Localization of four human chromosome 21 genes--SOD1, ETS2, IFNAR, and CBR--to two different chromosomes in the marsupial species Macropus eugenii.

We have mapped the chromosomal location of four genes previously assigned to human chromosome 21—Cu/Zn superoxide dismutase (SOD1), the protooncogene ETS2, the interferon α/β receptor gene (IFNAR), an
