Analysis of a single nucleotide polymorphism in codon 388 of the FGFR4 gene in malignant gliomas

The FGFR4 codon 388 polymorphism (Arg(388), Arg/Gly(388) or Gly(388)) was determined in glioblastoma multiforme (GBM), anaplastic astrocytomas (AA), diffuse astrocytomas (DA), and control muscles. Arg(388) was rare in AA, GBM, muscles, and was absent in DA. The Arg/Gly(388) and the Gly(388) frequency was equal among GBM and controls. FGFR4 expression was not related to codon 388 in GBM, and no survival differences between Arg/Gly(388) and Gly(388) tumors were found. U87 cells (Arg/Gly(388)) did not show higher invasion than U138 cells (Gly(388)). This suggests that the FGFR4 codon 388 status does not play a major role in malignant gliomas.
