What's a GeneRIF?
  1. study provides evidence for two novel candidate genes, SPG7 and RASGEF1B, associating with white coat effect
    Title: Genome-wide association study of white-coat effect in hypertensive patients.
  2. We show that knockdown of the expression of mcircRasGEF1B reduces LPS-induced ICAM-1 expression. Additionally, we demonstrate that mcircRasGEF1B regulates the stability of mature ICAM-1 mRNAs.
    Title: Inducible RasGEF1B circular RNA is a positive regulator of ICAM-1 in the TLR4/LPS pathway.
  3. As an addition to PRKG2 and RASGEFIB genes, we propose to include BMP3 gene as the principal determinant of the observed common phenotype.

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.
