Fig. 2.

Neonatal TREC content of individual patients with typical SCID (a) and other TCL (b) diagnoses at different screening sites (colors). TREC content reported in TRECs/reaction was converted to TRECs/μl. Partial DiGeorge syndrome and 22q11 deletion syndrome are displayed together as DiGeorge (b). Thirty three of 74 typical SCID patients displayed had 0 TRECs, compared to 22 out of 182 other TCL patients. Anonimyzed SCID patients had ADA-SCID (n = 4), γ chain-SCID (n = 2), Omenn-SCID (n = 2), RAG-SCID (n = 2), PNP-SCID (n = 1), undefined SCID (n = 7)
