MGI has improved its representation of the pseudoautosomal region (PAR)

  • A search for Chr XY with the Genes & Markers Query now returns all PAR markers, placed in the PAR by genome coordinates or by genetic mapping. PAR markers with genome coordinates can still be returned by coordinate searches of the corresponding chromosome (X or Y).
  • MGI now represents sequence-verified PARX / PARY homologous loci as distinct markers, with Chr X / Chr Y genome coordinates, respectively, and gene detail pages provide links to the Homologous PAR Feature. As an example, see the Erdr1x Gene Detail Page.
