Neurotrophin-3 gene polymorphism in schizophrenia and its relation with diseases severity and cognitive dysfunction.

ABSTRACT:

Objectives

Synaptic plasticity markers are known to alter in schizophrenia. The objective of the study was to investigate the genotype and allele frequency of neurotrophin-3 (NT-3) gene polymorphism (rs6489630, rs6332, and rs11063714) and plasma NT-3 levels in schizophrenia and their relation with cognitive status.

Materials and methods

The study was conducted on 216 Schizophrenia patients and 216 controls. Single-nucleotide polymorphism (SNP) of NT-3 and its plasma levels were assessed in both groups. Cognitive status was evaluated using Addenbrooke Cognitive examination-III scores.

Results

The rs6489630 polymorphism was found to be significantly associated with the severity of schizophrenia (P = 0.004). The CT genotype (P = 0.02, OR = 1.631 [1.10-2.43]) and minor allele T (P = 0.004, OR = 1.58 [1.16-2.16]) of rs6489630 conferred an increased susceptibility to develop schizophrenia. The rs6332 variant was found to affect cognitive status significantly in schizophrenia (P = 0.040), and memory dysfunction was seen in individuals with AG (P < 0.01) and AA variant (P = 0.03) of rs6332.

Conclusion

We conclude that SNPs of NT-3 enhance the risk of schizophrenia and are related to cognitive dysfunction.

Project description:BackgroundSchizophrenia is a complex psychiatric disorder with unknown etiology. A number of recent studies have shown that the polymorphism of the neural precursor cell expressed developmentally down-regulated 4 (NEDD4) gene is associated with a variety of neuropsychiatric disorders, such as schizophrenia, and may also be associated with cognitive dysfunction in these diseases.MethodsA case-control study was carried out, the alleles and genotypes distributions of five loci (rs3088077, rs2303579, rs7162435, rs11550869, rs62043855) of the NEDD4 gene from 296 schizophrenia patients and 320 healthy controls were detected by using Taqman single-nucleotide polymorphism (SNP) genotyping technology. The clinical data of case and control group members were collected by self-made questionnaire and the psychotic symptoms of case group members were assessed by the Positive and Negative Syndrome Scale (PANSS). The Matrics Consensus Cognitive Battery (MCCB) was used to test the cognitive function of case group members.ResultsThe alleles and genotypes frequency of two loci (rs3088077, rs2303579) between case and control group showed significant differences (P < 0.05). There was no significant difference in MCCB scores of patients with different genotypes at rs3088077, rs11550869 and rs7162435 loci in case group. The study of rs2303579 locus showed that, patients' scores with CT genotype were significantly lower than those with CC and TT genotypes (P < 0.05) in the test of Wechsler Memory Scale-Third Edition (WMS-III): Spatial Span, the scores of patients with TT genotype were significantly higher than those with CT genotype (P < 0.05) in the test of Hopkins Verbal Learning Test-Revised (HVLT-R). The study of rs62043855 locus showed that patients with TG genotype had significantly lower scores than those with GG genotype (P < 0.05) in the test of Neuropsychological Assessment Battery (NAB): Mazes.ConclusionsOur study showed that in schizophrenia patients of Chinese Han population, the polymorphisms of rs3088077 and rs2303579 loci were related to the pathogenesis of schizophrenia, while the polymorphisms of rs2303579 and rs62043855 loci were associated with cognitive dysfunction.
