Genes affected
STAT3 (HGNC:11364): (signal transducer and activator of transcription 3) The protein encoded by this gene is a member of the STAT protein family. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. This protein is activated through phosphorylation in response to various cytokines and growth factors including IFNs, EGF, IL5, IL6, HGF, LIF and BMP2. This protein mediates the expression of a variety of genes in response to cell stimuli, and thus plays a key role in many cellular processes such as cell growth and apoptosis. The small GTPase Rac1 has been shown to bind and regulate the activity of this protein. PIAS3 protein is a specific inhibitor of this protein. This gene also plays a role in regulating host response to viral and bacterial infections. Mutations in this gene are associated with infantile-onset multisystem autoimmune disease and hyper-immunoglobulin E syndrome. [provided by RefSeq, Aug 2020]

| Pathogenic, criteria provided, single submitter | clinical testing | 3billion, Medical Genetics | Sep 01, 2022 | The variant is not observed in the gnomAD v2.1.1 dataset. It is located in a mutational hot spot and/or well-established functional domain in which established pathogenic variants have been reported (PMID:17881745). 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: 21792878, 27799162). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.80; 3Cnet: 0.35). The variant has been previously reported as de novo in at least two similarly affected unrelated individuals (PMID: 17881745, 18706697) and observed in multiple (>3) similarly affected unrelated individuals (PMID: 17881745, 18706697, 21792878). Different missense changes at the same codon (p.Val637Ala, p.Val637Leu) have been reported to be associated with STAT3-related disorder (PMID: 17881745, 20159255). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. - |

Hyper-IgE syndrome Pathogenic:1
| Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | May 16, 2017 | Variant summary: The STAT3 c.1909G>A (p.Val637Met) variant involves the alteration of a conserved nucleotide and is located in SH2 domain of the protein. 3/4 in silico tools predict a damaging outcome for this variant (SNPsandGO not captured due to low reliability index). This variant has been reported in several patients with Hyper IgE syndrome, including evidences of reported de novo occurrence and cosegregation with disease and is absent in 121926 control chromosomes. Functional studies showed that p.V637M affects the STAT3 function (Tamassia_2010, Giacomelli_2011). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic. Taken together, this variant is classified as "pathogenic". - |
Hyper-IgE recurrent infection syndrome 1, autosomal dominant;C4288261:STAT3 gain of function Pathogenic:1
| Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Oct 16, 2024 | This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 637 of the STAT3 protein (p.Val637Met). 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: 17881745, 18706697, 21792878). 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: 18308). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) 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: 26384563, 27799162). For these reasons, this variant has been classified as Pathogenic. - |
