Genetic Mosaicism as a Cause of Inborn Errors of Immunity.

J Clin Immunol 2021 Apr 16. Epub 2021 Apr 16.

Department of Pediatrics, Division of Rheumatology/Immunology, Washington University in St. Louis, 660 S. Euclid Ave. Box 8208, St. Louis, MO, 63110, USA.

Inborn errors of immunity (IEIs) are a heterogeneous group of disorders due to genetic defects in the immune response that have a broad clinical spectrum. Diagnosis of the precise genetic cause of IEI has led to improved care and treatment of patients; however, genetic diagnosis using standard approaches is only successful in ~40% of patients and is particularly challenging in "sporadic" cases without a family history. Standard genetic testing for IEI evaluates for germline changes in genes encoding proteins important for the immune response. Read More
