The allelic or genotypic frequencies of the rs28362491 (located in the promoter region of NFKB1), rs230521 (NFKB1 intron 4), and rs4648068 (NFKB1 intron 12) polymorphisms in the patients with GC were significantly different from those in the healthy controls.
Homozygous rs4648068 GG was associated with an increased risk of gastric cancer, especially for the lymph node status and serosa invasion in Han Chinese population.
The allelic or genotypic frequencies of the rs28362491 (located in the promoter region of NFKB1), rs230521 (NFKB1 intron 4), and rs4648068 (NFKB1 intron 12) polymorphisms in the patients with GC were significantly different from those in the healthy controls.
To identify markers contributing to the genetic susceptibility to GC, we analyzed 15 single nucleotide polymorphisms (SNPs, rs28362491, rs3774932, rs1598856, rs230531, rs230530, rs230528, rs230521, rs230498, rs230539, rs1005819, rs3774956, rs4648055, rs3774964, rs4648068, and rs3774968) in the genomic region containing NFKB1.
