researchers from Cold Spring Harbor Laboratory (CSHL) challenge the conventional understanding of the genetics of ASD. Autism (TEA). Contrary to the prevailing idea that siblings with ASD share more of the maternal genome, associate professor Ivan Iossifov and CSHL Professor Michael Wigler revealed that, in many cases, it is the father who plays a more important genetic role. significant.
This finding flips the previously established script on its head and offers a new perspective on genetic influences on the development of ASD, which is something of a surprise.

Autism Spectrum Disorder (ASD)
You Autism Spectrum Disorders (ASD) encompass a wide range of neurological and developmental conditions that can impact many aspects of a person's life. There may be some difficulty in communication, social interaction, learning and behavior.
Symptoms such as repetitive behaviors and restricted interests are also common. In the United States, it is estimated that about one in every 36 children is affected by ASD.
This condition requires adequate understanding and support to promote the well-being and healthy development of people with ASD.
Over the past twenty years, scientists from the Cold Spring Harbor Laboratory (CSHL) have been leading a comprehensive effort to unravel the genetic origins of autism. During that time, they identified thousands of genes that, when mutated, can contribute to the development of Autism Spectrum Disorder (ASD) in children.
Researchers discover important part of genetic makeup and role of parents
Despite these significant findings, there are still cases of ASD that cannot be explained by the variants. geneticalready known.
Determined to find these "lost sources", researchers Ivan Iossifov and Michael Wigler embarked on a new investigation to unravel the additional genetic causes of ASD. In the study, they examined the genomes of more than 6,000 families who had volunteered to participate in the research.
Surprisingly, they observed an interesting pattern in families with two or more children diagnosed with ASD: siblings shared a greater proportion of the father's genome than expected.
However, in families where only one of the children had ASD, the father's genome share was smaller.
This discovery not only reveals a potential new source of genetic influence in ASD, it also raises the intriguing question of whether other disorders might follow the same genetic rules.
Additionally, the research paves the way for future investigations into the genetic origins of a variety of neurological conditions and development, as well as leading to more accurate early diagnoses and a deeper understanding of autism as a whole.
With a clearer understanding of the genetic underpinnings of autism, professionals in education and therapycan adapt their methods and strategies to meet the individual needs of people with ASD, providing more effective and targeted support.
