Case Report: IL2RA (CD25) deficiency: first reported cases in Morocco.

ABSTRACT: CD25, the α-chain of the interleukin-2 receptor (IL2RA), is a key component of the IL-2 pathway and is essential for the development and stability of regulatory T cells. Loss-of-function variants in IL2RA cause a very rare autosomal recessive disorder marked by early-onset autoimmunity and recurrent infections with an IPEX-like presentation. We report the first two molecularly confirmed cases of IL2RA (CD25) deficiency in Morocco, each carrying a distinct homozygous mutation. Both patients were born to first-cousin parents and presented in early childhood with recurrent respiratory and gastrointestinal infections, severe failure to thrive, chronic diarrhea with celiac-like enteropathy, and autoimmune manifestations including autoimmune hepatitis, dermatitis, and, in one case, autoimmune th
