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; DNA: inactive X chromosome; DNA: Xi; cell type: differentiated cells; DNA: X-chromosome-specific elements
