“Loci Associated with Neonatal C3 and C4 Protein Concentrations and Their Link to Schizophrenia and Autoimmune Disorders”

https://pubmed.ncbi.nlm.nih.gov/38116117

This study identifies loci associated with neonatal C3 and C4 protein concentrations and finds that a higher C3 concentration in females is associated with a reduced risk of schizophrenia, and C4 is linked to altered risk in five autoimmune disorders.
