Variant summary
Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP6BS1BS2
The NM_198282.4(STING1):c.575G>T(p.Gly192Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000217 in 1,614,210 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/23 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G192D) has been classified as Uncertain significance.

STING-associated vasculopathy with onset in infancy Uncertain:2
This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 192 of the TMEM173 protein (p.Gly192Val). This variant is present in population databases (rs201096097, gnomAD 0.06%), including at least one homozygous and/or hemizygous individual. This missense change has been observed in individual(s) with disorders of immunity (PMID: 35086391, 35482138). ClinVar contains an entry for this variant (Variation ID: 475208). 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. -
STING1 c.575G>T (rs201096097) is rare (<0.1%) in a large population dataset (gnomAD: 73/282854 total alleles; 0.03%; 1 homozygote) and has not been reported in the literature, to our knowledge. There is an entry for this variant in ClinVar (Variation ID: 475208). Of three bioinformatics tools queried, one predicts that the substitution would be possibly damaging, while two predict that it would be tolerated. The glycine at this position is conserved in most mammals, but not in the other species assessed. We consider the clinical significance of c.575G>T to be uncertain at this time. -
Inborn genetic diseases Uncertain:1
The c.575G>T (p.G192V) alteration is located in exon 6 (coding exon 4) of the TMEM173 gene. This alteration results from a G to T substitution at nucleotide position 575, causing the glycine (G) at amino acid position 192 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
STING1-related disorder Uncertain:1
The STING1 c.575G>T variant is predicted to result in the amino acid substitution p.Gly192Val. To our knowledge, this variant has not been reported in the literature in association with STING1 (TMEM173)-related disease but has been reported in individuals with early-onset systemic lupus erythematosus (Dasdemir et al. 2022. PubMed ID: 35086391), inborn errors of immunity (El Hawary et al. 2022. PubMed ID: 35482138), and autism spectrum disorder (Tuncay et al. 2023. PubMed ID: 37492102). This variant is reported in 0.065% of alleles in individuals of South Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/5-138858039-C-A). Although we suspect that this variant may be benign, the clinical significance of this variant is uncertain at this time due to the absence of conclusive functional and genetic evidence. -
