A few days ago, a strange research came to light that Y chromosomes are disappearing in men. Which is a matter of concern. Now another research has come out that extra Y chromosome has been found in men. This serious disease increases the risk of autism. Research has also revealed that due to extra Y, the risk of autism is increasing significantly in men.
Chromosomes determine biological gender.
Sex chromosomes determine the biological gender of a person. Men usually have XY chromosomes in their cells. Whereas women have XX chromosomes. However, some individuals have an abnormal number of X or Y chromosomes, such as XXY or XYY. Which is a genetic condition known as ‘sex chromosome aneuploidy’. Autism is a neuro-developmental condition. In which the person displays repetitive behavior and social skills are affected. According to the study, it has been found to be almost four times more common in men than in women. Which shows a strong gender aspect in this skewed ratio.
Institute for Autism and Developmental Medicine. Scientists, including those in the US, looked at the diagnosis of autism in people with abnormal sex chromosomes and found that those who had an extra Y chromosome were XYY or XXY. They were twice as likely to be diagnosed with autism. According to researchers, having an extra
1 lakh 77 thousand people were included in this research.
The team analyzed genetic and autism diagnosis data on 1,77,416 patients. Of which 350 had abnormal sex chromosomes. Additionally, having an XYY chromosome was found to have a higher risk of autism than having an XXY. The findings of the study were recently published in the journal Nature Communications. The authors said that the study results suggested a risk factor associated with the Y chromosome, which is in contrast to the protective effect associated with the X chromosome.
According to a major theory in the research field called ‘female protective effect’. The protection provided by the The authors said the study’s findings pointed to the need to look for autism risk factors on the Y chromosome.
Instead of limiting itself to the protection provided by the X chromosome. They called for further research to identify specific autism risk factors linked to the Y chromosome. The Simons Foundation was involved in the Powering Autism Research (SPARC) study and the MyCode Community Health Initiative, both in the US.
