Wiskott-Aldrich syndrome (WAS) is a rare X-linked recessive disorder characterized by a triad of symptoms: immunodeficiency, thrombocytopenia,
and eczema. It arises from a mutation in the gene encoding the WAS protein (WASp). The disease can present with varying degrees of severity,
ranging from classic WAS, which features a severe phenotype, to milder forms, such as X-linked thrombocytopenia and X-linked neutropenia. WAS
primarily affects boys, although it can occur in isolated cases in girls, and it does not show any significant ethnic or geographic predisposition. This
article discusses a clinical case of WAS identified in two siblings from the same family. In this study, we analyzed primary medical documentation and
conducted a literature review. The syndrome is relevant for healthcare providers across various specialties, as it requires a comprehensive approach
to diagnosis and ongoing monitoring. Medical genetic diagnostics play a crucial role in the diagnosis, while treatment may involve hematopoietic stem
cell transplantation from a compatible donor. Additionally, this condition can be detected prenatally through appropriate medical consultation for the
family.
