MRI studies of individuals with ZDHHC9‐associated ID identified neuroanatomical differences that may increase the risk for epilepsy and cognitive impairments, such as reductions in cortical thickness and connectomic deviations (Baker et al. 2015; Bathelt et al. 2016; Bathelt et al. 2017). The gene discussed is ZDHHC9; the disease is Cognitive impairment.
