Scientists achieved a genetic breakthrough by removing an extra human chromosome using gene-editing technology. This landmark study successfully deleted the surplus chromosome 21 responsible for Down ...

Around 1 in 500 men carry an extra X or Y chromosome, according to a large study published this week in Genetics in Medicine. But most of those affected are unaware of their status, despite it ...

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 ...

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 ...

In today’s study, the researchers identified 213 men with an extra X chromosome and 143 men with an extra Y chromosome. As the participants in UK Biobank tend to be ‘healthier’ than the general ...

Scientists silenced the extra copy of a chromosome that causes Down syndrome in laboratory stem cells, offering the first evidence that it may be possible to correct the genes responsible for the ...

It is common knowledge that Down syndrome—a neurodevelopmental and neurodegenerative disorder with hallmark physical features and mild to moderate cognitive impairment—occurs when individuals have an ...

In pursuit of better ways to test new therapies and further explore the impacts of the unique genetics associated with Down syndrome, researchers at Johns Hopkins Medicine and Tottori University in ...

A microscopic piece of genetic material known as the Y chromosome made headlines last week. It is nothing new or rare; every man has one in practically every cell, or he would not be a man. But a few ...

A baby’s genetic makeup is determined when the sperm meets the egg during fertilization. Typically, a full set of DNA is formed, which contains 23 pairs of chromosomes. Sometimes, extra chromosomes ...
