ERVW-1 and schizophrenia: Recent transcriptome-wide association studies (TWAS) integrating HERVs expression data revealed 13 HERV loci significantly associated with schizophrenia risk (P<5×10-8), with HERV-W and HERV-K transcripts upregulated in glutamatergic neurons, linking HERV activity to genetic risk and neurodevelopmental dysregulation (Duarte et al., 2024).
