Additionally, although lower FAK in multi‐fiber WM regions has been reported in autism (He et al. 2023), suggesting reduced microstructural anisotropy and potentially less organized or less directionally complex tissue, higher FAK was also observed in both multi‐fiber tracts (e.g., fornix, corpus callosum; Shen et al. 2024) and GM regions (e.g., frontal lobe, hippocampus; Tang et al. 2022). Here, PTK2 is linked to autism.
