The proband was a 62-year-old man with ureter cancer. He had a history of metachronous colorectal and gastric cancer. Immunohistochemical staining showed the absence of both MSH2 and MSH6 proteins in the ureter cancer and other available cancer tissue specimens. Genetic testing was conducted to identify the causative genes of hereditary gastrointestinal cancer syndromes including mismatch repair genes. We detected a germline variant, c.2635-3delC, within the splice acceptor site of exon 16, in the MSH2 gene. To investigate whether this variant affected splicing of the gene, RNA sequencing was performed using blood samples. We observed a substantial amount of the transcripts that lacked proper splicing of intron 15 in the indexed case, whereas, a very low amount of such aberrant transcripts was detected in the controls, strongly indicating an association between the variant and splicing defect. These results indicate that MSH2 c.2635-3delC affects normal splicing and might be a cause of Lynch syndrome.
