Duplication of the entire 22.9 Mb human chromosome 21 syntenic region on mouse chromosome 16 causes cardiovascular and gastrointestinal abnormalities

Abstract excerpt

Down syndrome is caused by a genomic imbalance of human chromosome 21 which is mainly observed as trisomy 21. The regions on human chromosome 21 are syntenically conserved in three regions on mouse chromosomes 10, 16 and 17. Ts65Dn mice, the most widely used model for Down syndrome, are trisomic for approximately 56.5% of the human chromosome 21 syntenic region on mouse chromosome 16. To generate a more complete...
