Determining association of rho kinase 1 gene polymorphisms with risk of Alzheimer's disease: a multicenter pilot study.

ABSTRACT: Background:In addition to the increasing evidence for a molecular mechanism of rho kinase 1 (ROCK1) in Alzheimer's disease (AD), there are several published studies regarding the relationship between ROCK1 gene polymorphisms and neurological diseases. However, it is unknown whether there is an association between the polymorphisms of ROCK1 and AD. We sought to identify the potential association between ROCK1 gene polymorphisms and AD in the Chinese Han population. Methods:A total of 295 patients with AD and 206 healthy controls from multiple centers were enrolled in this study. Three single-nucleotide polymorphisms (SNPs) (rs35996865, rs11873284, and rs2127958) in ROCK1 gene were analyzed using Sanger sequencing. Results:We did not find any significant differences between AD and control groups with regards to the frequency of these three ROCK1 polymorphisms. Further, the three SNP genotype frequencies and allele frequencies did not show significant differences between patients of AD and controls in APOE4-stratified subjects (P>0.01). Additionally, the three SNPs did not show significant differences even when adopting a four-inheritance model by logistic regression. Conclusions:This is the first multicenter pilot study to evaluate the contribution of ROCK1 genetic variance to AD risk. Our data demonstrated that the ROCK1 gene may not influence the risk of AD by interacting with APOE among Chinese Han people.

Project description:Psoriasis is a complex genetic disease, which has previously been associated with numerous single nucleotide polymorphisms (SNPs) that are implicated in various processes, including skin barrier functions and in the regulation of inflammatory and immune responses. The present study aimed to investigate the genotypic and allelic frequencies of 32 SNPs at 24 genetic loci, and their association with psoriasis in a Mexican population. These SNPs, which were associated with psoriasis in previous studies, included the following genes: Major histocompatibility complex class I-C (HLA-C), interleukin (IL)-12B, IL-23R, IL-23A, IL-28RA, tumor necrosis factor (TNF)-?, ring finger protein-114 (RNF114), cyclin-dependent kinase 5 regulatory subunit-associated protein 1-like 1, late cornified envelope 3B/3C, signal transducer and activator of transcription 4, LINC01185, interferon induced with helicase C domain 1, IL-13, TNF-?-induced protein 3 (TNFAIP3), TNFAIP3 interacting protein 1, endoplasmic reticulum aminopeptidase 1, TNF receptor-associated factor interacting protein 2, Leptin, nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor-alpha, F-box and leucine-rich repeat protein 19, nitric oxide synthase 2, cluster of differentiation 40, nuclear receptor coactivator 5, and ADAM metallopeptidase domain 33. A total of 32 male and 14 female subjects with a clinical diagnosis of chronic plaque psoriasis, as well as 103 control subjects, were analyzed. Molecular analyses were performed using TaqMan® assays in a TaqMan® OpenArray® Genotyping system. Results were analyzed using the Golden Helix SNP and Variation Suite 7 program. Of the 32 SNPs, six were associated with an increased risk of developing psoriasis, including: HLA-C rs10484554 [allele T: odds ratio (OR) 3.51], IL-12B rs3212227 (allele T: OR 1.88), IL-12B rs3213094 (allele C: OR 1.94), HLA complex group 27 rs1265181 (allele C: OR 2.83), annexin A6 rs17728338 (allele A: OR 2.41), and RNF114 rs6125829 (allele G: OR 1.98). Fisher's exact test detected statistical significance; however, following false discovery rate and Bonferroni correction, this association was no longer significant (threshold for genome-wide significance, P<1.56×10-3). SNPs that were associated with an increased risk of psoriasis in the present study have previously been associated with psoriasis in European, American, and Asian populations. In order to establish genome-wide significance, future studies must analyze a greater sample size. To the best of our knowledge, the present pilot study is the first to investigate the association between these 32 SNPs and psoriasis in a Mexican Mestizo population.
