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]

Labcorp Genetics (formerly Invitae), Labcorp

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 310 of the TMEM173 protein (p.Arg310His). This variant is present in population databases (rs144683867, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with TMEM173-related conditions. ClinVar contains an entry for this variant (Variation ID: 541980). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -

Women's Health and Genetics/Laboratory Corporation of America, LabCorp

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: STING1 c.929G>A (p.Arg310His) results in a non-conservative amino acid change located in the STING ligand-binding domain (IPR055432) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 2.9e-05 in 1613732 control chromosomes, predominantly at a frequency of 0.00024 within the African or African-American subpopulation in the gnomAD database. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 240 fold of the estimated maximal expected allele frequency for a pathogenic variant in STING1 causing STING-associated vasculopathy with onset in infancy phenotype (1e-06). To our knowledge, no occurrence of c.929G>A in individuals affected with STING-associated vasculopathy with onset in infancy and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 541980). Based on the evidence outlined above, the variant was classified as likely benign. -
