Parc et al. demonstrated that 34% of young patients with endometrial cancer (median age 46) were associated with MI, 57% of the MI positive group showed an absence of hMLH1 expression, 19% showed an absence of hMLH2 expression, and 23.8% demonstrated a normal expression of both proteins, while 9.5% of all patients were diagnosed with Lynch syndrome [59]. This evidence concerns the gene MLH1 and Lynch syndrome.
