A Novel MLH1 Initiation Codon Mutation (c.3G>T) in a Large Chinese Lynch Syndrome Family with Different Onset Age and mRNA Expression Level

Figure 4

The relative mRNA level of MLH1 in these family members with or without MLH1 mutation. III:1, II:2, and III:3 are patients, II:5, IV:1, and IV:4 are unaffected carriers, III:5 and II:1 are non-carriers in this family, and normal control is a non-carrier of MMRs gene with no blood relationship to this family. The levels of MLH1 in patients were lower than those with wild type MLH1 or unaffected carriers.
