Functional study of those GWAS-identified loci might represent an important step toward understanding AUD pathophysiology. We found that genetic loci which are splicing quantitative trait loci (sQTLs) for the\n                  <jats:italic>fibronectin III domain containing 4<\/jats:italic>\n                  (\n                  <jats:italic>FNDC4<\/jats:italic>\n                  ) gene in the brain were identified by GWAS for both AUD drug treatment outcomes and AUD risk. However, FNDC4 function in the brain and how it might contribute to AUD pathophysiology remain unknown. In the present study, we characterized GWAS locus-associated\n                  <jats:italic>FNDC4<\/jats:italic>\n                  splice isoforms, studies which suggested that FNDC4 alternative splicing results in loss-of-function for FNDC4. We also investigated\n                  <jats:italic>FNDC4<\/jats:italic>\n                  function using CRISPR\/cas9 gene editing, and the creation of human induced pluripotent stem cell (iPSC)-derived neural organoids joined with single-nucleus RNA sequencing. We observed that knock-out (KO) of\n                  <jats:italic>FNDC4<\/jats:italic>\n                  resulted in a striking shift in the relative proportions of glutamatergic and GABAergic neurons in iPSC-derived neural organoids, suggesting a possible important role for FNDC4 in neurogenesis. We also explored potential mechanism(s) of\n                  <jats:italic>FNDC4<\/jats:italic>\n                  -dependent neurogenesis with results that suggested a role for FNDC4 in mediating neural cell-cell interaction. In summary, this series of experiments indicates that FNDC4 plays a role in regulating cerebral cortical neurogenesis in the brain. This regulation may contribute to the response to AUD pharmacotherapy as well as the effects of alcohol on the brain.\n                <\/jats:p>","DOI":"10.1101\/2025.05.15.654319","type":"posted-content","created":{"date-parts":[[2025,5,17]],"date-time":"2025-05-17T03:40:13Z","timestamp":1747453213000},"source":"Crossref","is-referenced-by-count":0,"title":["Alcohol Use Disorder Associated Gene\n                  <i>FNDC4<\/i>\n                  Alters Glutamatergic and GABAergic Neurogenesis"],"prefix":"10.64898","author":[{"given":"Xiujuan","family":"Zhu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"August J.","family":"John","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sooan","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Enci","family":"Ding","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ateka","family":"Saleh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Irene","family":"Mar\u00edn-Go\u00f1i","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abedalrahman","family":"Jomaa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huanyao","family":"Gao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ching Man","family":"Wai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Irene","family":"Moon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brandon J.","family":"Coombes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tony M.","family":"Kerr","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8994-2592","authenticated-orcid":false,"given":"Nobuyoshi","family":"Suto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liewei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6997-4215","authenticated-orcid":false,"given":"Mark A.","family":"Frye","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9350-4440","authenticated-orcid":false,"given":"Joanna M.","family":"Biernacka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9552-6130","authenticated-orcid":false,"given":"Victor M.","family":"Karpyak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5957-5472","authenticated-orcid":false,"given":"Hu","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4911-7985","authenticated-orcid":false,"given":"Richard M.","family":"Weinshilboum","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1065-246X","authenticated-orcid":false,"given":"Duan","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","reference":[{"key":"2025052009250447000_2025.05.15.654319v1.1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(19)31775-1"},{"key":"2025052009250447000_2025.05.15.654319v1.2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra2306511"},{"key":"2025052009250447000_2025.05.15.654319v1.3","doi-asserted-by":"publisher","DOI":"10.1016\/S2215-0366(16)00104-8"},{"key":"2025052009250447000_2025.05.15.654319v1.4","doi-asserted-by":"publisher","DOI":"10.1038\/nrgastro.2013.86"},{"key":"2025052009250447000_2025.05.15.654319v1.5","doi-asserted-by":"crossref","unstructured":"Zhou, H. & Gelernter, J .
