Genes affected
ADA2 (HGNC:1839): (adenosine deaminase 2) This gene encodes a member of a subfamily of the adenosine deaminase protein family. The encoded protein is one of two adenosine deaminases found in humans, which regulate levels of the signaling molecule, adenosine. The encoded protein is secreted from monocytes undergoing differentiation and may regulate cell proliferation and differentiation. This gene may be responsible for some of the phenotypic features associated with cat eye syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

Vasculitis due to ADA2 deficiency Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Oct 18, 2017 | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with ADA2-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with serine at codon 62 of the ADA2 protein (p.Arg62Ser). The arginine residue is moderately conserved and there is a moderate physicochemical difference between arginine and serine. - |
