Abstract
Recent studies have shown that long noncoding RNAs contribute to the pathogenesis of bipolar disorder (BD). In this study, we genotyped four HOX Transcript Antisense Intergenic RNA (HOTAIR) gene polymorphisms to investigate if these variations could affect the risk of BD and its clinical subtypes. A total of 357 subjects, comprised of 194 BD patients and 163 age-matched healthy controls, were enrolled. Genotyping was carried out using PCR-RFLP and ARMS-PCR methods. We detected significant associations between the HOTAIR gene rs1899663 G/T, rs12826786 C/T, rs4759314 A/G, and rs920778 C/T polymorphism and the risk of BD under allelic, recessive, dominant, and codominant contrasted genetic models. The CT genotype of rs920778 C/T, GT genotype of rs1899663 G/T, and CT genotype of rs12826786 C/T polymorphisms enhanced the risk of BD type II (BDII). In contrast, the GG genotype of rs4759314 A/G polymorphism significantly diminished BDII risk by 83%. A positive association was noticed between CTTA and CTCG haplotypes of rs920778/rs1899663/rs12826786/rs4759314 and BD risk. Our findings reveal an interactive effect of HOTAIR polymorphisms on the development of BD and its subtypes. Further functional studies are needed to elucidate the role of these variations on HOTAIR expression and epigenetic status.

Abstract
AbstractWe investigated the genotype frequency of methylenetetrahydrofolate reductase (MTHFR) 1298A > C polymorphism in the group of patients with bipolar disorder type I (BDI) (n = 200) and schizophrenia (n = 200) and in the control group (n = 300). Odds ratio (OR) for patients with BD and schizophrenia in 1298CC homozygous state was 3.768 (95% CI = 1.752–8.104); P = 0.0003; (P = 0.0006 after Bonferroni correction) and 2.694; (95% CI = 1.207–6.013); P = 0.0123 (P = 0.0246 after Bonferroni correction), respectively. The stratification of patients based on gender revealed significant association of 1298CC genotype with female patients only with BDI (OR = 7.293; 95% CI = 2.017–26.363; P = 0.0005).Our results confirm association of BD and schizophrenia with the 1p36.3 MTHFR locus and with the methyl group transfer using folate-dependent one-carbon pathway.

Abstract
This study examined the association of plasma homocysteine levels and the methylenetetrahydrofolate reductase (MTHFR) gene polymorphism with schizophrenia in the Han population residing in northern China. We detected the MTHFR C677T genotype in 123 schizophrenia patients and compared it with the genotype of 123 controls by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). In addition, by using the cyclophorase method, the plasma homocysteine concentration in 62 schizophrenia patients was determined and then compared with that in 62 controls; these 62 patients and 62 controls were a subset of the 123 patients and 123 controls. We found that the homocysteine levels in the patients were significantly higher than those in the controls. The frequency of homozygosity for the 677T allele of the MTHFR gene was higher in the patient group than in the control group, and the difference between the two groups was statistically significant for both the MTHFR genotype and the frequency of allele homozygosity. A significant difference was observed in the plasma homocysteine levels among the different genotypes in the patient and control groups. In conclusion, both elevated plasma homocysteine levels and variation in the MTHFR 677C-->T gene are related to increased rates of schizophrenia and are risk factors for schizophrenia.

Abstract
We investigated the effect of polymorphic variants of c.1298A>C (Glu429Ala) and c.677C>T (Ala222Val) in methylenetetrahydrofolate (MTHFR) gene on the total homocysteine (tHcy), folate and B12 levels in patients with bipolar disorder, first-degree relatives of patients, and controls. The c.677C>T and c.1298A>C polymorphisms in MTHFR were determined by polymerase chain reaction-restriction fragment length polymorphism in 197 bipolar patients, 278 relatives and 238 controls. tHcy and folate and vitamin B12 levels were measured by Fluorescence Polarization Immunoassay and Electrochemiluminescence, respectively. The tHcy was significantly increased in patients and relatives. In contrast, folate and B12 were significantly lower in patients and relatives. Gender was not considered as a significant determinant in the multivariate analysis. Genotypes of c.1298A>C and c.677C>T were correlated with tHcy, folate and B12. Patients and relatives carrying TT and/or AA and AC genotypes had elevated tHcy and reduced folate and B12 levels. High tHcy but low folate and vitamin B12 levels may be a risk factor for development of bipolar disorder.

Abstract
BACKGROUND The etiology of bipolar disorder (BD) and schizophrenia is very complex. Polymorphic variants of genes encoding enzymes of the monoaminergic may be involved in development of BD and schizophrenia. Therefore, we examined the prevalence of 1958G>A polymorphism of MTHFD1 gene, encoding trifunctional folate enzyme 5,10-methylenetetrahydrofolate dehydrogenase, 5,10-methenyltetrahydrofolate cyclohydrolase and 10-formyltetrahydrofolate synthetase (MTHFD1), and 2756A>G variant of methionine synthase (MTR) gene in patients with BD (n=200), schizophrenia (n=200) and in controls (n=300). OBJECTIVE We investigated the genotypic and allelic frequencies of MTHFD1 1958G>A (R653Q) and MTR 2756A>G (D919G) gene polymorphisms in a group of bipolar (n=200) and schizophrenic patients (n=200), as well as in controls (n=300). METHODS The distributon of genotypes in all groups was tested for deviation from Hardy-Weinberg equilibrium (HWE). The Pearson's chi-square (chi) test and Fisher's exact test were applied to assess differences in the genotypic and allelic (respectively) distribution between groups of patients and controls. MAIN RESULTS We found that MTHFD1 1958AA or 1958AG genotypes constitute risk factors for development of bipolar disorder type I (BDI) or schizophrenia with odds ratios (OR)=1.743 (95% CI=1.211-2.508; P=0.0027; P (corr)=0.0054) and 2.667 (95% CI=1.845-3.854; P=0.0001; P (corr)=0.0002), respectively. In the same groups, the MTR 2756GG or 2756AG genotypes also constitute significant risk factors in occurrence of BDI and schizophrenia with OR=1.621 (95% CI=1.130-2.326; P=0.0086; P (corr)=0.0172) and 1.556 (95% CI=1.085-2.232; P=0.0160; P (corr)=0.032), respectively. Gender classification of patients indicated significant association only of MTHFD1 1958A allele with BDI and schizophrenia in the male patients OR=1.838 (95% CI=1.114-3.031; P=0.0166; P (corr)=0.0332) and OR=3.964 (95% CI=2.358-6.663; P=0.0001 P (corr)=0.0002), respectively. CONCLUSION Since MTHFD and MTR genes are located in 14q24 and 1q43 loci, our findings support the significance of chromosomes 14q and 1q in etiopathogenesis of bipolar disorder and schizophrenia.

Abstract
Methylenetetrahydrofolate reductase (MTHFR) gene polymorphism 677C>T has been shown to be a risk factor for psychiatric disorders. We investigated the genotype and allelic frequencies of MTHFR 677C>T polymorphism in the group of patients with bipolar disorder type I (BDI) (n=200) and schizophrenia (n=200), and in the control group (n=300). Odds ratio (OR) for patients with BD and schizophrenia with 677T allele was 1.988 ((95% CI=1.370-2.883); P=0.0003 (P=0.0006 after Bonferroni correction)) and 1.796 ((95% CI=1.237-2.609); P=0.0020 (P=0.0040 after Bonferroni correction)), respectively. The stratification of patients based on gender revealed significant association of 677T allele with male patients with BDI and schizophrenia (OR=2.393; 95% CI=1.429-4.006; P=0.0008 and OR=2.036; 95% CI=1.207-3.433; P=0.0073, respectively). This finding indicates possible association of BD and schizophrenia with the 1p36.3 MTHFR locus.
