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, ...

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 ...

Down syndrome is caused by an extra copy of chromosome 21. Because of genes present on this chromosome that are known to ...

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 ...

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 ...

People with a third copy of chromosome 21, known as trisomy 21, are at high risk of developing acute myeloid leukemia (AML), an aggressive form of blood cancer. Scientists have now identified the ...

People with a third copy of chromosome 21, known as trisomy 21, are at high risk of developing Acute Myeloid Leukaemia (AML), an aggressive form of blood cancer. Scientists led by the Department of ...

Down syndrome is a condition in which a person has a fully or partially duplicated copy of chromosome 21. (A chromosome is a structure made up of DNA and proteins found in the nucleus of each cell.) ...
