    Sujet
    This gene encodes a zinc finger transcription factor thought to play a role in the development of abducens motor neurons. Defects in this gene are a cause of Duane-radial ray syndrome (DRRS). Alternative splicing results in multiple transcript variants encoding different isoforms.,SALL4,DRRS,HSAL4,ZNF797,Epigenetics & Nuclear Signaling,Cell Biology & Developmental Biology,Stem Cells,Embryonic Stem Cells,SALL4
