Telomere Length in ASD
Exploring the relationship between telomere and autism, it is vital to understand the impact of telomere length within the context of Autism Spectrum Disorder (ASD). Studies have shed light on the association between shortened telomeres and ASD diagnosis, particularly within families affected by the condition.
Shortened Telomeres in ASD Families
Research has shown that families of children with ASD exhibit shortened telomeres in comparison to families with no history of ASD. This difference is noticeable at the individual family member level, with infants, probands, and mothers in high-risk ASD families displaying reduced relative telomere length when compared to low-risk ASD families. Although less pronounced, fathers of high-risk infants also demonstrate a similar trend of decreased telomere length.
Telomere Length in Children with ASD
In a comparative analysis, children and adolescents diagnosed with autism spectrum disorder (ASD) were found to have shorter telomere length when contrasted with typically developing individuals. Interestingly, unaffected siblings of children with ASD exhibited telomere length falling between those of typically developing individuals and ASD-affected individuals. This insight suggests a potential genetic component associated with telomere length and ASD susceptibility.
Furthermore, studies emphasize the importance of telomere length and oxidative stress markers in relation to ASD. Shortened telomere length, together with reduced catalase (CAT) activity, has been identified as risk factors for ASD development. Conversely, reduced 8-hydroxy-2-deoxyguanosine (8-OHdG) content and superoxide dismutase (SOD) activity appear to act as protective factors against ASD onset [3].
This compelling evidence underlines the significance of telomere length in the context of ASD and suggests a potential biomarker for understanding the genetic and environmental influences contributing to the development and severity of symptoms associated with this neurodevelopmental disorder. By delving deeper into the intricate relationship between telomeres and ASD, researchers aim to uncover novel insights into the underlying mechanisms of this complex condition.
