Genetic heritability studies of acne in twin cohorts have estimated that the heritability for acne is 80%. Previous genome-wide association studies (GWAS) have identified 50 genetic\n                  <jats:italic>loci<\/jats:italic>\n                  associated with increased risk of developing acne when compared to healthy individuals. However only a few studies have investigated genetic association with disease severity. GWAS of disease progression may provide a more effective approach to unveil potential disease modifying therapeutic targets.\n                <\/jats:p>\n                <jats:p>Here, we performed a multi-ethnic GWAS analysis to capture disease severity in acne patients by using individuals with normal acne as a control. Our cohort consists of a total of 2,956 participants, including 290 severe acne cases and 930 normal acne controls from FinnGen, and 522 cases and 1,214 controls from BioVU. We also performed mendelian randomization (MR), colocalization analyses and transcriptome-wide association study (TWAS) to identify putative causal genes. Lastly, we performed gene-set enrichment analysis using MAGMA to implicate biological pathways that drive disease severity in Acne.<\/jats:p>\n                <jats:p>\n                  We identified two new loci associated with acne severity at the genome-wide significance level, six novel associated genes by MR, colocalization and TWAS analyses, including genes\n                  <jats:italic>CDC7, SLC7A1, ADAM23, TTLL10, CDK20<\/jats:italic>\n                  and\n                  <jats:italic>DNAJA4<\/jats:italic>\n                  , and 5 novel pathways by MAGMA analyses. Our study suggests that the etiologies of acne susceptibility and severity have limited overlap, with only 26% of known acne risk loci presenting nominal association with acne severity and none of the novel severity associated genes reported as associated with acne risk in previous GWAS.\n                <\/jats:p>","DOI":"10.1101\/2023.11.13.23298473","type":"posted-content","created":{"date-parts":[[2023,11,14]],"date-time":"2023-11-14T17:35:29Z","timestamp":1699983329000},"source":"Crossref","is-referenced-by-count":1,"title":["Genome-wide association study analysis of disease severity in Acne reveals novel biological insights"],"prefix":"10.64898","author":[{"given":"Zhaohui","family":"Du","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tejaswi","family":"Iyyanki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1010-2268","authenticated-orcid":false,"given":"Samuel","family":"Lessard","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Chao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"FinnGen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Asbrand","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dany","family":"Nassar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katherine","family":"Klinger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emanuele","family":"de Rinaldis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shameer","family":"Khader","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cl\u00e9ment","family":"Chatelain","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","reference":[{"key":"2023111611050725000_2023.11.13.23298473v1.1","doi-asserted-by":"crossref","first-page":"361","DOI":"10.1016\/S0140-6736(11)60321-8","article-title":"Acne vulgaris","volume":"379","year":"2012","journal-title":"The Lancet"},{"key":"2023111611050725000_2023.11.13.23298473v1.2","doi-asserted-by":"crossref","first-page":"86","DOI":"10.1111\/j.1529-8019.2008.00175.x","article-title":"New and emerging treatments in dermatology: acne","volume":"21","year":"2008","journal-title":"Dermatol.
