چکیده

Methods We reviewed the contrast-enhanced brain MR, MR angiography (MRA), and digital subtraction angiography (DSA) examinations of 3 male patients with a confirmed molecular diagnosis of ADA2 deficiency and CNS involvement: two brothers (R312X and E328D mutations in compound heterozygosis) and a third unrelated patient (T360A homozygosis). Age at first MR examination was 6 years, 1 year 5 months, and 6 years 2 months, respectively.

Phenotypic variability in patients with ADA2 deficiency due to identical homozygous R169Q mutations

OBJECTIVE To determine the genotype-phenotype association in patients with adenosine deaminase-2 (ADA2) deficiency due to identical homozygous R169Q mutations inCECR1 METHODS: We present a case series of nine ADA2-deficient patients with an identical homozygous R169Q mutation. Clinical and diagnostic data were collected and available MRI studies were reviewed. We performed genealogy and haploty...

Mutations in CECR1 associated with a neutrophil signature in peripheral blood

BACKGROUND A reduction of ADA2 activity due to autosomal recessive loss of function mutations in CECR1 results in a newly described vasculopathic phenotype reminiscent of polyarteritis nodosa, with manifestations ranging from fatal systemic vasculitis with multiple strokes in children to limited cutaneous disease in middle-aged individuals. Evidence indicates that ADA2 is essential for the endo...

B cells characterization in ADA2 Deficiency patients

Introduction ADA2 deficiency, a recently described disease, is characterized by systemic vasculopathy and episodes of strokes. The defect is due to a loss of function mutation of CECR1 gene, codifying for Adenosine Deaminase 2 protein. This protein regulates the catabolism of extracellular adenosine, which we have recently shown is an important regulator of Class Switch Recombination in B lymph...

ADA2 deficiency: case report of a new phenotype and novel mutation in two sisters

The objective of this paper is to: describe the phenotype compound heterozygote for mutations in CECR1 in two children. We describe the clinical and immunological phenotype, including the assessment of ADA2 activity, cytokine expression, interferon-stimulated and neutrophil-stimulated gene signatures, and the results of CECR1 sequencing. The first patient presented with intermittent fever, cuta...

OR13-001 Loss-of-function mutations in CECR1, encoding adenosine deaminase 2 (ADA2), cause recurrent fevers and early onset strokes

Results The 5 unrelated patients shared 3 missense mutations in CECR1, encoding adenosine deaminase 2 (ADA2), with the genotypes A109D/Y453C, Y453C/G47A, G47A/ H112Q, R169Q/Y453C, and R169Q/28kb genomic deletion encompassing the 5’UTR and first exon of CECR1. All of the mutations are either novel or present at low frequency (<0.001) in several large databases. Computer modeling based on the cry...
