Variant summary: STAT3 c.1145G>A (p.Arg382Gln) results in a conservative amino acid change located in the STAT transcription factor, DNA-binding (IPR013801) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 251470 control chromosomes. c.1145G>A has been reported in the literature in multiple individuals affected with Hyper IgE Syndrome (e.g. Holland 2007). It has been observed as de novo and also seen to segregate with disease. These data indicate that the variant is very likely to be associated with disease. Additionally, other variants affected the same codon have been associated with Hyper-IgE syndrome in HGMD and ClinVar (e.g. R382G, R382P and R382W). At least one publication reports experimental evidence evaluating an impact on protein function by severely reducing the DNA binding ability of the homodimer (He_2012). The following publications have been ascertained in the context of this evaluation (PMID: 17881745, 20159255, 22581330).Five submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

The variant is not observed in the gnomAD v2.1.1 dataset. Predicted Consequence/Location: Missense changes are a common disease-causing mechanism. Functional studies provide moderate evidence of the variant having a damaging effect on the gene or gene product (PMID: 17676033). In silico tool predictions suggest damaging effect of the variant on gene or gene product [REVEL: 0.79 (>=0.6, sensitivity 0.68 and specificity 0.92); 3Cnet: 0.93 (>=0.6, sensitivity 0.72 and precision 0.9)]. Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000018305 /PMID: 17676033). The variant has been observed in at least two similarly affected unrelated individuals (PMID: 17676033, 17881745). The variant has been previously reported as assumed (i.e. paternity and maternity not confirmed) de novo in at least one similarly affected unrelated individual (PMID: 17881745). Different missense changes at the same codon (p.Arg382Gly, p.Arg382Leu, p.Arg382Pro, p.Arg382Trp) have been reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000018304, VCV000018307, VCV002099076 /PMID: 17676033, 17881745, 20093388, 32944025 /3billion dataset). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -

This variant has been observed to be de novo in individuals affected with hyper-IgE syndrome (Holland SM, 2007). It also segregates with hyper-IgE syndrome in a family and has been identified in several individuals affected with hyper-IgE syndrome (Minegishi Y, 2007) and an individual with selective IgG subclass deficiency (Ohnishi H, 2016). This variant has been reported to affect STAT3 protein function (Minegishi Y, 2007). This sequence change replaces arginine with glutamine at codon 382 of the STAT3 protein (p.Arg382Gln). Other variant(s) that disrupt p.Arg382 residue have been determined to be pathogenic (Renner ED, 2007). The variant has been reported to the ClinVar database as Pathogenic. The p.Arg382Gln variant is novel (not in any individuals) in gnomAD Exomes and 1000 Genomes. The variant is predicted to be damaging by both SIFT and PolyPhen2. The amino acid change p.Arg382Gln in STAT3 is predicted as conserved by GERP++ and PhyloP across 100 vertebratesFor these reasons, this variant has been classified as Pathogenic. -

Published functional studies demonstrate markedly enhanced STAT3 AGG-element binding, increased AGG-promoter activation activity, impaired Th17 response, and reduced IgG levels resulting in increased susceptibility to recurrent infections (Minegishi et al., 2007; Xu et al., 2015; Moffitt et al., 2018); Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 18591410, 27474157, 29368105, 29402895, 20859667, 21288777, 21792878, 22500887, 22581330, 23830147, 20093388, 26384563, 25686613, 26280891, 17676033, 24452316, 17881745, 27302695, 28197791, 30410549, 31596517, 32912316, 32499645, 32581362, 33225392, 32888943, 33717144, 18602572, 29463618) -

Hyper-IgE recurrent infection syndrome 1, autosomal dominant;C4288261:STAT3 gain of function    Pathogenic:1 
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 382 of the STAT3 protein (p.Arg382Gln). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with hyper-IgE syndrome (PMID: 17676033, 17881745, 20301786, 24452316, 27302695). In at least one individual the variant was observed to be de novo. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 18305). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt STAT3 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects STAT3 function (PMID: 17676033, 26384563). This variant disrupts the p.Arg382 amino acid residue in STAT3. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 17676033, 17881745, 17942886, 22581330). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
