Hitherto, only 10 patients were reported worldwide. Here, we report a boy who presented with recurrent high fever, oral ulcers, abdominal pain, and hematochezia for over 2\u00a0weeks. His serum inflammatory markers were elevated, and colonoscopy showed multiple colon ulcers and terminal ileum ulcers which resemble colitis caused by inflammatory bowel disease. A novel heterozygous variant c.934G&amp;gt;T(p.Glu312Ter) in the <jats:italic>MSN<\/jats:italic> gene was identified using whole exome sequencing (WES) and trio analysis. Intestinal ulcers were almost healed after inducing therapy with steroids and maintenance treatment of anti-TNF\u03b1 therapy. We summarized the genotype and phenotype of reported X-MAID patients and presented the patient\u2019s unique phenotype in this study. This study also expanded the spectrum of <jats:italic>MSN<\/jats:italic> mutation-caused immunodeficiency.<\/jats:p>","DOI":"10.3389\/fgene.2022.873635","type":"journal-article","created":{"date-parts":[[2022,6,9]],"date-time":"2022-06-09T07:14:26Z","timestamp":1654758866000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":15,"title":["A Novel Variant of X-Linked Moesin Gene in a Boy With Inflammatory Bowel Disease Like Disease-A Case Report"],"prefix":"10.3389","volume":"13","author":[{"given":"Youhong","family":"Fang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youyou","family":"Luo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,6,9]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"91","DOI":"10.1093\/ecco-jcc\/jjab124","article-title":"Primary Hypogammaglobulinaemia with Inflammatory Bowel Disease-like Features: An ECCO CONFER Multicentre Case Series","volume":"16","author":"Albshesh","year":"2021","journal-title":"J.
