> CVID: It is, no doubt, a strong possibility… but the conserved response to vaccines and lack of infections surprise me,

> XLP seems to me the most straightforward diafnosis: EBV in the lymph node, hypogamma after EBV infection, some auto-immune features (Coombs pos anti erythrocyte), EBV serology  with lack of EBNA, along with the “family pattern”: brother  with lack of IgA and same serology to EBV. But SAP and XIAP are both negative… ITK? We’ve just asked for its sequencing.

> Other HLH? We attend results for NK and CD8 cytotoxicity, perforin expression, sCD25.  Ferritin, TG , fibrinogen, etc are normal

> Leaky SCID? Seems odd… but he does have 34% of naïf T cells. Proliferation assyas are pending. Should we sequence the genes of leaky scid, namely RAG?

> Sarcoidosis? We aim to sequence NOD/CARD if everything else come out normal..
