The research is a transformative step toward understanding the condition's genetic underpinnings and potential for ...

Researchers have uncovered four distinct types of autism, each with its own genetic fingerprint, which could unlock the ...

The Y chromosome is about one-third the size of the X and contains far fewer genes. Now, scientists have found that this smaller chromosome can degrade over time. "The idea is that as men grow ...

The Y chromosome can disappear over time in human males, which may introduce a number of health problems. While the exact trigger for such degeneration is unknown, environmental factors can play a ...

Historically, the Y chromosome has been misunderstood. For a long time, it wasn't thought to be essential in adults, and some even hypothesized that it was going to disappear altogether.

Additional Genetic Insights At the same location on the X chromosome, the researchers found evidence that another gene, PTCHD1-AS, might be involved in autism. The study highlights a case where a boy ...

The human Y did once contain as many genes as the X chromosome, but has lost them in the past 166 million years. As a result, most of the Y today is made up of repetitive "junk DNA." ...

DANVILLE — Increased risk for autism appears to be linked to the Y chromosome, a Geisinger study found, offering a new explanation for the greater prevalence of autism in males. The results were ...

"While these may seem like two sides of the same coin, our results encourage us to look for autism risk factors on the Y chromosome instead of limiting our search to protective factors on the X ...

Photo of two children drawing together. Autism diagnoses are three times more common in boys than girls, and it may come down to the Y chromosome. SeventyFour/Getty To test this, the team analyzed ...

Researchers, including those from the Autism and Developmental Medicine Institute, US, looked at autism diagnoses in people having abnormal sex chromosomes and found that those having an extra Y ...
