The unveiling of the DNA sequences of human chromosomes represents a new chapter in the unfolding story of genomics, but one with roots in the half-century-old field of cytogenetics. Chromosome-level ...

Conservation of genomic sequences between species indicates regions of functional importance, containing protein-coding gene, non-coding genes or regulatory elements. In the December 5 Nature, ...

How does the CRISPR Down Syndrome breakthrough work to remove the extra chromosome 21? We are closer than ever to a world where a genetic condition affecting one in every 700 babies could be addressed ...

Decades ago, researchers showed that Down syndrome (also known as trisomy 21), was caused when individuals carried an extra copy of chromosome 21. Down syndrome is also the most common genetic cause ...

Three copies of chromosome 21 causes Down syndrome (DS), and roughly half of children born each year in the United States with DS-approximately 2,600-also have congenital heart defects (CHDs). What is ...

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 Mie ...

Sanjeev S. Ranade, PhD, is an assistant professor in the Center for Cardiovascular and Muscular Diseases and Center for Data Science and Artificial Intelligence at Sanford Burnham Prebys. Three copies ...

Scientists first read the human genome, a three-billion-letter biological book, in April 2003. Since then, researchers have steadily advanced the ability to write DNA, moving far beyond single-gene ...
