Sex chromosome abnormalities (SCAs), also known as X or Y chromosome abnormalities, can lead to dysplasia of sexual organs in both males and females 1. SCAs are relatively common, with an estimated ...

Researchers have identified a gene that causes heart defects in Down syndrome, a condition that results from an additional copy of chromosome 21. Reducing the overactivity of this gene partially ...

Large and rare duplications and deletions in a chromosome region known as 22q11.2 , which involves genes that regulate cardiac development, are linked to nonsyndromic bicuspid aortic valve disease, ...

(Cavan Images/Getty Images) The human Y chromosome is shrinking. In the next 5 million years or so, some geneticists think the sex-determining chromosome will vanish completely from our species. In ...

The CRISPR tool is capable of repairing the genetic defect responsible for the immune disease chronic granulomatous disease. However, researchers at the University of Zurich have now shown that there ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...
