Mutations in the transforming growth factor beta-type II receptor (TGFbeta RII) gene have been detected in several types of human cancers that represent the phenotype of genomic instability. The TGFbeta RII gene has been mapped to chromosome 3p, on which loss of heterozygosity (LOH) was frequently detected in both small cell lung carcinoma (SCLC) and non-small cell lung carcinoma (NSCLC). To investigate whether the TGFbeta RII gene on 3p22 is inactivated in lung cancers, we examined 35 sporadic lung cancers (15 SCLC and 20 NSCLC) with LOH on 3p for mutations of the TGFbeta RII gene. We previously produced eight intron based primer pairs for mutational analysis of the entire coding region of the TGFbeta RII gene. Using these primers, we screened for mutations of the TGFbeta RII gene by polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP) analysis. A mutation was detected in a case of SCLC: one base insertion in the polyadenine tract of exon 3. This tumor showed the replication error (RER) phenotype. There were no mutations in exons 1, 2, 4, 5, 6 and 7. These results indicate that the polyadenine tract is a mutational hot spot in the TGFbeta RII gene in RER positive tumors, and that TGFbeta RII mutations occur rarely in lung cancers with LOH on chromosome 3p.
