LOH of the VHL gene. LOH was analyzed at the heterozygous point mutation G/C of the intron 1 splice donor site and at the SNP A/G of the exon 3 of the VHL gene using a quantitative genotyping method. Comparison of cancerous tissue (T) and the peripheral blood (B) of the SCC patient indicated that the cancerous tissue had lost the mutant C allele (arrow) and the SNP A allele (arrow).
