Genes affected

STING1 (HGNC:27962): (stimulator of interferon response cGAMP interactor 1) This gene encodes a five transmembrane protein that functions as a major regulator of the innate immune response to viral and bacterial infections. The encoded protein is a pattern recognition receptor that detects cytosolic nucleic acids and transmits signals that activate type I interferon responses. The encoded protein has also been shown to play a role in apoptotic signaling by associating with type II major histocompatibility complex. Mutations in this gene are the cause of infantile-onset STING-associated vasculopathy. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2014]

The missense c.659G>Tp.Arg220Leu variant in STING1 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The variant has been reported with allele frequency of 0.0004% in gnomAD Exomes and is novel not in any individuals in 1000 Genomes database. This variant has not been reported to the ClinVar database. The amino acid change p.Arg220Leu in STING1 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Arg at position 220 is changed to a Leu changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as Variant of Uncertain Significance VUS. -
