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 c.1124G>A (p.R375H) alteration is located in exon 8 (coding exon 6) of the TMEM173 gene. This alteration results from a G to A substitution at nucleotide position 1124, causing the arginine (R) at amino acid position 375 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 375 of the TMEM173 protein (p.Arg375His). This variant is present in population databases (rs117897081, gnomAD 0.03%). 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: 1680234). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
