Genes affected

DNASE1L3 (HGNC:2959): (deoxyribonuclease 1 like 3) This gene encodes a member of the deoxyribonuclease I family. The encoded protein hydrolyzes DNA, is not inhibited by actin, and mediates the breakdown of DNA during apoptosis. Mutations in this gene are a cause of systemic lupus erythematosus-16. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Feb 2012]

This sequence change replaces arginine, which is basic and polar, with lysine, which is basic and polar, at codon 285 of the DNASE1L3 protein (p.Arg285Lys). This variant is present in population databases (rs151161986, gnomAD 0.08%). This variant has not been reported in the literature in individuals affected with DNASE1L3-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The lysine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. Experimental studies have shown that this missense change does not substantially affect DNASE1L3 function (PMID: 24206041). 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. -
