Finally, in a study focusing on the network of miRNA sponges for various neuropsychiatric disorders, including autism, HAR1A was identified as a candidate for this role in the autism spectrum disorder (Balasubramanian and Vinod, 2022) and was also found to be downregulated in AD (Li and De Muynck, 2021). The gene discussed is HAR1A; the disease is autism spectrum disorder.
