ZDHHC20 and schizophrenia: 2016). We identify cg18095732 as a methylation site regulating ZDHHC20 expression, providing a mechanistic link between epigenetics and palmitoylation in schizophrenia. This finding echoes genome‐wide methylation studies showing altered patterns in the brains and peripheral tissues of schizophrenia patients, impacting genes tied to synaptic plasticity and inflammation (Starnawska and Demontis 2021).
