Genes affected

GBX2 (HGNC:4186): (gastrulation brain homeobox 2) Enables sequence-specific double-stranded 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 several processes, including branching involved in blood vessel morphogenesis; nervous system development; and neural crest cell migration. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]
