Dear Pere,
the patient seems a bit too young to consider PCFT (folate transporter)
deficiency or other "replication defects" like dyskeratosis related
disorderts (e.g. RTEL1).
These diseases might however aggravate if patients encounter a
"replication challenge" like early systemic infections. We picked up
young pts with these defecst who presented with early onset bone marrow
failure (affecting all lineages). Good luck, best wishes Carsten
