Scientists in Japan have used gene-editing technology to remove the extra chromosome responsible for Down syndrome, at least in lab-grown human cells. The project, led by Dr. Ryotaro Hashizume of ...

Researchers at the Francis Crick Institute and UCL have identified a gene that causes heart defects in Down syndrome, a condition that results from an additional copy of chromosome 21.

The sequence of chromosome 21 was a turning point for the understanding of Down syndrome. Comparative genomics is beginning to identify the functional components of the chromosome and that in turn ...

Now, scientists from the Francis Crick Institute and University College London have linked Dyrk1a, a gene on human chromosome 21, to heart defects in these individuals that could open a door to ...

Down Syndrome is a genetic condition in which a person is born with an extra copy of chromosome 21, according to the Cleveland Clinic. Whereas people are usually born with 46 chromosomes, those ...
