title: Analysis of LINGO1 (rs9652490) polymorphism in sporadic Parkinson's disease in a Polish population, and a meta-analysis.
abstract: Recently, a variant in LINGO1 (also denominated as LRRN6A) rs9652490:A>G gene has been found to associate with increased risk of essential tremor (ET). Because ET and Parkinson's disease (PD) may be ethiologically related, we proceeded to conduct an analysis of the SNP in PD population. In the current study LINGO1 rs9652490:A>G polymorphism was evaluated in a cohort of 162 Polish patients diagnosed with PD and 177 controls by means of MALDI-TOF mass spectrometry. Any significant differences in rs9652490 genotype or allele frequencies between the studied groups were noted. Our findings demonstrate that LINGO1 SNP (rs9652490) is not associated with sporadic PD in our Polish cohort. A meta-analysis of the available data suggests protective role of rs9652490GG genotype (OR 0.70, 95% CI: 0.51-0.96, p=0.028).
