[ASD Related Information] Genetic Disorder and Autism Spectrum Disorder (ASD)
※ Genetic test
Nowadays, even minute changes in DNA can be found through a new genetic test called CHROMOSOME MICROARRAY ANALYSIS. With the development of technology, much more sensitive testing methods such as WOLE EXO-SEQUENCING can be combined with chromosome microarray testing to find out the entire sequence of DNA molecules that produce proteins on chromosomes. These tests provide a better understanding of how changes in DNA cause ASD. As the new precision testing method is expensive, it is very important that insurance coverage is applied.
※ Benefits and Limitations of Genetic Testing
1. advantages
Relatively accurate causes of ASD can be identified.
You can tell if the family is in a visible state.
More accurate genetic counseling is possible when trying to have children in the future.
Decisions can be made based on abundant and accurate information about having children, including artificial insemination.
The need for many diagnostic tests to find the cause of ASD is relatively small.
Although there may be no treatment, genetic diagnosis can detect comorbidities and minimize the impact of complications commonly associated with certain genetic diseases.
Once a definite genetic diagnosis has been made, participation in research can expand knowledge of the disorder, and if a treatment is developed, it can be tried first.
They can help each other by communicating with all families around the world who have registered in a specific genetic disease group and have been diagnosed with the same diagnosis.
2. the limit
In most cases, the underlying cause is unknown.
The cost of testing is high, and insurance benefits may not apply.
Even if a definite diagnosis is made, the treatment method may not change significantly.
If we do not know exactly about the mutation or replication number variation (deletion or duplication of DNA), the results may be ambiguous.
