Association of lectin-like oxidized low density lipoprotein receptor 1 () polymorphisms with late-onset Alzheimer disease in Han Chinese.

Background: Lectin-like oxidized low density lipoprotein receptor 1 (OLR1) locates within the area of chromosome 12p, which has been identified as the AD-susceptible region, and plays a role in lipid metabolism. Therefore, it has been suggested to be a good candidate gene for Alzheimer's disease (AD). Several SNPs within OLR1 have been reported to have association with AD among Caucasians.

FERMT2 rs17125944 polymorphism with Alzheimer's disease risk: a replication and meta-analysis.

A recent meta-analysis of genome-wide association studies (GWAS) in population of Caucasian identified a single nucleotide polymorphism (SNP) rs17125944 in the FERMT2 gene as a new susceptibility locus for late-onset Alzheimer's disease (LOAD). In order to validate the association of the rs17125944 polymorphism with LOAD risk in the northern Han Chinese, we recruited a case-control study of 2338 Han Chinese subjects (984 cases and 1354 age- and gender-matched controls). Our results demonstrated that there was no significant association between the rs17125944 polymorphism and LOAD (genotype: P = 0.

MEF2C rs190982 polymorphism with late-onset Alzheimer's disease in Han Chinese: A replication study and meta-analyses.

The myocyte enhancer factor (MEF2) family of transcription factors plays a vital role in memory and learning due to its functions in regulating synapse number and reducing dendritic spines. Myocyte enhancer factor 2 C (MEF2C) is regarded as modulator of amyloid-protein precursor (APP) proteolytic processing, in which amyloid-β (Aβ) is produced. A common single nucleotide polymorphism (SNP, rs190982) in MEF2C gene was identified to be related to late-onset Alzheimer's disease (LOAD) in Caucasians in a large meta-analysis of genome-wide association studies (GWAS).

INPP5D rs35349669 polymorphism with late-onset Alzheimer's disease: A replication study and meta-analysis.

Inositol polyphosphate-5-phosphatase (INPP5D) was reported to be associated with Alzheimer's disease (AD) through modulating the inflammatory process and immune response. A recent genome-wide association study discovered a new locus single nucleotide polymorphism (SNP, rs35349669) of INPP5D which was significantly associated with susceptibility to late-onset Alzheimer's disease (LOAD) in Caucasians. In this study, we investigated the relations between the INPP5D polymorphism rs35349669 and LOAD in Han Chinese population comprising 984 LOAD cases and 1352 healthy controls being matched for age and gender.

Associations of rs3740677 within GAB2 Gene with LOAD in Chinese Han Population.

GRB2-associated binding protein 2 (GAB2) has been identified as a crucial factor in Alzheimer's disease (AD), and ten common variants within GAB2 have been detected to be associated with AD onset risk in genome-wide association studies (GWAS). Here, we first screened a common locus (rs3740677) in 3' UTR of GAB2 sequence which is targeted by the miRNA-185 and initiatively explored the probable associations of rs3740677 with risk for late-onset AD (LOAD) in a large scale case-control study from Chinese Han populations (992 LOAD patients and 1358 healthy subjects). Eventually, the genotype (P = 0.

Association of DISC1 Polymorphisms with Late-Onset Alzheimer's Disease in Northern Han Chinese.

The disrupted-in-schizophrenia-1 (DISC1) is a candidate gene for psychiatric diseases and plays various roles in brain development. It has been reported as a candidate gene for Alzheimer's disease (AD) in a recent large genome-wide association study in Caucasians. To explore the associations between DISC1 and AD, we performed a case-control study including 2318 subjects in Northern Han Chinese.

Association of HMGCR polymorphism with late-onset Alzheimer's disease in Han Chinese.

The 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR) acts as a potential genetic modifier for Alzheimer's disease (AD). Previous reports identified that HMGCR rs3846662 polymorphism is associated with biosynthesis of cholesterol in AD pathology. In order to assess the involvement of the HMGCR polymorphism in the risk of late-onset AD (LOAD) in northern Han Chinese, we performed a case-control study of 2334 unrelated subjects (984 cases and 1350 age- and gender-matched controls) to evaluate the genotype and allele distributions of the HMGCR rs3846662 with LOAD.

SORL1 Is Associated with the Risk of Late-Onset Alzheimer's Disease: a Replication Study and Meta-Analyses.

The sorting-related receptor gene (SORL1) has been defined as an interesting candidate gene for Alzheimer's disease (AD). Recently, one novel variant, rs11218343, within SORL1 was reported to be related to late-onset Alzheimer's disease (LOAD) in Caucasians, Korean, and Japanese. The aim of this case-control study is to investigate whether SORL1 rs11218343 contributes to susceptibility for LOAD in Chinese.

PGRN Is Associated with Late-Onset Alzheimer's Disease: a Case-Control Replication Study and Meta-analysis.

Progranulin (PGRN) plays an important role in Alzheimer's disease (AD) through participating in altering neurite outgrowth and neuronal survival. Previous studies identified that rs5848 in the 3'-untranslated region (3'-UTR) of the PGRN gene (GRN) is strongly associated with AD in Caucasians. In order to assess the involvement of the GRN polymorphism in the risk of late-onset AD (LOAD), we analyzed the genotype and allele distributions of rs5848 in 2350 Han Chinese subjects (AD, 992; control, 1358).
