Do Adverse Drug Reactions Cause Autism Spectrum Disorder?

Adverse reactions to valproate drugs (anti-epileptics) during pregnancy enhance the expression of Rnf146 gene, which is known to cause autism spectrum disorder during fetal development. // These findings were interpreted in a multi-omnic study led by Professor Minsik Kim from the Department of New Biology at DGIST (President Kuk Yang), conducted along with the research teams led by Professor Yongsuk Lee at Seoul National University, Professor Junyong Ahn at Korea University, and Chanyeong Shin at Konkuk University.

All About Autism Spectrum Disorder

autism spectrum disorder is a neuro-developmental disorder that typically occurs in early childhood, in which behavioral patterns, interests, and activity range are restricted and repeated due to the inability to perform normal social communications and interactions (1^✔ ✔Trusted Source

Go to source). According to certain studies, 1 out of every 50 to 60 children has a spectrum disorder, making them fairly common.

Autism spectrum disorder is known to be caused by genetic factors as well as various environmental factors such as severe infection or exposure to specific types of drugs during pregnancy.

Is Autism Spectrum Disorder Catalyzed by Adverse Drug Reactions?

Meanwhile, a previous study conducted by the research team of Professor Chan-yeong Shin at Konkuk University discovered that valproate may be potentially related to autism spectrum disorder since it may affect the brain development of a fetus when used during pregnancy. However, the development of therapeutic drugs has faced challenges due to a lack of research on the molecular target.

Thus, the research team of Professor Minsik Kim performed a multi-omics analysis with Professor Ahn’s research team at Korea University using the mouse model treated with valproate developed by Professor Shin’s research team.

The results showed that expression of the Rnf146 gene, which is known to affect autism spectrum disorder, increased in the prefrontal lobe of the autism mouse model due to an adverse reaction to valproate.

Hidden Danger of Adverse Drug Reactions Linked to Autism Spectrum Disorder

Furthermore, autistic behavioral patterns were observed using the Rnf146 gene expression model in a joint effort with Professor Lee’s research team at the College of Medicine of Seoul National University. It was discovered that the balance between excitatory and inhibitory neurotransmitters was disturbed in the frontal lobe of the mouse model.

Professor Kim said, “We will continue our research on various developmental disorder models using multi-omics analysis through joint studies with other institutions and carry out comprehensive research on model organisms so as to identify the core network of autism spectrum disorder and discover treatment targets.”

Professor Shin of Konkuk University added, “The research results are expected to become the foundation of future research on the possibility of environmental pollution causing autism and the related mechanisms.”

Professor Ahn of Korea University stated, “In particular, the multi-omics technology is expected to be widely utilized in discovering a new molecular network in the brain development process and finding critical regulatory genes of various autistic models.”
