Genes affected

IRX6 (HGNC:14675): (iroquois homeobox 6) Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific; DNA-binding transcription repressor activity, RNA polymerase II-specific; and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in cell development; neuron differentiation; and regulation of transcription, DNA-templated. Predicted to act upstream of or within detection of visible light; negative regulation of transcription, DNA-templated; and retina morphogenesis in camera-type eye. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]
