In order to compare our findings with those previously reported, the results of MMR protein expression using IHC and MSI analysis from a total of 118 reported brain tumors in patients with CMMRD syndrome have been reviewed and are specified in Table 4 [2,7,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66]. This evidence concerns the gene MRC1 and brain neoplasm.
