Trisomy-21 gene dosage over-expression of miRNAs results in the haploinsufficiency of specific target proteins.

Down syndrome (DS) or Trisomy 21 (Ts21) is caused by the presence of an extra copy of all or part of human chromosome 21 (Hsa21) and is the most frequent survivable congenital chromosomal abnormality. Bioinformatic annotation has established that Hsa21 harbors more than 400 genes, including five mic... View More
