GARCIA VALENCIA, Jenny et al. Association of schizophrenia and its clinical implications with the NOS1AP Gene in the Colombian population. rev.colomb.psiquiatr. [online]. 2012, vol.41, n.2, pp.249-272. ISSN 0034-7450.

Introduction: The nitric oxide synthase 1 adaptor protein (NOS1AP) gene is possibly implicated in schizophrenia etiopathogenesis. Objective: To determine the association of NOS1AP gene variants with schizophrenia and the relationship of variants with the clinical dimensions of the disorder in the Colombian population. Methodology: It is a case-control study with 255 subjects per group. Markers within the NOS1AP gene were typified as well as other informative material of genetic origin so as to adjust by population stratification. A factorial analysis of the main components for each item in the Scales for Evaluating Negative Symptoms (SENS) together with the Scales for Evaluating Positive Symptoms (SEPS) to determine clinical dimensions. Results: Association between the C/C genotype of the rs945713 marker with schizophrenia (OR = 1.79, 95% CI: 1.13 - 2.84) was found. The C/C genotype of the rs945713 was related to higher scores in the "affective fattening and alogia" dimension; and the A/A genotype of the rs4657181 marker was associated to lower scores in the same dimension. Conclusions: Significant associations of markers inside the NOS1AP gene with schizophrenia and the "affective fattening and alogia" clinical dimension were found. These results are consistent with previous studies and support the possibility that NOS1AP influences schizophrenia susceptibility. Furthermore, NOS1AP might be a modifier of schizophrenia clinical characteristics.
