Assessment of risk factor variants of LRRK2, MAPT, SNCA and TCEANC2 genes in Hungarian sporadic Parkinson's disease patients
Introduction: Parkinson's disease is the second most common neurodegenerative disease. Lifestyle, environmental effects and several genetic factors have been proposed to contribute to its development. Though the majority of PD cases do not have a family history of disease, genetic alterations a...

| 520 | 3 | |a Introduction: Parkinson's disease is the second most common neurodegenerative disease. Lifestyle, environmental effects and several genetic factors have been proposed to contribute to its development. Though the majority of PD cases do not have a family history of disease, genetic alterations are proposed to be present in 60 percent of the more common sporadic cases. Objective: The aim of this study is to evaluate the frequency of PD related specific risk variants of LRRK2, MAPT, SNCA and PARK10 genes in the Hungarian population. Out of the ten investigated polymorphisms three are proposed to have protective effect and seven are putative risk factors. Methods: For genotyping, TaqMan allelic discrimination and restriction fragment length polymorphism method was used. LRRK2 mutations were investigated among 124 sporadic PD patients and 128 healthy controls. MAPT and SNCA variant frequencies were evaluated in a group of 123 patients and 122 controls, while PARK10 variant was studied in groups of 121 patients and 113 controls. Results: No significant difference could be detected in the frequencies of the investigated MAPT and PARK10 variants between the studied Hungarian PD cases and controls. The minor allele of the risk factor S1647T LRRK2 variant was found to be more frequent among healthy male individuals compared to patients. Moreover, in the frequency of one of the investigated SNCA variant a significant intergroup difference was detected. The minor allele (A) of rs356186 is proposed to be protective against developing the disease. In accord with data obtained in other populations, the AA genotype was significantly more frequent among Hungarian healthy controls compared to patients. Similarly, a significant difference in genotype distribution was also found in comparison of patients with late onset disease to healthy controls, which was due to the higher frequency of AG genotype among patients. Conclusion: The frequencies of different gene variants show great differences in populations. Assessment of the frequency of variants of PD related genes variants is important in order to uncover the pathomechanisms underlying the disease, and to identify potential therapeutic targets. This is the first comprehensive study focusing on these genetic variants in the population of East-Central European region. Our results extend the knowledge on the world wide occurrence of these polymorphisms by demonstrating the occurrence of specific alleles and absence of others in Hungarian PD patients. © 2019 Elsevier B.V. | |
