Comment on list classification: Associated with relevant phenotypes in OMIM and as possible Gen2Phen gene. At least 3 large inframe deletion variants have been reported in unrelated Familial cold autoinflammatory syndrome 3 614468 cases. These deletions remove, the C-terminal Src-homology-2 (cSH2) domain, which is autoinhibitory and normally prevents constitutive enzymatic function, hence the deletions are gain of function (PMID 22236196). The missense variant (NM_002661, c.2120C>A, p.Ser707Tyr) also falls within the cSH2 domain, it does not result in loss of inhibition alone, but requires other stimulating factors also (PMID 23000145)Created: 9 May 2018, 11:55 a.m.

This gene was present in the original PanelApp PID panel dataset (review in April 2018) rated as Amber. The gene is present in the 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, 10:29 a.m.

Comment on list classification: Variants in this gene are certainly linked to immunodeficiency. From literature review, found 2 papers documenting variation in this gene being linked to hypo-gammaglobulinaemia, the first paper 22236196, citing 3 individuals being treated for hypo-gammaglobulinaemia, however not clear if these individuals are related.Created: 15 Aug 2017, 1:17 p.m.
