Description

The ADA2 c.506G>A variant is predicted to result in the amino acid substitution p.Arg169Gln. This variant in the compound heterozygous or homozygous state has been reported in patients with a complex immunologic and vascular phenotype, including polyarteritis nodosa (Navon Elkan et al. 2014. PubMed ID: 24552285; Van Eyck et al. 2015. PubMed ID: 25457153; Van Montfrans et al. 2016. PubMed ID: 26867732). This variant is reported in 0.19% of alleles in individuals of European (Finnish) descent in gnomAD. This variant is interpreted as pathogenic.
