Fibroblast growth factor receptor 4 single nucleotide polymorphism Gly388Arg in head and neck carcinomas

Figure 1 Polymerase chain reaction-restriction fragment length polymorphism analysis of fibroblast growth factor receptor 4 G388 gene. Five individual tissue specimen of Head and Neck Squmous Cell Carcinoma are presented. Line 2 shows a homozygote carrier for the Glycine allele, the dominant form of the fibroblast growth factor receptor 4 (FGFR4). Lane 1, 3 and 5 show a heterozygote carrier of the FGFR4 with both alleles glycine388 and arginine388. Lane 4 shows a homozygous carrier for the arginine allele.
