| Outline of Final Research Achievements |
We have enrolled total 54 participants including 15 ASD and their unaffected sibling (US) pairs and 12 healthy control sibling pairs in this study. When we compared gray matter volume (GMV) between ASD and US, there was no significant GMV difference between groups in a voxel-based analysis. However, when decreasing the level of significance, we found ASD had smaller GMV in the bilateral amygdala and caudate and larger GMV in the middle frontal gyrus compared to UN. These brain regions have consistently been reported to be associated with ASD pathology from previous meta-analysis studies. Although UN is not clinically diagnosed as ASD, UN has mild structure abnormalities in the brain regions related to the pathology of ASD. We suggested that these common findings between ASD and UN may be a specific biological marker for ASD.
