Abstract

Many mismatch repair (MMR) gene disease-causing mutations identified in cancer patients result in aberrant messenger RNA (mRNA) splicing. However, mRNA assay interpretation can be complicated by the existence of naturally occurring alternative mRNA transcripts, most of which have not been formally described or fully characterized. Here, we provide a comprehensive catalogue of all MMR transcripts described to date, and a review of MMR nucleotide variants associated with an apparent upregulation of alternatively spliced transcripts. This work sets reference starting points for designing and interpreting MMR RNA analyses. Our database and literature searches retrieved 30 MLH1, 22 MSH2, 4 MSH6 a..
