Marijuana may damage oocytes — unfertilized eggs in female ovaries — in ways researchers worry may lead to infertility, miscarriage and possible genetic defects in babies, new research has found.

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, ...

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 ...
