Abstract

The etiology of Parkinson's disease (PD), a neurodegenerative disorder, is still unknown and the role of genetic factors have been implicated. XRCC1 (X-Ray Repair Cross-Complementingin) protein is required for DNA single-strand break repair and interacts with poly-ADP-ribose-polymerase (PARP), DNA-ligase III and DNA polymerase beta. It has been shown by mouse models that PARP may have a role in the pathogenesis of various diseases including PD. The aim of the study is to investigate the association of PD with XRCC1 gene Arg399Gln polymorphism. Seventy-one unrelated PD patients (50 male, 21 female) and 76 healthy age and sex matched volunteers (53 male, 23 female) have been included in the study. Molecular analyses have been performed with Polymerase Chain Reaction (PCR) and Restriction Fragment Length Polymorphism (RFLP) methods. The relationship between the XRCC1 gene Arg399Gln polymorphism and the PD risk has been investigated with the binary logistic regression analysis. No statistically significant relation has been determined between the PD and control groups (p=0,364). The present study is the first research about the relationship between the DNA repair genes and PD in the literature and does not show any relationship between PD and XRCC1 gene Arg399Gln polymorphism in Turkish population. Further studies with larger sample sizes will reveal more information about the genetic polymorphisms in DNA repair genes for the risk and the etiopathogenesis of PD.

Özet

Nörodejeneratif bir hastalık olan Parkinson hastalığında (PH) etyoloji halen bilinmemekle birlikte genetik faktörlerin rolü giderek önem kazanmaktadır. XRCC1 (X-Ray Repair Cross-Complementingin) proteini DNA tek sarmal kırıklarının onarımı için gereklidir ve poli-ADP-riboz-polimeraz (PARP), DNA-ligaz III ve DNA-polimeraz-beta ile etkileşerek işlev görür. PH'nin de aralarında bulunduğu bir grup hastalıkta PARP etkilenmesinin patogenezde rol oynayabileceği hayvan modellerinde gösterilmiştir. Bu çalışmada XRCC1 399 gen polimorfizmiyle PH arasındaki ilişkinin araştırılması amaçlanmıştır. Çalışmaya akraba olmayan 71 PH olgusu (50 erkek, 21 kadın) ve 76 (53 erkek, 23 kadın) sağlıklı gönüllü birey dahil edilmiş, moleküler analiz Polimer Zincir Reaksiyonu (PCR) ve Restriksiyon Parça Uzunluk Polimorfizmi (RFLP) yöntemi ile belirlenmiştir. XRCC1 399 gen polimorfizmi ile PH arasındaki ilişki ikili lojistik regresyon analiziyle incelenmiş, hasta ve kontrol grupları arasında istatistiksel olarak anlamlı bir ilişki tespit edilmemiştir (p=0,364). DNA tamir genleri ve PH arasındaki ilişkiyi araştıran bu literatürdeki ilk çalışmada PH ve XRCC1 Arg399Gln gen polimorfizmi arasında Türk hasta grubunda bir ilişki gösterilememiştir. Daha geniş örneklem büyüklüğüyle yapılacak ileri çalışmalar, DNA tamir genlerindeki genetik polimorfizmlerin PH gelişim riski ve etyopatogenezindeki rolü hakkında daha fazla bilgi sağlayacaktır.
