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	May 22, 2022	The variant is not observed in the gnomAD v2.1.1 dataset. Missense changes are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.90; 3Cnet: 0.99). Same nucleotide change resulting in same amino acid change (ClinVar ID: VCV000018304) and a different missense change at the same codon(p.Arg382Gln; ClinVar ID: VCV000018305) have been previously reported as pathogenic/likely pathogenic with strong evidence. Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. -

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 382 of the STAT3 protein (p.Arg382Trp). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with hyper IgE syndrome (HIES) (PMID: 17676033, 17881745, 17942886, 21324546, 24452316). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 18304). 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, 22581330). For these reasons, this variant has been classified as Pathogenic. -
