These results show contradicting results to previously published results [7], which may be due to the differences in age range of WAS patients (our four patients were all under 1 year old), in addition to technical difference in determining the repertoire (in this study, we used genomic DNA as our input for determining the repertoire compared to RNA which was previously used) and different WAS mutations. The gene discussed is WAS; the disease is Wiskott-Aldrich syndrome.
