Men losing Y chromosomes as they age may face a higher risk of heart disease, cancer, and reduced life expectancy. Here’s ...

Conventional investigations of the genetic contributors to Alzheimer's disease (AD) risk and progression have ignored the role of the X-chromosome, primarily due to technical analysis limitations. To ...

In female mammals, one of the two X chromosomes is usually inactive and forms the so-called Barr body. The image shows a cell nucleus with the Barr body marked in green. Unlike men, who carry one X ...

As millions of ageing men lose the Y chromosome, evidence links this silent shift to heart disease, cancer and shorter lives – what’s at stake?

Affected populations: This genetic, multisystem disorder affects an estimated 1 in 30,000 to 1 in 10,000 people worldwide. Most cases of the syndrome occur sporadically, meaning the genetic changes ...

Gene editing techniques may eventually allow trisomy to be treated at the cellular level, according to an in vitro proof-of-concept study. Down syndrome is caused by the presence of a third copy of ...

Boys are three times more likely to be diagnosed with autism than girls, research suggests, and scientists found a link that may shine a light on why. According to new research from the Geisinger ...

New @hopkinskimmel research finds extra copies of chromosome 1q may drive the earliest stages of pancreatic cancer. › ...

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.

Genes are segments of DNA (deoxyribonucleic acid) that are located inside every human cell. The DNA inside each cell is tightly coiled in structures called chromosomes. Each chromosome contains a ...
