However, an adequate test is critical to cost-effectiveness. The cost to detect 1 case of SCID would be $485,000.SCID screening could result in a large benefit to detected individuals, making screening relatively cost-effective in spite of the low incidence of the disease.
A nationwide screening program would cost an additional $23.9 million per year for screening costs but would result in 760 years of life saved per year of screening. SCID is a candidate for universal newborn screening, so there is a need to determine under which circumstances screening would be cost-effective.We assumed a screening program for SCID would use T-cell lymphopenia as the screening criterion and performed a cost-utility analysis comparing universal screening with screening only those with a family history of SCID.Assuming society is willing to pay $50,000 for every quality-adjusted life-year saved, a SCID screening test that cost less than $5 with a false-negative rate of 0.9% and a false-positive rate of 0.4% would be considered cost-effective. The incidence is unknown but may be more common than published estimates because infants frequently die of infection before diagnosis. Severe combined immunodeficiency (SCID) is a rare, treatable disorder of the immune system. Potential costs and benefits of newborn screening for severe combined immunodeficiency JOURNAL OF PEDIATRICS McGhee, S.View details for Web of Science ID 000273071500022 DOCK8 disruption is associated with a phenotype of severe cellular immunodeficiency characterized by susceptibility to viral infections, atopic eczema, defective T-cell activation and T(h)17 cell differentiation, and impaired eosinophil homeostasis and dysregulation of IgE. DOCK8 deficiency was associated with impaired activation of CD4+ and CD8+T cells.Autosomal-recessive mutations in DOCK8 are responsible for many, although not all, cases of autosomal-recessive hyper-IgE syndrome. Sequencing of patients without large deletions revealed 16 patients from 9 unrelated families with distinct homozygous mutations in DOCK8 causing premature termination, frameshift, splice site disruption, and single exon deletions and microdeletions. In all 5 patients, the deleted interval involved dedicator of cytokinesis 8 (DOCK8), encoding a protein implicated in the regulation of the actin cytoskeleton. The candidate gene was analyzed by genomic and cDNA sequencing to identify causative alleles in a total of 27 patients with autosomal-recessive hyper-IgE syndrome.Subtelomeric biallelic microdeletions were identified in 5 patients at the terminus of chromosome 9p. Homozygosity mapping was performed with 12 patients from 7 additional families. In the remaining patients with hyper-IgE syndrome, the genetic etiology has not yet been identified.We aimed to identify a gene that is mutated or deleted in autosomal recessive hyper-IgE syndrome.We performed genome-wide single nucleotide polymorphism analysis for 9 patients with autosomal-recessive hyper-IgE syndrome to locate copy number variations and homozygous haplotypes. Approximately 60% to 70% of patients with hyper-IgE syndrome have dominant mutations in STAT3, and a single patient was reported to have a homozygous TYK2 mutation. The genetic etiologies of the hyper-IgE syndromes are diverse.
