PubMedID- 20864885 Recent findings: as a concept, newborn blood screening (nbs) has evolved from the detection of elevated levels of phenylalanine on filter paper to the application of dna-based technologies to identify t-cell lymphopenia in infants with severe combined immunodeficiency (scid).
PubMedID- 23590417 The phenotype is usually t-b+nk+ scid with lymphopenia where the clinical findings may be mild (cd3gamma) or severe (cd3delta, epsilon, zeta) owing to the underlying molecular defect.
PubMedID- 24506932 Results: despite the severe peripheral b-cell lymphopenia, patients with ada-deficient severe combined immunodeficiency showed a partial block in central bm development.
PubMedID- 25170474 Since its introduction as a public health programme in the united states in the early 1960s, newborn blood screening (nbs) has evolved from the detection of phenylalanine levels on filter paper to the application of dna-based technologies to identify t-cell lymphopenia in infants with severe combined immunodeficiency.
