Candidate XIC region in human and mouse. A schematic of the gene content and organization across the candidate X-Inactivation Center (XIC) of human (72.5–73.4 Mb in hg19) and the orthologous region of mouse is shown. RefSeq genes orthologous between human and mouse (gray and colored boxes). (Black) Genes that are not orthologous. (Arrows) Indicate the direction of transcription of each gene. The human NCRNA00183 is also referred to as JPX or ENOX, while mouse RefSeq 2010000I03Rik corresponds to Jpx. Mouse RefSeq 2010000l03Rik is now referred to as Enox. The human NCRNA00182 is also referred to as FTX, while in mouse RefSeq B230206F22Rik corresponds to Ftx. Human NCRNA00182 is now referred to as MIR374AHG.
