Family association study of Transforming Growth Factor Beta1 gene polymorphisms in schizophrenia

Summary
Aim. Schizophrenia is a serious mental illness with chronic symptoms and significant impairment in psychosocial functioning. An etiopathological role for immunologic abnormalities in schizophrenia was hypothesized. Inflammatory markers are well-known etiological factors for psychiatric disorders, including schizophrenia. Several studies have investigated the possible effects of antipsychotics on inflammation and neurogenesis. Additionally, antiinflammatory adjuvant therapy has been under investigation as a treatment option for schizophrenia. Transforming Growth Factor Beta 1 (TGFB1) signaling is critical for many biological processes, including proliferation, development, differentiation and regeneration. Multiple members of the TGFB1 superfamily play a role in the developing nervous system and are regulated by neuronal activity. We conducted family-based study to assess whether TGFB1 gene is associated with susceptibility to schizophrenia in Polish population.
Methods. Two functional polymorphisms: rs1800469 (C-509T) and rs1800470 (T869C) of TGFB1 gene were analyzed within a group of 147 trios (patients diagnosed with schizophrenia and their healthy parents) using Transmission Disequilibrium Test (TDT).
Results. No association of these polymorphisms with schizophrenia was found in Polish population.
Conclusions. Further studies on larger groups along with correlation with circulating protein levels are needed.
