The LRRK2 (PARK8; OMIM607060) substitution was recently identified as a causative mutation for Parkinson's disease (PD). The pathologic heterogeneity of LRRK2-positive patients suggests that mutation of the LRRK2 gene is associated with the pathogenesis of PD and Parkinson-plus disorders, such as multiple system atrophy (MSA). We previously reported that the G2019S LRRK2 mutation-which is the most common LRRK2 mutation-was not found in a sample of 453 Korean PD patients. In the present study, we extended the screening for the G2019S mutation to a larger group of PD and MSA patients.
We performed a genetic analysis of the G2019S mutation in 877 patients with PD and 199 patients with MSA using a standard PCR and restriction digestion method.
None of the subjects carried the G2019S mutation.
The results of the present study support that the G2019S mutation is extremely rare in PD and is unlikely to be associated with MSA in the Korean population.
LRRK2(PARK8;OMIM607060)取代最近被确定为帕金森病(PD)的致病突变。LRRK2 阳性患者的病理异质性表明,LRRK2 基因突变与 PD 及帕金森病叠加综合征(如多系统萎缩症,MSA)的发病机制有关。我们之前的研究报告称,在 453 名韩国 PD 患者样本中未发现最常见的 LRRK2 突变 G2019S。在本研究中,我们将 G2019S 突变的筛查扩大到了更大的 PD 和 MSA 患者群体。
我们使用标准的 PCR 和酶切方法对 877 名 PD 患者和 199 名 MSA 患者的 G2019S 突变进行了遗传分析。
所有受试者均未携带 G2019S 突变。
本研究结果支持 G2019S 突变在韩国人群中极为罕见,不太可能与 MSA 相关。
