In lung adenocarcinoma, 18 genes (SLCO1A2, PYROXD1, RECQL, LDHB, CMAS, KIAA0528, ETNK1, ASUN, FGFR1OP2, TM7SF3, MED21, MRPS35, KLHDC5, CCDC91, FGD4, DNM1L, YASR2, and KRAS) in 12p12.1 were found to have increased copy number and coamplified with KRAS, 88.9% (8/9) genes in our study were included. Here, RECQL is linked to lung adenocarcinoma.
