Rare Diseases Symptoms Automatic Extraction

Newborn screening for severe T and B cell lymphopenia identifies a fraction of patients with Wiskott-Aldrich syndrome.

[severe combined immunodeficiency]

The lack or marked reduction of recently formed T and B cells provides a basis for neonatal screening for severe combined immunodeficiencies (SCID) and X-linked agammaglobulinemia (XLA). Newborns with other conditions are also identified if a severe T or B cell lymphopenia is present at birth. We retrospectively analyzed Guthrie card samples from 11 children with Wiskott-Aldrich syndrome (WAS), a rare disease that requires early diagnosis and treatment, to determine whether combined T-cell receptor excision circle (TREC) and kappa-deleting recombination excision circle (KREC) screening could identify these patients. 4 of 11 patients showed markedly reduced TREC or KREC copy numbers in their DBS as compared to storage-time matched controls and prospectively screened Swedish and German newborns. No correlation was observed between the WAS gene mutations, the clinical severity/course and the result of the screening assay. A diagnosis of WAS should thus be considered in newborns with positive TREC or KREC screening results.
