Autism (ASD) is often interpreted as a condition with a strong genetic component, but multiple studies suggest that there are also non-genetic heritable factors that contribute to risk.<\/p>\n\n\n\n
A recent study published by Dr. Richard E. Frye and colleagues<\/a> They explore how folate receptor alpha autoantibodies (FRAAs) might act in parents and their children, disrupting folate transport to the brain and increasing the risk of ASD.<\/p>\n\n\n\n This study suggests that folate may not normally reach the central nervous system when these antibodies are present, affecting processes such as methylation, neurotransmitter production, and DNA repair, among others.<\/p>\n\n\n\n This design allows for comparing not only those affected (ASD) with controls, but also for analyzing how these antibodies act within families.<\/p>\n\n\n\n Families with multiple children with ASD (multiplex) had significantly higher levels of blocking FRAAs than families with one child with ASD (simplex). This suggests that in families with more cases of ASD, these autoantibodies may accumulate or have a more intense effect.<\/p>\n\n\n\n Levels of blocking FRAAs tended to increase with parental age. Furthermore, multiple pregnancies (twins) showed higher levels, suggesting an interaction with gestational factors that could exacerbate the production of these antibodies.<\/p>\n\n\n\n A significant correlation was identified between the levels of blocking FRAAs in mothers and their children, raising the possibility that these antibodies may be transmitted or intensified generationally, a phenomenon known as "anticipation" in non-classical genetics.<\/p>\n\n\n\n Fathers with positive FRAAs tended to have children with more severe ASD symptoms and poorer cognitive and behavioral development. This suggests that the presence of paternal autoantibodies is not innocuous, but may directly influence the clinical profile of the disorder.<\/p>\n\n\n\n Both children with ASD and their families (siblings, parents) showed higher levels of ARF compared to controls without a history of ASD. This difference supports the hypothesis that ARF represents a hereditary risk factor, not a purely genetic one.<\/p>\n\n\n\n These findings position FRAAs as a non-genetic heritable factor: that is, they can contribute to ASD risk without relying solely on DNA mutations. By accumulating or intensifying generation after generation, they could act as a type of progressive immunological burden.<\/p>\n\n\n\n The fact that levels increase in successive generations suggests that we not only inherit the genetic component of autism, but also possible immunological disorders that may increase over time in certain families.<\/p>\n\n\n\n Detecting these antibodies in couples before pregnancy could offer a window of opportunity to modulate risk. If both parents are identified as positive, medically supervised folinic acid supplementation could be considered to reduce the impact of these antibodies on fetal development.<\/p>\n\n\n\n The effect of FRAAs may depend on each individual's metabolic, nutritional, and immunological environment. Not everyone with these antibodies develops ASD, suggesting that other factors such as nutrition, oxidative stress, microbiota, and genetics also play a role.<\/p>\n\n\n\n To evaluate the presence of these autoantibodies the test is used FRAT\u00ae<\/a> (Folate Receptor Autoantibody Test), a blood test that detects both blocking and binding FRAAs.<\/p>\n\n\n\n This test confirms whether folate transport to the brain may be altered by immune action. Ideally, it should be performed before pregnancy or in the early stages of pregnancy in couples with a history of ASD.<\/p>\n\n\n\n A positive result would allow for consideration of supplementation strategies (folinic acid) and closer monitoring, always with the help of a medical professional.<\/p>\n\n\n\n In the context of Dr. Frye's study, the use of FRAT testing could be essential for identifying which families are at greater immunological risk, beyond traditional genetic risk.<\/p>\n\n\n\n These recommendations do not guarantee absolute prevention, but represent a strategy based on the findings of this scientific study.<\/p>\n\n\n\n At Enevia, we want to emphasize the importance of preventing the risks associated with developing autism and promote science-based tools that can help. <\/p>\n\n\n\n If you have any questions or need a professional to advise you, you can schedule a Consult with our specialists at Enevia Care<\/a>.<\/p>\n\n\n\n Because at Enevia, we are your health ally.<\/p>\n\n\n\n Here's another article from our blog about brain folate deficiency (CFD): <\/p>\n\n\n\n![\"Metabolismo](\"https:\/\/test.eneviahealth.com\/wp-content\/uploads\/2025\/09\/Metabolismo-del-folato-1024x950.png\")
