摘要

All of the mouse models of human trisomy 21 syndrome that have been studied so far are based on segmental trisomies, encompassing, to a varying extent, distalchromosome 16. Their comparison with one or more unrelated and non-overlappingsegmental trisomies may help to distinguish the effects of specific triplicated genesfrom the phenotypes caused by less specific developmental instability mechanisms. Inthis paper, the Ts43H segmental trisomy of mouse chromosome 17 is presented as suchan alternative model. The trisomy stretches over 32.5 Mb of proximal chromosome17 and includes 486 genes. The triplicated interval carries seven blocks of syntenywith five human chromosomes. The block syntenic to human chromosome 21 contains20 genes.
