Genomic structure of the human ING1 gene and tumor-specific mutations detected in head and neck squamous cell carcinomas.

We characterized the genomic structure of the human ING1 gene, a candidate tumor suppressor gene, and found that the gene has three exons. We also demonstrated that four mRNA variants were transcribed from three different promoter regions. Of 34 informative cases of head and neck squamous cell carcinoma, 68% of tumors showed loss of heterozygosity at… (More)
