چکیده
OBJECTIVE Based on a small sample of cases with schizophrenia and control individuals from an isolated population, a genome-wide association study was undertaken to find variants conferring susceptibility to this disease. METHODS Standard association tests were employed, followed by newer multilocus association methods (genotype patterns). RESULTS Individually, no variant produced a significant result. However, the best two variants (rs1360382 on chromosome 9 and rs1303 on chromosome 14) showed significantly different genotype pattern distributions between patients and control individuals. The risk genotype pattern AA-TT is highly predictive of schizophrenia, with estimated sensitivity and specificity of 1 and 0.96, respectively. CONCLUSIONS These findings support the hypothesis that schizophrenia is partly due to multiple genetic variants, each with a relatively small effect.
