By means of cross-reacting molecular probes, some 18 loci specific for the X chromosome of both man and mouse have been localized on the mouse X chromosome using an interspecific mouse cross involving the inbred SPE/Pas strain derived from Mus spretus. Comparison of the localizations of these loci on the mouse X with their positions on the human X chromosome suggests that intrachromosomal rearrangements involving at least five X chromosome breakage events must have occurred during the period of evolutionary divergence separating primates from rodents. Within the five blocks of chromosomal material so defined, there is for the moment little or no evidence that either chromosomal inversion events or extensive rearrangements have occurred. These data confirm the remarkable evolutionary conservation of the X chromosome apparent in mammalian species, compared to autosomal synteny groups in which both inter- and intrachromosomal rearrangement events appear to have occurred frequently. The breakage events described here for the X chromosome should therefore provide a minimal estimate for the frequency of chromosomal rearrangement events, such as breakage and inversion, which have affected autosomal synteny groups during the evolutionary period separating man from mouse. The definition of the number of chromosome breakage events by which the X chromosomes of these species differ, together with their localization, provides a framework for the use of interspecies mouse crosses for further detailed mapping of particular subchromosomal regions of the human X chromosome and for defining loci in the mouse homologous to those implicated in human congenital diseases.
