Our results support observation in the COSMIC Cell Lines Project (http://cancer.sanger.ac.uk) where amplifications of LAIR2, KLRC1, NCR1, NCR3, KLRC2, C3, and C4 were reported in various cancer cell lines such as lung carcinoma, adenocarcinoma, gastric choriocarcinoma, and pancreatic cancer cell lines. This evidence concerns the gene C3 and familial pancreatic carcinoma.
