An in vivo genetic reversion highlights the crucial role of Myb-Like, SWIRM, and MPN domains 1 (MYSM1) in human hematopoiesis and lymphocyte differentiation

We here define a novel human immunodeficiency and provide evidence that MYSM1 is essential for proper immunohematopoietic development in human subjects. In addition, we describe one of the few examples of spontaneous in vivo genetic cure of a human immunodeficiency.
