Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_Strong BP6_Very_Strong BS1 BS2

The NM_198282.4(STING1):​c.659G>A​(p.Arg220His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000788 in 1,614,130 control chromosomes in the GnomAD database, including 11 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R220L) has been classified as Uncertain significance.

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]

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0053483844).
• BP6: Variant 5-139478370-C-T is Benign according to our data. Variant chr5-139478370-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 475210.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00388 (591/152248) while in subpopulation AFR AF = 0.0134 (558/41538). AF 95% confidence interval is 0.0125. There are 6 homozygotes in GnomAd4. There are 258 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
• BS2: High AC in GnomAd4 at 591 AD gene.
