Red List (low evidence)

Kury et al. described a single patient from consanguineous parents carrying a homozygous frameshift mutation in POU2AF1, encoding for Bob1, presenting with agammaglobulinemia with normal B cells. Functional data showed that Bob1 deficiency ex vivo and in a mouse KO model reduced B-cell responsiveness, impaired plasmablast formation and immunoglobulin secretion.
