Genes affected

L3MBTL1 (HGNC:15905): (L3MBTL histone methyl-lysine binding protein 1) This gene represents a polycomb group gene. The encoded protein functions to regulate gene activity, likely via chromatin modification. The encoded protein may also be necessary for mitosis. Alternatively spliced transcript variants encoding different isoforms have been identified.[provided by RefSeq, Sep 2010]
