Although CYP2G1P and STOML3 have not been directly implicated in postpartum psychiatric phenotypes, altered mechanosensory processes may contribute towards depression susceptibility (Howard et al. 2018), and the genomic region around STOML3 has been associated with autism spectrum disorders, psychotic depression, and schizophrenia risk (Domschke 2013; Li et al. 2016; Roberson-Nay et al. 2018; Bitar et al. 2019). This evidence concerns the gene STOML3 and schizophrenia.
