title: New insights into the man-mouse comparative map of the X chromosome.
abstract: Two conserved loci, DXHX674h and DXHX679h, which map to Xp11.22-Xp11.21 on the human X chromosome short arm, have been positioned between the loci for proteolipid protein (Plp) and the E1a subunit of pyruvate dehydrogenase (Pdha1) in the distal region of the mouse X chromosome using Mus musculus x Mus spretus interspecific backcrosses. These data, together with previous comparative mapping studies on another conserved locus (DXF34) and the locus that encodes the erythroid transcription factor (GATA1), reveal that loci that map to the proximal region of the human X chromosome short arm lie in four different regions of the mouse X chromosome and that the human and mouse X chromosomes contain a minimum of eight conserved segments.
