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. -

METHODS We assembled data from 19 newly identified and all 18 previously published individuals with CYFIP2 variants. By structural modeling and investigation of WAVE-regulatory complex (WRC)-mediated actin polymerization in six patient fibroblast lines we assessed the impact of CYFIP2 variants on the WRC. RESULTS Sixteenof 19 individuals harbor two previously described and 11 novel (likely) disease-associated missense variants. We report p.Asp724 as second mutational hotspot (4/19 cases). Genotype-phenotype correlation con- firms a consistently severe phenotype in p.Arg87 patients but a more variable phenotype inp.Asp724 and other substitutions. Three individuals with milder phenotypes carry putative loss-of-function vari- ants, which remain of unclear pathogenicity. Structural modeling predicted missense variants to disturb interactions within the WRC or impair CYFIP2 stability. Consistent with its role in WRC-mediated actin polymerization we substantiate aberrant regulation of the actin cytoskeleton in patient fibroblasts. CONCLUSION Our study expands the clinical and molecular spectrum of CYFIP2-related neurodevel- opmental disorder and provides evidence for aberrant WRC-mediated actin dynamics as contributing cellular pathomechanism. -
Supplemental Information
Supplemental information Dissection of the genomic structure of the miR-183/96/182 gene. Previously, we showed that the miR-183/96/182 cluster is an intergenic miRNA cluster, located in a ~60-kb interval between the genes encoding nuclear respiratory factor-1 (Nrf1) and ubiquitin-conjugating enzyme E2H (Ube2h) on mouse chr6qA3.3 (1). To start to uncover the genomic structure of the miR- 183/96/182 gene, we first studied genomic features around miR-183/96/182 in the UCSC genome browser (http://genome.UCSC.edu/), and identified two CpG islands 3.4-6.5 kb 5’ of pre-miR-183, the most 5’ miRNA of the cluster (Fig. 1A; Fig. S1 and Seq. S1). A cDNA clone, AK044220, located at 3.2-4.6 kb 5’ to pre-miR-183, encompasses the second CpG island (Fig. 1A; Fig. S1). We hypothesized that this cDNA clone was derived from 5’ exon(s) of the primary transcript of the miR-183/96/182 gene, as CpG islands are often associated with promoters (2). Supporting this hypothesis, multiple expressed sequences detected by gene-trap clones, including clone D016D06 (3, 4), were co-localized with the cDNA clone AK044220 (Fig. 1A; Fig. S1). Clone D016D06, deposited by the German GeneTrap Consortium (GGTC) (http://tikus.gsf.de) (3, 4), was derived from insertion of a retroviral construct, rFlpROSAβgeo in 129S2 ES cells (Fig. 1A and C). The rFlpROSAβgeo construct carries a promoterless reporter gene, the β−geo cassette - an in-frame fusion of the β-galactosidase and neomycin resistance (Neor) gene (5), with a splicing acceptor (SA) immediately upstream, and a polyA signal downstream of the β−geo cassette (Fig. -

Integrative Genomics Analyses Reveal Molecularly Distinct Subgroups of B-Cell Chronic Lymphocytic Leukemia Patients with 13Q14 Deletion

The exact mechanisms involved in this lesion have not yet been fully elucidated because of its heterogeneity and the imprecise knowledge of the implicated genes. This study was addressed to further contribute to the molecular definition of this lesion in CLL. Experimental Design: We applied single-nucleotide polymorphism (SNP)-array technology and gene expression profiling data to investigate the 13q14 deletion occurring in a panel of 100 untreated, early-stage (Binet A) patients representative of the major genetics, molecular, and biological features of the disease. Results: Concordantly with FISH analysis, SNP arrays identified 44 patients with del(13)(q14) including 11 cases with a biallelic deletion. The shorter monoallelic deletion was 635-kb long. The loss of the miR-15a/16-1 cluster occurred in all del(13)(q14) cases except in 2 patients with a monoallelic deletion, who retained both copies. MiR-15a/16 expression was significantly downregulated only in patients with the biallelic loss of the miRNA cluster compared to 13q normal cases. -

Comparative RNA Editing in Autistic and Neurotypical Cerebella
Molecular Psychiatry (2013) 18, 1041–1048 & 2013 Macmillan Publishers Limited All rights reserved 1359-4184/13 www.nature.com/mp ORIGINAL ARTICLE Comparative RNA editing in autistic and neurotypical cerebella A Eran1,2,JBLi3, K Vatalaro2, J McCarthy2, F Rahimov2,4, C Collins2,4, K Markianos2,5, DM Margulies5,6,7, EN Brown1,8,9, SE Calvo10, IS Kohane1,5,7 and LM Kunkel2,4,5,11 Adenosine-to-inosine (A-to-I) RNA editing is a neurodevelopmentally regulated epigenetic modification shown to modulate complex behavior in animals. Little is known about human A-to-I editing, but it is thought to constitute one of many molecular mechanisms connecting environmental stimuli and behavioral outputs. Thus, comprehensive exploration of A-to-I RNA editing in human brains may shed light on gene–environment interactions underlying complex behavior in health and disease. Synaptic function is a main target of A-to-I editing, which can selectively recode key amino acids in synaptic genes, directly altering synaptic strength and duration in response to environmental signals. Here, we performed a high-resolution survey of synaptic A-to-I RNA editing in a human population, and examined how it varies in autism, a neurodevelopmental disorder in which synaptic abnormalities are a common finding. Using ultra-deep (41000 Â ) sequencing, we quantified the levels of A-to-I editing of 10 synaptic genes in postmortem cerebella from 14 neurotypical and 11 autistic individuals. A high dynamic range of editing levels was detected across individuals and editing sites, from 99.6% to below detection limits. In most sites, the extreme ends of the population editing distributions were individuals with autism. -
