Autism Is Often Caused by Defects in Certain Genes
Research scientists have made public their announcement that they have found a gene abnormality that is related with one percent of all instances of autism. According to the findings of other knowledgeable individuals, this particular area of the genome is connected to an increased prevalence of autism cases.
The researchers believe that by locating this genetic flaw, they will be able to improve the accuracy of early disease diagnosis and possibly even mitigate the negative effects of the condition on childhood development.
Dr. Mark Daly of Massachusetts General Hospital served as the study's primary investigator. He made the point that genetic testing can assist parents in determining whether or not the identified child's siblings are also at risk for the disease and whether or not subsequent children would have the condition.
Autism encompasses a spectrum of illnesses, ranging from Asperger's syndrome in its mildest form to autism severe enough to cause intellectual disability and a loss of social skills. This disorder affects one in every 150 children in the United States, which translates to a total of 1.5 million children and adults who are afflicted with it.
During a telephone interview, Dr. Daly stated that "Early prevention, such as behavioral and educational therapies, can help autistic children recover and can also help detect symptoms before formal diagnosis."
The findings of the study were presented in a report that was printed in the New England Journal of Medicine. In a comment that they published in the publication, Dr. Evan Eichler of the University of Washington Seattle Branch and Andrew Zimmerman of Johns Hopkins University stated that the detection of these genetic problems "may only be the tip of the iceberg."
Heterogeneous genetic code
According to Ashley and Zimmermann, until this day, a total of 150 genomic areas that are prone to 'heterogeneity' have been found.
The authors state in their paper that "it is obvious that the treatment approaches for patients with various symptoms of autism are neither straightforward nor uniform."
Ashley's coworkers and the team conducting research on the autism gene discovered that out of 2,252 people in the United States and Iceland with a family history of autism, 24 had deletions or duplications of chromosome 16, but only two such abnormalities occurred among a randomly selected group of 18,000 people.
Previous studies have established a connection between autism and identical duplications on chromosome 15, which are responsible for an extra 1–2% of cases.
According to the findings of numerous studies, the majority of genetic alterations are not inherited. There are two different ways in which the mutations can take place: first, they might emerge naturally within an individual, as is the case with cancer; second, they can be inherited from one's parents.
The etiology of autism is still a mystery, and the topic of widespread discussion in the field continues to this day.
