About STAG2

Cytogenetic location: Xq25 Genomic coordinates (GRCh38): X:123,960,560-124,102,656 (from NCBI)

This gene has 29 transcripts (splice variants), 203 orthologues, 2 paralogues and is associated with 138 phenotypes. Ubiquitous expression in thyroid (RPKM 24.4), bone marrow (RPKM 22.3) and 25 other tissues.

Summary

The protein encoded by this gene is a subunit of the cohesin complex, which regulates the separation of sister chromatids during cell division. Targeted inactivation of this gene results in chromatid cohesion defects and aneuploidy, suggesting that genetic disruption of cohesin is a cause of aneuploidy in human Cancer. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2013]
