the presence of DNA damage, misfolded protein, and hypoxia leads to activation of BAK/BAX and subsequent activation of the apoptotic pathway (p208). Thus, loss of function of p53 will lead to impaired regulation of apoptosis and uninhibited cell division in cancer cells.
