Figure 1From: Mutation analysis of genes in the EGFR pathway in Head and Neck cancer patients: implications for anti-EGFR treatment responseSequencing result of two HNSCC patients. A: EGFR exon 20p results in a T > C mutation at nucleotide 2354 and B: EGFR exon 21 displays at nucleotide 2508 C > T. Both mutations result in a silent nucleotide polymorphism, T785T and R836R for exon 20 and exon 21 respectively.Back to article page
