Genes affected

NKX3-2 (HGNC:951): (NK3 homeobox 2) Enables sequence-specific double-stranded DNA binding activity. Predicted to be involved in cell differentiation; negative regulation of chondrocyte differentiation; and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including animal organ development; embryonic skeletal system development; and intestinal epithelial cell development. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]
