Association and gene–gene interactions study of reelin signaling pathway related genes with autism in the Han Chinese population / Yidong SHEN in Autism Research, 9-4 (April 2016)
[article]
Titre : Association and gene–gene interactions study of reelin signaling pathway related genes with autism in the Han Chinese population Type de document : Texte imprimé et/ou numérique Auteurs : Yidong SHEN, Auteur ; Guanglei XUN, Auteur ; Hui GUO, Auteur ; Yiqun HE, Auteur ; Jianjun OU, Auteur ; Huixi DONG, Auteur ; Kun XIA, Auteur ; Jingping ZHAO, Auteur Article en page(s) : p.436-442 Langues : Anglais (eng) Mots-clés : autism reelin signaling pathway interaction polymorphism Index. décimale : PER Périodiques Résumé : Autism is a neurodevelopmental disorder with unclear etiology. Reelin had been proposed to participate in the etiology of autism due to its important role in brain development. The goal of this study was to explore the association and gene–gene interactions of reelin signaling pathway related genes (RELN, VLDLR, LRP8, DAB1, FYN, and CDK5) with autism in Han Chinese population. Genotyping data of the six genes were obtained from a recent genome-wide association study performed in 430 autistic children who fulfilled the DSM-IV-TR criteria for autistic disorder, and 1,074 healthy controls. Single marker case-control association analysis and haplotype case-control association analysis were conducted after the data was screened. Multifactor dimensionality reduction (MDR) was applied to further test gene–gene interactions. Neither the single marker nor the haplotype association tests found any significant difference between the autistic group and the control group after permutation test of 1,000 rounds. The 4-locus MDR model (comprising rs6143734, rs1858782, rs634500, and rs1924267 which belong to RELN and DAB1) was determined to be the model with the highest cross-validation consistency (CVC) and testing balanced accuracy. The results indicate that an interaction between RELN and DAB1 may increase the risk of autism in the Han Chinese population. Furthermore, it can also be inferred that the involvement of RELN in the etiology of autism would occur through interaction with DAB1.

Titre : Genome-wide association analysis of autism identified multiple loci that have been reported as strong signals for neuropsychiatric disorders Type de document : Texte imprimé et/ou numérique Auteurs : Lu XIA, Auteur ; Jianjun OU, Auteur ; Kuokuo LI, Auteur ; Hui GUO, Auteur ; Zhengmao HU, Auteur ; Ting BAI, Auteur ; Jingping ZHAO, Auteur ; Kun XIA, Auteur ; Fengyu ZHANG, Auteur Article en page(s) : p.382-396 Langues : Anglais (eng) Mots-clés : autism genome-wide association study neuropsychiatric disorders transmission disequilibrium test Index. décimale : PER Périodiques Résumé : Autism is a common neurodevelopmental disorder with a moderate to a high degree of heritability, but only a few common genetic variants that explain the heritability have been associated. We performed a genome-wide transmission disequilibrium test analysis of a newly genotyped autism case-parent triad samples (127 trios) in Han Chinese, identified top association signals at multiple single nucleotide polymorphisms (SNPs), including rs9839376 (OR = 2.59, P = 1.27 x 10(-05) ) at KCNMB2, rs6044680 (OR = 0.319, P = 4.82 x 10(-05) ) and rs7274133 (OR = 0.313, P = 3.22 x 10(-05) ) at PCSK2, and rs310619 (OR = 2.40, P = 7.44 x 10(-05) ) at EEF1A2. Furthermore, a genome-wide combined P-value of individual SNPs in two independent case-parent triad samples (total 402 triads, n = 1,206) identified SNPs at EGFLAM, ZDHHC2, AGBL1, and SNX29 as additional association signals for autism. While none of these signals achieved a genome-wide significance in the two samples of our study, they have been reported in a previous genome-wide association study of neuropsychiatric disorders, and the majority of these SNP have a significant cis-regulatory association with mRNA in human tissues (false discovery rate (FDR) < 0.05). Our study warrants further study or replication with additional sample for association with autism and other neuropsychiatric disorders. Autism Res 2020, 13: 382-396. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Autism is a common neurodevelopmental disorder, heritable, but only a few common genetic variants that explain the heritability have been associated. We conducted a genome-wide association study with two cohorts of autism case-parent triad samples in Han Chinese and identified multiple single nucleotide polymorphisms that were reported as strong association signals in a previous genome-wide association study of other neuropsychiatric disorders or related traits. Our study provides evidence for shared genetic variants among autism and other neuropsychiatric disorders.
