To investigate potential links between PANX1 and neurological conditions exhibiting dendritic spine pathology, we compared cellular localizations and biological functions of the synaptic PANX1 interactome with synaptic-enriched susceptibility genes for ASD, schizophrenia, Parkinson’s disease, and Alzheimer’s disease identified by GWASs. This evidence concerns the gene PANX1 and Parkinson disease.
