CVID affects approximately 1 in 10,000 to 1 in 50,000 people worldwide with substantial heterogeneity in disease severity, including asymptomatic individuals designated as hypogammaglobulinemia of undetermined significance (HGUS). As expected of humoral immunodeficiency, the molecular causes of CVID primarily affect the maturation, activation, or survival of B cells and plasma cells. In this retrospective analysis, we defined a cohort of 21 patients with a primary CVID or HGUS diagnosis in the v7 release of the <jats:italic>All of Us<\/jats:italic> Research Program database and performed gene annotation and variant effect prediction. Our analysis identified both known disease-causing variants and rare genetic variants overlapping with other immunodeficiency syndromes.<\/jats:p>","DOI":"10.3389\/fgene.2024.1409754","type":"journal-article","created":{"date-parts":[[2024,10,2]],"date-time":"2024-10-02T04:40:24Z","timestamp":1727844024000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Analysis of rare genetic variants in All of Us cohort patients with common variable immunodeficiency"],"prefix":"10.3389","volume":"15","author":[{"given":"Troy","family":"von Beck","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meera","family":"Patel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niraj C.","family":"Patel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joshy","family":"Jacob","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,10,2]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"656","DOI":"10.1182\/blood.2019000929","article-title":"Current genetic landscape in common variable immune deficiency","volume":"135","author":"Abolhassani","year":"2020","journal-title":"Blood"},{"key":"B2","unstructured":"Researcher workbench2024"},{"key":"B3","doi-asserted-by":"publisher","first-page":"203","DOI":"10.1111\/cei.12178","article-title":"New diagnostic criteria for common variable immune deficiency (CVID), which may assist with decisions to treat with intravenous or subcutaneous immunoglobulin","volume":"174","author":"Ameratunga","year":"2013","journal-title":"Clin.
