In inflamed mucosa, both with and without H. pylori infection, GKN1 levels decrease, while the protein is absent in gastric cancer. The measurement of circulating GKN1 concentration, the protein itself or its mRNA in gastric tissue could be useful for the early diagnosis of cancer. [review]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
