Am J Med Genet B Neuropsychiatr Genet 2015; 168:544-56. [PMID: 26079129 PMCID: PMC4851708 DOI: 10.1002/ajmg.b.32329] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2015] [Accepted: 05/22/2015] [Indexed: 12/28/2022]
Abstract
We comprehensively examined the rare variants in the IPO11-HTR1A region to explore their roles in neuropsychiatric disorders. Five hundred seventy-three to 1,181 rare SNPs in subjects of European descent and 1,234-2,529 SNPs in subjects of African descent (0 < minor allele frequency (MAF) < 0.05) were analyzed in a total of 49,268 subjects in 21 independent cohorts with 11 different neuropsychiatric disorders. Associations between rare variant constellations and diseases and associations between individual rare variants and diseases were tested. RNA expression changes of this region were also explored. We identified a rare variant constellation across the entire IPO11-HTR1A region that was associated with attention deficit hyperactivity disorder (ADHD) in Caucasians (T5: P = 7.9 × 10(-31) ; Fp: P = 1.3 × 10(-32) ), but not with any other disorder examined; association signals mainly came from IPO11 (T5: P = 3.6 × 10(-10) ; Fp: P = 3.2 × 1 0(-10) ) and the intergenic region between IPO11 and HTR1A (T5: P = 4.1 × 10(-30) ; Fp: P = 5.4 × 10(-32) ). One association between ADHD and an intergenic rare variant, i.e., rs10042956, exhibited region- and cohort-wide significance (P = 5.2 × 10(-6) ) and survived correction for false discovery rate (q = 0.006). Cis-eQTL analysis showed that, 29 among the 41 SNPs within or around IPO11 had replicable significant regulatory effects on IPO11 exon expression (1.5 × 10(-17) ≤P < 0.002) in human brain or peripheral blood mononuclear cell tissues. We concluded that IPO11-HTR1A was a significant risk gene region for ADHD in Caucasians.

Abstract
Migraine, a very common headache disorder, is regarded as a polygenic disease and serotonergic pathways appear to play a major role in its pathogenesis. The present study was designed to explore the associations of polymorphisms of 5-hydroxytryptamine (serotonin) receptor 1A (5-HT1A) and 5-hydroxytryptamine receptor 1B (5-HT1B) genes in Turkish migraine patients. 5-HT1A C-1019G (rs6295) promoter and 5-HT1B G861C (rs6296) exon polymorphisms in 203 migraine patients and 202 healthy subjects were analyzed by using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) analysis. Allele and genotype frequencies were not significantly different between migraine patients and healthy subjects for both the 5-HT1A C-1019G promoter and 5-HT1B G861C exon polymorphisms. Our data do not support the hypothesis that 5-HT1A C-1019G and 5-HT1B G861C polymorphisms have effects on migraine.

Rs6295 promoter variants of the serotonin type 1A receptor are differentially activated by c-Jun in vitro and correlate to transcript levels in human epileptic brain tissue. Brain Res 2013; 1499:136-44. [PMID: 23333373 DOI: 10.1016/j.brainres.2012.12.045] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2012] [Revised: 12/19/2012] [Accepted: 12/29/2012] [Indexed: 01/20/2023]
Abstract
Many brain disorders, including epilepsy, migraine and depression, manifest with episodic symptoms that may last for various time intervals. Transient alterations of neuronal function such as related to serotonin homeostasis generally underlie this phenomenon. Several nucleotide polymorphisms (SNPs) in gene promoters associated with these diseases have been described. For obvious reasons, their regulatory roles on gene expression particularly in human brain tissue remain largely enigmatic. The rs6295 G-/C-allelic variant is located in the promoter region of the human HTR1a gene, encoding the G-protein-coupled receptor for 5-hydroxytryptamine (5HT1AR). In addition to reported transcriptional repressor binding, our bioinformatic analyses predicted a reduced binding affinity of the transcription factor (TF) c-Jun for the G-allele. In vitro luciferase transfection assays revealed c-Jun to (a) activate the rs6295 C- significantly stronger than the G-allelic variant and (b) antagonize efficiently the repressive effect of Hes5 on the promoter. The G-allele of rs6295 is known to be associated with aspects of major depression and migraine. In order to address a potential role of rs6295 variants in human brain tissue, we have isolated DNA and mRNA from fresh frozen hippocampal tissue of pharmacoresistant temporal lobe epilepsy (TLE) patients (n=140) after epilepsy surgery for seizure control. We carried out SNP genotyping studies and mRNA analyses in order to determine HTR1a mRNA expression in human hippocampal samples stratified according to the rs6295 allelic variant. The mRNA expression of HTR1a was significantly more abundant in hippocampal mRNA of TLE patients homozygous for the rs6295 C-allele as compared to those with the GG-genotype. These data may point to a novel, i.e., rs6295 allelic variant and c-Jun dependent transcriptional 5HT1AR 'receptoropathy'.

Functional gene variants of the serotonin-synthesizing enzyme tryptophan hydroxylase 2 in migraine. J Neural Transm (Vienna) 2009; 116:815-9.

Abstract
Serotonin (5-HT) plays an important role in the pathophysiology of migraine. Tryptophan hydroxylase 2 (TPH2) is the rate-limiting enzyme in the biosynthesis of 5-HT in the brain and is therefore a major factor in the availability of 5-HT and its rate of production. We hypothesized that functional TPH2 gene variants are associated with migraine. In a case-control study approach, two proven functional and two putatively functional variants of the TPH2 gene were investigated in 266 migraine patients and 153 controls. Genotype, allele, and haplotype frequencies did not differ between healthy subjects and migraineurs. A subgroup analysis for the occurrence of aura or clinical characteristics, including the number of attacks, did not reveal a positive association for the investigated polymorphisms. Our data argue against a major influence of the TPH2 gene promoter region in migraine.

Abstract
The serotonin-1A (5-HT1A) receptor serves as a hub to regulate the activity and actions of the serotonin system, and is expressed both as a presynaptic autoreceptor on raphe neurons, and as a major postsynaptic receptor in hippocampal, cortical, and hypothalamic regions involved in mood, emotion and stress response. As such, the level of expression of 5-HT1A receptors is implicated in the development of anxiety and depression phenotypes. This review focuses on the C(-1019)G (rs6295) promoter polymorphism of the 5-HT1A receptor gene (HTR1A) and its effect on the activity of transcription factors that recognize the C-allele, including Deaf-1, Hes1 and Hes5; its effects on 5-HT1A receptor expression in pre- and postsynaptic areas; as well as its implication in early postnatal development and adult neurogenesis in the hippocampus and cortex. Although several studies have now replicated the association of the G-allele with depression, panic disorder, neuroticism, and reduced response to antidepressant or antipsychotic treatment, ethnic, disease and genetic heterogeneity among subjects in different studies may obscure such associations. Gene-gene interaction studies suggest that the 5-HT1A receptor G(-1019) allele is a risk allele which could be used as a marker for depression and related mood disorders. Finally, association of the G(-1019) allele with increased raphe 5-HT1A binding potential, increased amygdala reactivity to emotional stimuli, and reduced amygdala volume, particularly in disease states, suggests a functional role for the C(-1019)G site in 5-HT1A receptor dys-regulation and predisposition to mental illness.
