SPI1 Mutations Expand the Agammaglobulinemia Genetic Map
A novel de novo SPI1 mutation has been identified in a Chinese patient with agammaglobulinemia, adding another piece to the complex genetic puzzle of this primary immunodeficiency. This finding suggests that SPI1 should be considered in the diagnostic workup of patients with unexplained B-cell deficiency, particularly in cases where other known genetic causes have been excluded.
