A novel mutation in Wiskott-Aldrich gene manifesting as macrothrombocytopenia and neutropenia

Wiskott-Aldrich syndrome (WAS) is a rare X-linked disorder, described as a clinical triad of microthrombocytopenia, eczema and recurrent infections. Different mutations in WAS gene have been identified, resulting in various phenotypes and a broad range of disease severity, ranging from classic WAS to X-linked thrombocytopenia and X-linked neutropenia. WAS in some cases can be fatal without haematopoietic stem cell transplantation early in life. In this particular case, we present a novel mutation with a unique presentation. An 18-year-old man incidentally found to have macrothrombocytopenia and neutropenia at 16 years of age later found to be hemizygous for c. 869T>C (p.Ile290Thr) mutation in WAS gene. The late presentation, absence of other manifestations of WAS and presence of macrothrombocytopenia, rather than microthrombocytopenia, which is usually a characteristic finding in WAS, misled the initial diagnosis. On review of literature, this mutation has not been reported as causing WAS.
