Researchers from Denmark, USA, and Finland have identified a variation in the gene that causes autism. According to their research, there is a common genetic variation which increases the risk of getting autism. The study reveals that genetic variation in five specific genes is directly involved in increasing the risk of autism. There are a few biological processes involved in the development of autism. These genes activate biological processes.
Autism can be potentially curable according to research
Autism is a neurological disorder in which the cells in the brain and central nervous system get affected. It is a rare disease affecting around 1% of the total population. It is hereditary. Genes play an essential role in this disease.
According to the study, the five specific genes directly involved in increasing the risk of the disease are involved in brain development. The symptoms of autism are related to functions that are disturbed because of dysfunction in the cerebral cortex.
This research was a successful cohort based study conducted on 190,000 people. These constituted 20,000 autistic patients and 170,000 normal individuals.
Scientists studied the genomes of these individuals and identified the specific genes responsible for creating the link for the disease.
Researchers hope that in future they will be able to filter more precise diagnosis for autism. This means that they will be able to separate the precise genes from the less precise ones to get a more thorough understanding of the disease. This clarity will provide us with more information to identify the root cause. This will ultimately pave the way for the efficient treatment of the disease.
Researchers from Denmark iPSYCH research project, University of Aarhus and Broad Institute from the USA conducted this study and got it published in the scientific journal called Nature Genetics.
Scientists from all over the world have been trying to identify the specific link between autism and genetics for decades. Finally, it is possible to see the underlying cause. Director of the Institute of Molecular Medicine Finland FIMM, professor Mark Daly from the University of Helsinki is one of the leading scientists involved in the research. He stated that hereditary factors have 80% role in this disease. However, we were not able to point out the exact genes involved in it. This study will further help us to find a potential cure for autism.
According to this research, seven more genetic variants are found responsible for the occurrence of other mental disorders.
The genomic study will help us identify other mental disorders in the future as well.
