Somatic revertant mosaicism has been described in an increasing number of primary immunodeficiency. Revertant cells with a selective advantage in vivo have been associated with attenuated clinical phenotype in some cases. In this research, we report an atypical case of X-linked severe combined immunodeficiency presenting with Omenn syndrome-like syndrome due to revertant mosaicism. We show the underlying mechanism and the importance of revertant mosaicism as a possible cause for variable phenotypic expression. The study of this fascinating phenomenon also continues to provide unique opportunities to evaluate the biological effects of restored gene expression and deserves close investigation.
