Association between RELN polymorphisms and schizophrenia in a Han population from Northeast China
1Department of Epidemiology and Biostatistics, School of Public Health, Jilin University, Changchun, Jilin Province, China.
Objective:
To explore the association between the RELN gene and schizophrenia in the overall sample and samples stratified by sex in a northeastern Chinese population.
Methods:
A total of 1536 participants from Jilin Province, China, were recruited in this case-control study. Four single nucleotide polymorphisms (rs1062831, rs3808039, rs362746, and rs736707) in the RELN gene were genotyped. Binary logistic regression analysis was applied to detect associations between the genotypes of each single nucleotide polymorphism and schizophrenia. P values of no more than 0.003125 [0.05/(4 SNPs*4 different genetic models)] after Bonferroni correction were considered statistically significant.
Results:
All single-nucleotide polymorphisms conformed to Hardy-Weinberg equilibrium in the control group. Logistic regression analysis revealed that after Bonferroni correction, rs362746 was associated with schizophrenia under the recessive model (P = 0.001) and codominant model (P = 0.003) in the overall group. The association between schizophrenia and RELN single-nucleotide polymorphisms was not found in a sex-specific pattern after Bonferroni correction.
Conclusion:
Our study provides and supports the evidence that RELN is a candidate gene for schizophrenia. Replication studies conducted in different populations are required, and the sex-specific association of this gene with schizophrenia warrants further exploration.

Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...
10:10The Implicit Association Test
One of the core constructs in social psychology is the notion of an attitude toward an object or person. Traditionally, psychologists measured attitudes by simply asking people to self-report their beliefs, opinions, or feelings. This approach has limitations, however, when measuring socially sensitive attitudes, like racial prejudice, because people are often motivated to self-report unprejudiced, egalitarian beliefs (despite...
