Lack of association between urotensin-II (UTS2) gene polymorphisms (Thr21Met and Ser89Asn) and migraine.

ABSTRACT: Migraine is a common neurovascular brain disorder with heterogeneous clinical presentation, including recurrent headache attacks. The pathophysiology of migraine is complex, and a number of genomic regions have been associated with the development of migraine. In this study, we analyzed the allele and genotype frequencies of the urotensin-II gene (UTS2) polymorphisms, Thr21Met and Ser89Asn, among Turkish patients with migraine. A total of 146 patients with migraine (14 with aura [MA group] and 132 without aura [MO group]) were genotyped for Thr21Met and Ser89Asn polymorphisms and compared with 154 age- and sex-matched healthy controls. The UTS2 gene polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). No significant differences were observed in allele and genotype frequencies for Thr21Met and Ser89Asn polymorphisms between the patients with migraine and control group. Similarly, we did not observe significant differences in allele and genotype frequencies between MA and MO and control group. Moreover, the haplotype analysis showed no association between UTS2 gene haplotypes (MN, MS, TN, and TS) and migraine. In summary, Thr21Met and Ser89Asn polymorphisms of the UTS2 gene are not risk factors for migraine in our sample of Turkish migraine patients.

Project description:INTRODUCTION: Migraine is a chronic, neurovascular polygenic disease where genetic and environmental factors are involved in its etiology. Dysfunction of neuronal ion transportation can provide a model for predisposition for common forms of migraine. Mutations in genes encoding ion channels disturb the rhythmic function of exposed tissue that may also explain the episodic nature of migraine. Our aim was to study the single nucleotide polymorphisms of CACNA1A gene in migraine patients. MATERIALS AND METHODS: The subjects were the patients of migraine, in the age range of 18-80 years, diagnosed by a Neurologist, as per the diagnostic criteria of International Headache Society (IHS) Classification 2004 after excluding other causes of headache by clinical examination and relevant investigations. The controls were the age and sex matched healthy persons from the same population excluding the relatives of patients. Only those patients and the controls, who voluntarily participated in the study, were taken and their blood samples were taken for the study. Deoxyribonucleic acid (DNA) extraction was performed according to the manufacturer's protocol for Qiagen DNA extraction kits (Qiagen, Hilden, NRW, Germany). DNA content was quantified by spectrophotometric absorption (Nanodrop Spectrophotometer, BioLab, Scoresby, VIC, Australia). Polymerase chain reaction was performed using an iCycler Thermal Cycler (Bio.Rad, Hercules, CA, USA). The polymorphic analysis of CACNA1A gene was carried out by two methods: Restriction fragment length polymorphism and sequencing. RESULTS: The study included a total of 25 patients of migraine, diagnosed on out-patient department basis as per IHS Classification 2004 and compared with age and sex matched 25 healthy controls. Most of the patients 23 (92%) were below the age of 50 years. 20 of the patients (80%) were females and 5 (20%) were males. The polymorphic analysis of CACNA1A gene revealed the presence of only the wild form of the gene for the codon E993V in both case and control groups. CONCLUSION: In our study, we could not find any polymorphism of CACNA1A gene in the selected patients. Instead the wild type of genotype was found in both patients and controls. This negative result presented here, implies that if the CACNA1A gene is involved in typical migraine (with and without aura), its contribution is very modest and therefore difficult to discern. Nevertheless, there are other genes that could be considered potential candidates for typical migraine susceptibility for which further research is needed.
