Comparative analysis of mutation frequency of coding and non coding short mononucleotide repeats in mismatch repair deficient colorectal cancers.

Abstract excerpt

Coding repeats are usually short mononucleotide tracts (SMT) of 10 or less base pairs in size. A number of such sequences contained in genes suspected to play a role in human carcinogenesis have been found to be mutated in mismatch repair deficient tumors (MSI-H cancers). Because of the high background of instability characterizing these cancers and in the absence of functional criteria, the significance of most...
