Abstract
We developed a pilot program for the Persian Jewish community of greater Los Angeles. We screened for mutations responsible for four relatively frequent autosomal recessive conditions in Persian Jews in which effective interventions are available for each: Pseudocholinesterase deficiency (butyryl ch...

Abstract
APECED is a rare disorder, which can be associated with bilateral keratitis or diffuse corneal vascularization in addition to systemic findings and ectodermal signs. The Boston type 1 keratoprosthesis is a promising treatment option to improve visual acuity in patients with APECED with corneal invol...

Abstract
Clinical presentation and course of six patients with type 1 autoimmune polyglandular failure are presented. Mean age of the patients was 17.3 +/- 5.2 years and age at presentation was 10.16 +/- 4.35 years. Four out of six had the classic triad. All of the patients first presented with hypoparathyro...

Abstract
A compound heterozygous mutation of A19T/R257X was detected in the proband. Her father had the A19T mutation in exon 1, but this mutation was not detected in 100 unrelated healthy individuals. Her mother had the R257X mutation in exon 6. CONCLUSION: This is the first report about AIRE mutations in C...

In 2003, 63% of diabetic patients showed at least one pathologically increased antibody titer (2004: 60%). In 32% of the patients, increased antibody titers were clinically inapparent. Apart from diabetes mellitus type 1, in 2003, 31% suffered from other AIEK requiring therapy (2004: +3.6%): 22.3% h...

Abstract
Ten out of the 15 Venetian patients (66%) were homozygous for R257X or compound heterozygous with 1094-1106del13. One patient was homozygous for 1094-1106del13 and another for R139X. A novel mutation (1032-1033delGT) in combination with 1094-1106del13 was identified in one patient. No mutations were...

Mutations in the transcriptional regulator, Aire, cause APECED, a polyglandular autoimmune disease with monogenic transmission. Animal models of APECED have revealed that Aire plays an important role in T cell tolerance induction in the thymus, mainly by promoting ectopic expression of a large reper...

We examined the immunopathogenic mechanisms in this model, including identification of SAP Ags. We found that B7-2-deficient NOD mice exhibit changes in cytokine and chemokine gene expression in spleens over time. There was an increase in IL-17 and a decrease in IL-10 transcript levels at 4 mo (prec...

Abstract
Molecular analysis of FOXP3 in the 14 subjects revealed 13 missense and splice-site mutations, including 7 novel mutations. Enteropathy, generally associated with endocrinopathy and eczema, was reported in all patients, particularly in those carrying mutations within FOXP3 functional domains or muta...

Abstract
With the discovery of disease-causing mutations in the FOXP3 gene in patients with AIE, a dramatic advance in the understanding of AIE was made. Subsequent studies indicated that FOXP3 is a key transcription factor indispensable for regulatory functions of T cells pointing to a critical role of regu...

Abstract
We here demonstrate that antibodies against IFN-alpha cause highly significant down-regulation of interferon-stimulated gene expression in cells from APECED patients' blood by blocking their highly dilute endogenous IFNs. This down-regulation was lost progressively as these APECED cells matured in c...

We show that AIRE selectively interacts with histone H3 through its first plant homeodomain (PHD) finger (AIRE-PHD1) and preferentially binds to non-methylated H3K4 (H3K4me0). Accordingly, in vivo AIRE binds to and activates promoters containing low levels of H3K4me3 in human embryonic kidney 293 ce...

Abstract
NALP5 appears to be a tissue-specific autoantigen involved in hypoparathyroidism in patients with APS-1. Autoantibodies against NALP5 appear to be highly specific and may be diagnostic for this prominent component of APS-1.
