| Research Abstract |
Mitochondrial dysfunction (MtD) has been observed in approximately five percent of children with autism spectrum disorders (ASD). MtD could impair highly energy-dependent processes such as neurodevelopment, thereby contributing to autism. In this study, we carried out detailed analyses involving gene expression and genetic association studies of genes related to diverse mitochondrial functions. As a result, several genes showed brain region-specific expression alterations in subjects with autism compared to controls. MTX2, NEFL and SLC25A27 showed consistently reduced expression in the anterior cingulate gyrus, motor cortex and thalamus of autism subjects. NEFL and SLC25A27 showed genetic association with autism in Caucasian and Japanese samples, respectively. The expression of DNAJC19, DNM1L, LRPPRC, SLC25A12, SLC25A14, SLC25A24 and TOMM20 were reduced in at least two of the brain regions of autism patients. Our study brings to light new genes associated with MtD in autism.
