[PAGID] Difficult diagnosis

[Torgerson, Troy]

I would add to Gigi's questions whether there is any data about whether the lymphocytes in each compartment (CD3,19,56) are hers or her mom's?  Would be worthwhile to check maternal chimerism.

I am uncertain what is wrong with this baby who certainly has a significant immune deficiency and would appreciate any ideas.
