Nkx2-5 genetically interacts with Xrn2 because Nkx2-5(+/-)Xrn2(+/-), but neither Nkx2-5(+/-)nor Xrn2(+/-), newborns exhibited a defect in ventricular septum formation, suggesting that the association between Nkx2-5 and Xrn2 is essential for heart development.

Genetic variants regulating Xrn2 expression in cis are determinants of spontaneous lung tumor susceptibility in mice and have genetic equivalents in lung cancer susceptibility in human beings.
Title: Genetic variants cis-regulating Xrn2 expression contribute to the risk of spontaneous lung tumor.

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.
