Abstract

CARMIL2 deficiency is a rarely occurring, autosomal recessive immunodeficiency disease, manifested as an impairment in CD28-mediated T-cell costimulation, actin cytoskeleton dysregulation and a broad immunological disturbance across T, B and NK cell lineages.
It has been strongly associated with an early onset of inflammatory bowel disease-like enteropathies, recurrent infections, dermatitis and eczema. While gastrointestinal involvement is well documented, celiac disease has not yet been reported in this context.
We present a case of a 23-year-old Saudi male with genetically confirmed CARMIL2 deficiency who developed true celiac disease demonstrated through a comprehensive gastrointestinal evaluation, with an extensive diagnostic workup that included upper endoscopy with duodenal biopsies, histopathological examination and celiac serologies (tTG IgA, tTG IgG and DGP IgA/IgG).
