Genes affected
STAG3 (HGNC:11356): (STAG3 cohesin complex component) The protein encoded by this gene is expressed in the nucleus and is a subunit of the cohesin complex which regulates the cohesion of sister chromatids during cell division. A mutation in this gene is associated with premature ovarian failure. Alternate splicing results in multiple transcript variants encoding distinct isoforms. This gene has multiple pseudogenes. [provided by RefSeq, Apr 2014]
CASTOR3P (HGNC:29954): (CASTOR family member 3, pseudogene) Predicted to be involved in cellular response to L-arginine and negative regulation of TORC1 signaling. Predicted to be active in cytosol. [provided by Alliance of Genome Resources, Apr 2022]
