Cure8 research brief
Primary immunodeficiencies like atypical X‑SCID can present as chronic IBD‑like disease, especially when symptoms begin in childhood — so genetic testing may change diagnosis and care for some patients with early‑onset or atypical IBD.
Pediatric and adult patients with early‑onset or treatment‑resistant IBD, caregivers, gastroenterologists, and immunologists.
This report describes a 24‑year‑old male with lifelong immune dysregulation and early‑onset Crohn’s‑like intestinal inflammation who was found to have a hemizygous intronic IL2RG variant causing aberrant splicing.
Genetic and RNA testing supported a diagnosis of atypical (hypomorphic) X‑linked severe combined immunodeficiency (X‑SCID), and the case authors note that his intestinal disease had been managed with azathioprine. The case highlights that primary immunodeficiency can present as chronic IBD‑like enterocolitis, especially when symptoms begin in childhood.
Comprehensive genome sequencing with transcript analysis was key to finding the splice defect; recognizing such atypical presentations can affect monitoring, prognosis, and discussions about definitive therapies (for example, immune‑reconstituting treatments), though the article is a single case report and does not provide treatment outcomes.
If you have early‑onset, severe, or treatment‑resistant IBD with recurrent infections or other signs of immune dysfunction, this paper supports considering genetic evaluation and specialist referral. It does not provide new general treatment recommendations.
Single‑patient case report; diagnosis required genome sequencing and RNA splicing analysis. Does not report treatment outcomes or establish prevalence.

This trial is testing whether adding vedolizumab after autologous stem cell transplant can improve remission rates for people with severe Crohn's disease that has failed multiple therapies.
Because it describes a severe new Crohn’s disease case temporally linked to COVID‑19, patients and clinicians should be aware that persistent or worsening GI symptoms after SARS‑CoV‑2 infection may merit investigation;...
Because intestinal lymphoma can closely mimic Crohn’s disease, recognizing red flags (severe malabsorption, proximal small-bowel involvement, monoclonal gammopathy, poor response to IBD therapy) can change diagnosis and...
