Subnetworks 26 and 34 suggested the association between PCOS and schizophrenia with the identification/existence of four PCOSrps (HLA-A (HLA class I histocompatibility antigen, A-2 alpha chain), HLA-C (HLA class I histocompatibility antigen, Cw-12 alpha chain), HLA-E (HLA class I histocompatibility antigen, alpha chain E), and LILRB1 (leukocyte immunoglobulin-like receptor subfamily B member 1)) in subnetwork 26 and 27 PCOSrps in subnetwork 34. Here, HLA-A is linked to polycystic ovary syndrome.
