Genetic
testing for autism is recommended as autism is very common among children now a
day. Autism is a crippling disease and it affects the child’s learning ability.
Genetic testing will help in determining the causative factors for autism early
in life and hence a proper treatment plan can then be devised. Read on to know
more.
Autism is now found to be common amongst children
and this perhaps because of the higher awareness levels. However, there is
scope for greater progress in the treatment of the disease. Researchers have
continued to be eluded to find the exact root cause of the disease and
determine a perfect potential cure.
The treatment is still in the research level as most
of the options tried out are experimental in nature. In order to demystify
autism it is important to have all the relevant information under a single head
and in the right order so that the picture has all the missing links together
in order to decode it. This calls for genetic
testing as it holds the key to a world of information that actually needs
to located and identified in the correct manner.
Now
What is Autism?
It is a puzzling disorder. It is directly related to
developmental disorders or delays and the signs for the disease are recognized
when the child shows reluctance or inability to meet the developmental
milestones as he grows up.
Significance
of Genetic Test for Autism
Genetic tests for autism
are suggested due to the following main reasons.
- Autism is found to be a very prevalent disorder today. Researchers are doctors are baffled that if this be a trend then there must a definite cause behind it that needs to be identified.
- Since autism is a serious disorder as it cripples the child’s ability to learn for a lifetime (in most cases), the condition needs to be detected as early as possible.
- Genetic testing for autism will pave the way for an effective treatment so that the child’s suffering is minimized. This is only possible if the information is received early, and genetic test is the way out.
How
is the Screening for Genetic Test for Autism Conducted?
When the child is in the developmental stage, the
parents and teachers are in the best position to observe whether the child is
showing signs of developmental delays. This is when the baby is not attaining
the developmental milestones within the expected time or not attaining at all.
The moment they notice this deficiency, they must
understand that the child needs to be screened for autism. This is basically
the first level of screening. In the second level a formal evaluation is
conducted which comprises of the diagnosis and procedure of treatment suggested
by the doctor. Here a medical geneticist is the perfect person to conclude
whether the specific genetic traits leading to autism is present in the child
or not.
Types
of Genetic Testing for Autism
Genetic test for autism is of three types.
G-Banded
Karyotype Testing – Karyotyping
is a standard genetic test that is a part of the child’s regular health
screening. Any abnormality in the genetic pattern can be identified through
this test. It has been noticed that any presence of abnormalities can be
detected in 2% of the patients through this test.
Fragile
X Testing – This test is likely to reveal any possible abnormality
in 0.5% of the children.
CMA
– This is a new test option that is conducted in the molecular level. Compared
to the above two variants the results of this test is found to be more
effective as the abnormalities were detected in 18% of the children tested. The
usual or known genetic disorders were found in 7% amongst the 18% segment. This
proves it effectiveness in determining and detecting abnormalities.
Benefits
of Genetic Testing
In order to detect the genetic disorders leading
to autism, these genetic tests particularly the CMA can in turn lead to early
intervention and treatment. This can effectively control the autistic condition
and help the child and his family lead a better life. Further these genetic
tests for autism also inform the parents whether there is a likelihood of their
future children carrying the same disorder.
