Gm7609 - predicted pseudogene 7609

This gene is one of several duplicated genes in a repeat cluster in the homogeneously staining region (HSR) of chromosome 1. It is an Sp100-rs gene copy, which arose by duplication following the fusion of the Csprs (component of Sp100-rs) gene and the 5' part of the Sp100 (nuclear antigen Sp100) gene. The coding sequence of this gene is intact compared to that of the Csprs gene, and therefore NCBI represents this as a protein-coding gene. However, it is also possible to interpret this fusion gene as a pseudogene of the Sp100 gene. It is unknown if this gene produces a protein in vivo. [provided by RefSeq, Mar 2011]
