Abstract		This study investigated the associations between single nucleotide polymorphisms in the neurodevelopmental Disrupted In Schizophrenia 1 ( DISC1 ), neuregulin 1 ( NRG1 ), brain-derived neurotrophic factor ( BDNF )and NOTCH4 genes and the clinical symptoms and the occur- rence of treatment-resistant schizophrenia in the Slovenian population. We included 138 schizophrenia patients, divid- ed into treatment-responsive a nd treatment-resistant group and 94 healthy blood donors. All subjects were genotyped for eight polymorphisms ( DISC1 rs6675281, DISC1 rs821616, NRG1 rs3735781, NRG1 rs3735782, NRG1 rs10503929, NRG1 rs3924999, BDNF rs6265, NOTCH rs367398) and investigated for associations with clinical variables. NOTCH4 rs367398 AA/AG was significantly associated with worse Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impression (CGI) score. NOTCH4 rs367398 was not statistically significant- ly associated with the occurrence of treatment-resistant schizophrenia after the correction for multiple testing. Our data indicate that NOTCH4 polymorphism can influ- ence clinical symptoms in Slovenian patients with schizophrenia
