Abstract Background and Objectives: Chronic widespread musculoskeletal pain (CWP) is a symptom of fibromyalgia and a complex trait with poorly understood pathogenesis. CWP is heritable (48- 54%), but its genetic architecture is unknown and candidate gene studies have produced inconsistent results. We conducted a genome-wide association study to get insight into the genetic background of CWP. Methods: Northern Europeans from UK Biobank comprising 6,914 cases reporting pain all over the body lasting more than 3 months and 242,929 controls were studied. Replication of three lead genome-wide significant single nucleotide polymorphisms (SNPs) was attempted in 6 independent European cohorts (N=43,080; cases=14,177). Genetic correlations with risk factors, tissue specificity, and colocalization were examined. Results: Three genome-wide significant loci were identified (rs1491985, rs10490825, rs165599) residing within the genes RNF123, ATP2C1, and COMT. The RNF123 locus was replicated (meta-analysis p=0.0002), the ATP2C1 locus showed suggestive association (p=0.0227), and the COMT locus was not replicated. Partial genetic correlation between CWP and depressive symptoms, body mass index, age of first birth, and years of schooling were identified. Tissue specificity and colocalization analysis highlight the relevance of skeletal muscle in CWP. Conclusions: We report a novel association of RNF123 locus with CWP and suggest a role of ATP2C1, consistent with a role of calcium regulation in CWP. The association to COMT, one of the most studied genes in chronic pain field, was not confirmed in the replication analysis. Keywords: Chronic widespread pain, fibromyalgia, genome-wide association study, twin, RNF123. 4 medRxiv preprint doi: https://doi.org/10.1101/2020.11.30.20241000; this version posted December 3, 2020.

Key messages What is already known about this subject? • Chronic widespread musculoskeletal pain (CWP) is a primary diagnostic feature of fibromyalgia. • CWP is moderately heritable, but precise genes involved in the pathogenesis of CWP are yet to be identified. What does this study add? • This is the largest genetic study conducted on CWP to date and identified novel genetic risk loci (RNF123 and ATP2C1). • The genetic signal points to peripheral pain mechanisms in CWP, and shows genetic correlation with other traits, including BMI and depression. How might this impact on clinical practice or future developments? • The findings add to etiological basis of CWP. 5 medRxiv preprint doi: https://doi.org/10.1101/2020.11.30.20241000; this version posted December 3, 2020.

  • The Role and Robustness of the Gini Coefficient As an Unbiased Tool For
    www.nature.com/scientificreports OPEN The role and robustness of the Gini coefcient as an unbiased tool for the selection of Gini genes for normalising expression profling data Marina Wright Muelas 1*, Farah Mughal1, Steve O’Hagan2,3, Philip J. Day3,4* & Douglas B. Kell 1,5* We recently introduced the Gini coefcient (GC) for assessing the expression variation of a particular gene in a dataset, as a means of selecting improved reference genes over the cohort (‘housekeeping genes’) typically used for normalisation in expression profling studies. Those genes (transcripts) that we determined to be useable as reference genes difered greatly from previous suggestions based on hypothesis-driven approaches. A limitation of this initial study is that a single (albeit large) dataset was employed for both tissues and cell lines. We here extend this analysis to encompass seven other large datasets. Although their absolute values difer a little, the Gini values and median expression levels of the various genes are well correlated with each other between the various cell line datasets, implying that our original choice of the more ubiquitously expressed low-Gini-coefcient genes was indeed sound. In tissues, the Gini values and median expression levels of genes showed a greater variation, with the GC of genes changing with the number and types of tissues in the data sets. In all data sets, regardless of whether this was derived from tissues or cell lines, we also show that the GC is a robust measure of gene expression stability. Using the GC as a measure of expression stability we illustrate its utility to fnd tissue- and cell line-optimised housekeeping genes without any prior bias, that again include only a small number of previously reported housekeeping genes.

O’Donovan,1 and Nick Craddock1 We present a method for testing overrepresentation of biological pathways, indexed by gene-ontology terms, in lists of significant SNPs from genome-wide association studies. This method corrects for linkage disequilibrium between SNPs, variable gene size, and multiple testing of nonindependent pathways. The method was applied to the Wellcome Trust Case-Control Consortium Crohn disease (CD) data set. At a general level, the biological basis of CD is relatively well known for a complex genetic trait, and it thus acted as a test of the method. The method, known as ALIGATOR (Association LIst Go AnnoTatOR), successfully detected biological pathways implicated in CD. The method was also applied to a meta-analysis of bipolar disorder, and it implicated the modulation of transcription and cellular activity, including that which occurs via hormonal action, as an important player in pathogenesis.

  • REPORT Familial Chilblain Lupus, a Monogenic Form of Cutaneous Lupus Erythematosus, Maps to Chromosome 3P
    REPORT Familial Chilblain Lupus, a Monogenic Form of Cutaneous Lupus Erythematosus, Maps to Chromosome 3p Min Ae Lee-Kirsch, Maolian Gong, Herbert Schulz, Franz Ru¨schendorf, Annette Stein, Christiane Pfeiffer, Annalisa Ballarini, Manfred Gahr, Norbert Hubner, and Maja Linne´ Systemic lupus erythematosus is a prototypic autoimmune disease. Apart from rare monogenic deficiencies of complement factors, where lupuslike disease may occur in association with other autoimmune diseases or high susceptibility to bacterial infections, its etiology is multifactorial in nature. Cutaneous findings are a hallmark of the disease and manifest either alone or in association with internal-organ disease. We describe a novel genodermatosis characterized by painful bluish- red inflammatory papular or nodular lesions in acral locations such as fingers, toes, nose, cheeks, and ears. The lesions sometimes appear plaquelike and tend to ulcerate. Manifestation usually begins in early childhood and is precipitated by cold and wet exposure. Apart from arthralgias, there is no evidence for internal-organ disease or an increased sus- ceptibility to infection. Histological findings include a deep inflammatory infiltrate with perivascular distribution and granular deposits of immunoglobulins and complement along the basement membrane. Some affected individuals show antinuclear antibodies or immune complex formation, whereas cryoglobulins or cold agglutinins are absent. Thus, the findings are consistent with chilblain lupus, a rare form of cutaneous lupus erythematosus. Investigation of a large German kindred with 18 affected members suggests a highly penetrant trait with autosomal dominant inheritance. By single-nucleotide-polymorphism–based genomewide linkage analysis, the locus was mapped to chromosome 3p. Hap- lotype analysis defined the locus to a 13.8-cM interval with a LOD score of 5.04.

This data provides an opportunity for deriving shared and tissue-specific gene regulatory networks on the basis of co-expression between genes. However, a small number of samples are available for a majority of the tissues, and therefore statistical inference of networks in this setting is highly underpowered. To address this problem, we infer tissue-specific gene co-expression networks for 35 tissues in the GTEx dataset using a novel algorithm, GNAT, that uses a hierarchy of tissues to share data between related tissues. We show that this transfer learning approach increases the accuracy with which networks are learned. Analysis of these networks reveals that tissue-specific transcription factors are hubs that preferentially connect to genes with tissue-specific functions.

  • Long Non-Coding RNA-Dependent Mechanism to Regulate Heme Biosynthesis and Erythrocyte Development
    ARTICLE DOI: 10.1038/s41467-018-06883-x OPEN Long non-coding RNA-dependent mechanism to regulate heme biosynthesis and erythrocyte development Jinhua Liu1,2, Yapu Li1,2, Jingyuan Tong1,2, Jie Gao1,2, Qing Guo1,2, Lingling Zhang3, Bingrui Wang1,2, Hui Zhao3, Hongtao Wang1,2, Erlie Jiang1,2, Ryo Kurita4, Yukio Nakamura5, Osamu Tanabe6, James Douglas Engel7, Emery H. Bresnick8, Jiaxi Zhou1,2 & Lihong Shi1,2 1234567890():,; In addition to serving as a prosthetic group for enzymes and a hemoglobin structural com- ponent, heme is a crucial homeostatic regulator of erythroid cell development and function. While lncRNAs modulate diverse physiological and pathological cellular processes, their involvement in heme-dependent mechanisms is largely unexplored. In this study, we eluci- dated a lncRNA (UCA1)-mediated mechanism that regulates heme metabolism in human erythroid cells. We discovered that UCA1 expression is dynamically regulated during human erythroid maturation, with a maximal expression in proerythroblasts. UCA1 depletion pre- dominantly impairs heme biosynthesis and arrests erythroid differentiation at the proery- throblast stage. Mechanistic analysis revealed that UCA1 physically interacts with the RNA- binding protein PTBP1, and UCA1 functions as an RNA scaffold to recruit PTBP1 to ALAS2 mRNA, which stabilizes ALAS2 mRNA. These results define a lncRNA-mediated post- transcriptional mechanism that provides a new dimension into how the fundamental heme biosynthetic process is regulated as a determinant of erythrocyte development. 1 State Key Laboratory of Experimental Hematology, Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College, Tianjin 300020, China. 2 Center for Stem Cell Medicine, Chinese Academy of Medical Sciences, Beijing 100730, China.
