In various regions of autism brains, we observed alterations in the expression of several genes related to mitochondrial transport, such as, AIP, BCL2, DNAJC19, HSP90AA1, MFN2, MIPEP, TP53 and TSPO. The expression of DNAJC19 was downregulated in the MC and THL of autism patients. This evidence concerns the gene HSP90AA1 and autism.
