Researchers have uncovered a serious risk for folks who have an extra X or Y chromosome. Those with the genetic condition known as supernumerary sex chromosome aneuploidy have a risk for blood clots ...

A comprehensive genetic analysis of over 200,000 men has found that around one in 500 have an extra sex chromosome, with most of them unaware. That’s a much higher proportion than previously thought, ...

A study on the extra chromosomes titled "Detection and characterization of male sex chromosome abnormalities in the UK Biobank study" has been published in the journal Genetics in Medicine. Data from ...

Yale scientists have discovered a new potential treatment avenue to fight cancer. Using CRISPR gene-editing, the team eliminated extra chromosomes from cancer cells and found that they could no longer ...

B chromosomes, often termed supernumerary chromosomes, represent non-essential additions to the standard (A) chromosome set in many eukaryotes. Despite being dispensable, they offer a unique window ...

Around one in 500 men could be carrying an extra X or Y chromosome—most of them unaware—putting them at increased risk of diseases such as type 2 diabetes, atherosclerosis and thrombosis, say ...

Humans carry 46 chromosomes. We get one from each parent, making 22 pairs of autosomal chromosomes, and one pair of sex chromosomes. Women usually carry two X (sex) chromosomes, while men typically ...

Most chromosomes have been around for millions of years. Now, researchers from the Stowers Institute for Medical Research have revealed the dynamics of a new, very young chromosome in fruit flies that ...

Extra X chromosomes significantly increase the risk for systemic lupus erythematosus (SLE) and Sjögren disease, with the prevalence of these conditions being higher among patients with Klinefelter and ...

For Ashley Zambelli, a surprise diagnosis allowed her to have an even more special bond with her children. The Michigan-based mom, 23, recently found out she has Mosaic Down syndrome, a condition in ...

Scientists have long known that cancer cells typically have extra chromosomes, but what exactly was the extra genetic material doing? New research from a team at Yale University has finally provided ...

Most chromosomes have been around for millions of years. Now, researchers have revealed the dynamics of a new, very young chromosome in fruit flies that is similar to chromosomes that arise in humans ...
