Genes affected

GBX1 (HGNC:4185): (gastrulation brain homeobox 1) Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of nervous system development and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within adult walking behavior; neuron differentiation; and proprioception. Predicted to be part of chromatin. Predicted to be active in nucleus.
