The relationships between the topological properties of the whole-brain white matter network and the severity of autism spectrum disorder: A study from monozygotic twins

•Monozygotic ASD showed an abnormal topological properties of white matter network.•Monozygotic ASD had unique hubs distribution.•Global properties were associated with repetitive behavior.•Nodal efficiency of hubs was correlated with core symptoms of ASD.•Twin difference of network topological properties related to autism symptoms.
