Comment on phenotypes: Added phenotypes suggested from external expert review.Created: 13 Jun 2018, 1:44 p.m.
Comment on publications: added new publication PMID:29564582 (2018)Novel Mutation in CECR1 Leads to Deficiency of ADA2 with Associated Neutropenia.
(CECR1 previous approved HGNC gene symbol for ADA2)Created: 11 May 2018, 10:38 a.m.
Comment on list classification: changed from Amber to Green. Polyarteritis nodosa includes immunodeficiency phenotype and there are more than enough cases to support the association between ADA2 and Polyarteritis nodosa. In addition to this, there is a single publication PMID: 26922074 (2016) for a family with two affecteds where Deficiency of ADA2 (DADA2) was reported to cause vasculopathy and early-onset stroke, the case suggests that it should also be considered when evaluating patients with antibody deficiencies and immune dysregulation syndromes. Since they found that DADA2 can present clinically as common variable immunodeficiency or atypical systemic lupus erythematosus.Created: 30 Apr 2018, 4:12 p.m.
Comment on publications: added publications to support the PID phenotypeCreated: 30 Apr 2018, 3:53 p.m.
From OMIM: In 9 patients from 8 unrelated families with childhood-onset polyarteritis nodosa Zhou et al. (2014) PMID: 24552284 identified homozygous or compound heterozygous mutations in the ADA2 (previously known as CECR1) gene. All mutations except 1 were missense mutations. Also additional cases described in PMID: 24552285 and PMID:26922074Created: 30 Apr 2018, 3:52 p.m.
Comment on phenotypes: added phenotype, synonyms and MIMid from OMIMCreated: 30 Apr 2018, 3:43 p.m.
This gene was absent from the original PanelApp PID panel dataset (review April 2018). However it was listed in external expert immunodeficiency diagnostic gene list(s) GOSH or GRID. In this combined PID panel, this gene has been rated as AMBER and needs further curational review to assess pertinence prior to v1.Created: 20 Apr 2018, 12:25 p.m.
