Given the reported long-range cis-inactivating effect of the XIST gene in early embryonic development and the lack of requirement of X-chromosome-specific elements for propagating the inactive state, there exists the possibility of cis inactivation of autosomal material after de novo translocation to an inactive X chromosome ( Xi ) in differentiated cells .
 ( DNA: XIST gene, None) , ( DNA: inactive X chromosome, None) , ( DNA: Xi, None) , ( cell type: differentiated cells, None) , ( DNA: X-chromosome-specific elements, None)
