We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated.

Our recently launched Version 4 has a revamped infrastructure facilitating faster data updates, better-targeted data queries, and friendlier user experience. It also provides a stronger foundation for the GeneCards suite of companion databases and analysis tools. Improved data unification includes gene-disease links via MalaCards and merged biological pathways via PathCards, as well as drug information and proteome expression. VarElect, another suite member, is a phenotype prioritizer for next-generation sequencing, leveraging the GeneCards and MalaCards knowledgebase. It au- tomatically infers direct and indirect scored associations between hundreds or even thousands of variant-containing genes and disease phenotype terms.

Multiple SNP-sets Analysis for Genome-wide Association Studies through Bayesian Latent Variable Selection Zhaohua Lu, Hongtu Zhu, Rebecca C Knickmeyer, Patrick F. Sullivan, Williams N. Stephanie, and Fei Zou for the Alzheimer’s Disease Neuroimaging Initiative* Departments of Biostatistics, Psychiatry, and Genetics and Biomedical Research Imaging Center, University of North Carolina at Chapel Hill, Chapel Hill, NC 27599, USA Abstract The power of genome-wide association studies (GWAS) for mapping complex traits with single SNP analysis may be undermined by modest SNP effect sizes, unobserved causal SNPs, correlation among adjacent SNPs, and SNP-SNP interactions. Alternative approaches for testing the association between a single SNP-set and individual phenotypes have been shown to be promising for improving the power of GWAS. We propose a Bayesian latent variable selection (BLVS) method to simultaneously model the joint association mapping between a large number of SNP-sets and complex traits. Compared to single SNP-set analysis, such joint association mapping not only accounts for the correlation among SNP-sets, but also is capable of detecting causal SNP- sets that are marginally uncorrelated with traits. The spike-slab prior assigned to the effects of SNP-sets can greatly reduce the dimension of effective SNP-sets, while speeding up computation. An efficient MCMC algorithm is developed. Simulations demonstrate that BLVS outperforms several competing variable selection methods in some important scenarios.

Spangler9, Robert L. Weaber10, Dorian J. Garrick2,11 and Jeremy F. Taylor4* Abstract Background: Single nucleotide polymorphism (SNP) arrays for domestic cattle have catalyzed the identification of genetic markers associated with complex traits for inclusion in modern breeding and selection programs. Using actual and imputed Illumina 778K genotypes for 3887 U.S. beef cattle from 3 populations (Angus, Hereford, SimAngus), we performed genome-wide association analyses for feed efficiency and growth traits including average daily gain (ADG), dry matter intake (DMI), mid-test metabolic weight (MMWT), and residual feed intake (RFI), with marker-based heritability estimates produced for all traits and populations. Results: Moderate and/or large-effect QTL were detected for all traits in all populations, as jointly defined by the estimated proportion of variance explained (PVE) by marker effects (PVE ≥ 1.0%) and a nominal P-value threshold (P ≤ 5e-05). Lead SNPs with PVE ≥ 2.0% were considered putative evidence of large-effect QTL (n = 52), whereas those with PVE ≥ 1.0% but < 2.0% were considered putative evidence for moderate-effect QTL (n = 35).

  • Early-Onset Diabetes Mellitus in a Patient with a Chromosome 13Q34qter Microdeletion Including IRS2
    ISSN 2472-1972 Early-Onset Diabetes Mellitus in a Patient With a Chromosome 13q34qter Microdeletion Including IRS2 Naru Babaya,1 Shinsuke Noso,1 Yoshihisa Hiromine,1 Hiroyuki Ito,1 Yasunori Taketomo,1 Toshiyuki Yamamoto,2,3 Yumiko Kawabata,1 and Hiroshi Ikegami1 1Department of Endocrinology, Metabolism and Diabetes, Kindai University Faculty of Medicine, Osaka- sayama, Osaka 589-8511, Japan; 2Institute of Medical Genetics, Tokyo Women’s Medical University, Shinjuku-ward, Tokyo 162-8666, Japan; and 3Tokyo Women’s Medical University Institute for Integrated Medical Sciences, Shinjuku-ward, Tokyo 162-8666, Japan ORCiD numbers: 0000-0003-2466-1228 (N. Babaya). Diabetes mellitus is a multifactorial disease caused by a complex interaction of environmental and genetic factors. Some diabetes mellitus cases, however, are caused by a limited number of mutant genes. Chromosome 13q deletion syndrome, an extremely rare genetic disorder, is caused by structural and functional monosomy of the 13q chromosomal region. We report the case of a 38-year-old Japanese man with Chr13q deletion (a mosaic pattern with heterozygous ring Chr13q) who developed diabetes mellitus. Early-onset diabetes mellitus developed in this patient because of insulin resistance and a lack of adequate insulin secretion. Microarray analysis identified a 4.8-Mb deletion of distal Chr13q, leading to a copy number loss of 40 genes. Among those genes, the insulin receptor substrate 2 gene (IRS2) was the most likely causative candidate for the development of diabetes mellitus in this patient, based on the model of IRS2 knockout mice, which have abnormal glucose and insulin homeostasis closely resembling the human diabetes phenotype.

  • RNA-Sequencing Analysis of Shell Gland Shows Differences in Gene Expression Profile at Two Time-Points of Eggshell Formation In
    Khan et al. BMC Genomics (2019) 20:89 https://doi.org/10.1186/s12864-019-5460-4 RESEARCHARTICLE Open Access RNA-sequencing analysis of shell gland shows differences in gene expression profile at two time-points of eggshell formation in laying chickens Samiullah Khan1,2, Shu-Biao Wu1* and Juliet Roberts1 Abstract Background: Eggshell formation takes place in the shell gland of the oviduct of laying hens. The eggshell is rich in calcium and various glycoproteins synthesised in the shell gland. Although studies have identified genes involved in eggshell formation, little is known about the regulation of genes in the shell gland particularly in a temporal manner. The current study investigated the global gene expression profile of the shell gland of laying hens at different time-points of eggshell formation using RNA-Sequencing (RNA-Seq) analysis. Results: Gene expression profiles of the shell gland tissue at 5 and 15 h time-points were clearly distinct from each other. Out of the 14,334 genes assessed for differential expression in the shell gland tissue, 278 genes were significantly down-regulated (log2 fold change > 1.5; FDR < 0.05) and 413 genes were significantly up-regulated at 15 h relative to the 5 h time-point of eggshell formation. The down-regulated genes annotated to Gene Ontology (GO) terms showed anion transport, synaptic vesicle localisation, organic anion transport, secretion and signal release as the five most enriched terms. The up-regulated gene annotation showed regulation of phospholipase activities, alanine transport, transmembrane receptor protein tyrosine kinase signalling pathway, regulation of blood vessels diameter and 3, 5-cyclic nucleotide phosphodiesterase activity as the five most enriched GO terms.

  • Investigation of the Genetic Cause of Hearing Loss In
    INVESTIGATION OF THE GENETIC CAUSE OF HEARING LOSS IN NEWFOUNDLAND FAMILIES by © Cindy Penney Thesis submitted to the School of Graduate Studies in partial fulfillment of the requirements for the degree of Master of Science Medicine Human Genetics/Faculty of Medicine Memorial University of Newfoundland May 2018 St. John’s Newfoundland and Labrador Abstract The purpose of this study was to determine the genetic cause of hearing loss in a seven-generation Newfoundland family. Twenty-nine family members were recruited segregating autosomal dominant hearing loss. Genome-wide SNP genotyping and linkage analysis showed significant linkage (LOD=4.77) to chromosome 13q34. The region contained 26 genes and a known deafness locus (DFNA33). Exome sequencing identified 13 variants of interest within the linked region, but only 3 co-segregated with hearing loss: F10 c.865+26C>T, ADPRHL1 c.380-17C>A and c.380-16T>G. All three were absent from 81 population controls, yet the ADPRHL1 c.380-17C>A and c.380-16T>G were identified in two other probands with hearing loss. All three were predicted to affect splicing of nearby exons, however cDNA analysis of ADPRHL1 showed no effect. F10 c.865+26C>T, ADPRHL1 c.380-17C>A and c.380-16T>G are rare, co- segregate with hearing loss, and are possibly pathogenic. Conversely, they may help form a disease haplotype and exist in linkage disequilibrium with the causal mutation. However, the putative ADPRHL1 variants have been found in multiple families with hearing loss and further investigations are necessary to elucidate their effect. ii Acknowledgements My thesis project has been an exciting learning experience.

Background: Myasthenia gravis (MG) is a group of autoimmune disease which could be accompanied by thymoma. Many differences have been observed between thymoma-associated MG (TAMG) and non-MG thymoma (NMG). However, the molecular difference between them remained unknown. This study aimed to explore the differentially expressed genes (DEGs) between the two categories and to elucidate the possible pathogenesis of TAMG further. Methods: DEGs were calculated using the RNA-Sequencing data from 11 TAMG and 10 NMG in The Cancer Genome Atlas (TCGA) database.

ABSTRACT Despite many genes associated with human diseases have been identified, disease mechanisms often remain elusive due to the lack of understanding how disease genes are connected functionally at pathways level. Within biological networks, disease genes likely map to modules whose identification facilitates etiology studies but remains challenging. We describe a systematic approach to identify disease-associated gene modules.
