The phenomenon of reverse mutation in a patient with Wiskott-Aldrich syndrome
Primary immunodeficiencies (PIDS) are genetically caused heterogeneous diseases of the immune system. One of the genetic phenomenon affecting the phenotypic diversity of PIDS is a reverse somatic mosaicism (RM) observed in different groups of PIDS. The majority of RM cases are described in patients with Wiskott-Aldrich syndrome (WAS). Despite the fact that PM does not always lead to a mild form of the disease, the presence of this phenomenon can cause the delay of diagnosis and start of the appropriate treatment. This article presents the case of a patient with Wiskott-Aldrich syndrome with a reverse mutation in the WAS gene. Parents gave their consent to use information about the child in the article.
