Genes affected

GSX2 (HGNC:24959): (GS homeobox 2) Enables DNA-binding transcription factor activity, RNA polymerase II-specific and sequence-specific double-stranded DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including nervous system development; positive regulation of Notch signaling pathway; and regulation of respiratory gaseous exchange by nervous system process. Located in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]
