Am J Med Genet. It is probable that some of the undiscovered rare alleles affecting risk for SCZ confer protection but larger sample sizes are needed to determine this unequivocally. We decided to revisit this hypothesis using this dataset, which is subject to more stringent quality control parameters and uses three algorithms to call CNVs, rather than one. The sixteen loci that remain after these additional QC steps, comprising seventeen separate association signals, are listed in Table 1. Gene-set burden was tested using logistic regression deviance test 6. After quality control see Quality Control section for details , a total of samples remained, including 12 technically duplicated pairs Supplementary Table S1. EnsembleCNV a identifies and eliminates batch effects at raw data level; b assembles individual CNV calls into CNV regions CNVRs from multiple existing callers with complementary strengths by a heuristic algorithm; c re-genotypes each CNVR with local likelihood model adjusted by global information across multiple CNVRs; d refines CNVR boundaries by local correlation structure in copy number intensities; e provides direct CNV genotyping accompanied with confidence score, directly accessible for downstream quality control and association analysis.

There were CNVs defined as singleton events i. We previously showed an enrichment of rare, exonic deletion CNVs in a ipatttern of RDD, with a low frequency of such variants in a screened control sample The sponsors of the study had no role in the study design, data collection, data analysis, data interpretation, or writing of the report; however, MRB was employed by GlaxoSmithKline when the research was performed.

Contribution of copy number variants to schizophrenia from a genome-wide study of 41,321 subjects

Comprehensive assessment of array-based platforms and calling algorithms for detection of copy number variants. Citing articles via Web of Science 1. Eysenck Personality Questionnaire data were available in samples.

We found, when accurately typed, CNVs are overwhelmingly inherited Dosage-dependent phenotypes in models of 16p While the CMH test does not account for more subtle biases that could drive false positive signals, it is robust to signals driven by a single platform and allows for each CNV carrier to be treated equally.

Accessed February, 2 Lastly, in order to control for case-control differences in CNV ascertainment due to data quality we sought to identify data quality metrics that were confounded with case status.

CNV losses and gains at the 22q Nonetheless, this study found a significant enrichment of sex chromosome abnormalities among patients in psychiatric hospitals at the time compared with a control population. Smears from the oral mucosa in the detection of chromosomal ipattfrn. Rare chromosomal deletions and duplications increase risk of schizophrenia.

Proper ways to handle batch effects are prerequisite to produce high-quality CNV signals.

We analyzed samples from our cases and screened control samples on the comparative genomic hybridization array. Oxford Ipaattern Press is a department of the University of Oxford. In order to ensure the robustness of the analysis, burden and gene-set analyses included potential confounding variables as covariates in a logistic regression framework.

No significant association was found between global rare CNV burden per sample and age of onset of disorder. This may be a relevant finding because deletion CNVs, with concomitant loss of function, are expected to be more deleterious than duplications. CNVs were mapped to genes if they overlapped one or more exons. When an individual receives two identical copies of a chromosome, or part of a chromosome, from one parent, it is known as UPD.

Due to the number of tests run at breakpoint level association, we ippattern a step-wise logistic regression approach to allow for the inclusion of covariates in our case-control association, which we term the SCZ residual phenotype. Papadimitriou54 Elena Parkhomenko8 Michele T.

No evidence for an involvement of copy number variation in ABCA13 in schizophrenia, bipolar disorder, or major depressive disorder.
