[CIS PIDD] [cis-pidd] Heterozygous RAG1 mutation, isolated CD4 lymphopenia, warts and bone marrow hypoplasia

For the sake of completeness, I would also consider bone marrow failure
syndromes.  Have you done telomeres?  Cincinnati and Blueprint genetics
have good inherited bone marrow failure syndrome panels with some PID
overlap and includes TERT, TERC etc.  I'm sure there are similar panels
available somewhere in Europe.

He could be an evolving MDS.  I have a couple of patients who have normal
cytogenetics and only mildly dysplastic marrows that I am just following
for now.  They don't have the low CD4 counts or autoimmune features
though.  Chances are he will declare himself over time.

Regarding transplant and MDS, we frequently transplant young patients with
MDS but generally only those with a definitive diagnosis of MDS and usually
RAEB 1 or 2 subtypes as we know they are going to progress to AML.
