Genes affected

MGA (HGNC:14010): (MAX dimerization protein MGA) Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in cell fate specification and positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within cellular response to leukemia inhibitory factor. Part of MLL1 complex. [provided by Alliance of Genome Resources, Apr 2022]
