Introduction: Inborn error of immunity (IEI) includes variety of genetic disorders that affect both the innate and acquired immune system. The number of primary immune deficiency disorders is increasing due to advanced laboratory testing methods. The patients with IEI are susceptible to multiple infectious and non-infectious diseases، including autoimmune disorders، allergies، and malignancies. Several studies have shown an increasing prevalence of non-infectious disorders in patients in IEI. Among the non-infectious manifestations of primary immunodeficiency، allergic symptoms can play an effective and important role in diagnosis and treatment of these patients. Methods: Articles were searched in Google Scholar، PubMed، Web of Science، and Scopus databases. In this review، we have tried to use the latest and most reliable articles related to the subject that have been published in Persian and English language. Conclusion: Allergic diseases can be a common part of some primary immunodeficiency diseases. Even in some types of primary immunodeficiency، they are considered the main symptom and important indicator of the disease، which are very decisive factors for the diagnosis of immunodeficiency.
