• Description: Background: Agammaglobulinemia due to variants in IGLL1 has traditionally been considered an exceedingly rare form of severe B-cell deficiency, with only 8 documented cases in the literature. Surprisingly, the first agammaglobulinemic patient identified by newborn screening (NBS) through quantification of kappa-deleting recombination excision circles harbored variants in IGLL1.
