History

The FGFR2 gene produces a protein called fibroblast growth factor receptor 2 (FGFR2), which is involved in cell growth. Expression of FGFR2 in Iraqi breast cancer patients was the subject of this research. It was observed that FGFR2 was overexpressed in breast cancer tumors and cell lines. On the 10q26 chromosome, the FGFR2 gene has 20 exons. The FGFR2 gene has been linked to a higher risk of breast cancer in a number of studies. The relationship was confirmed by polymorphisms in FGFR2 intron 2, which increased BC susceptibility by 5–10%. The CC genotype of the SNP rs1219648 showed the lower level of the FGFr2 gene expression in both patient s and control (143.3±117.0 and 1.2±2.7, respectively) and the TT genotype showed the higher level (203.9±145.0 and 11.6±18.7). The results are shown in the table (4) and include the patients and control with the genotype rs2981582 and those with the SNP rs4563158.
