Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Published functional studies demonstrate increased STAT3 transcription in vitro (Jagle et al., 2020); This variant is associated with the following publications: (PMID: 29330115, 34875609, 34556655, 30942636, 28780238, 32577366, 30092289, 32499645, 32581362, 28253502, 31770611, 33519826, 31857100, 32888943, 32944850, 33864888, 22751495, 18602572) -

STAT3-related disorder Pathogenic:1
The STAT3 c.2144C>T variant is predicted to result in the amino acid substitution p.Pro715Leu. This variant has been reported in patients with a range of autoimmune disorders, occurring de novo in at least two patients (Sediva et al. 2017. PubMed ID: 28253502; Baxter et al. 2021. PubMed ID: 33864888; Besnard et al. 2018. PubMed ID: 29330115; Gonzalez-Mancera et al. 2020. PubMed ID: 32577366; Suh et al. 2019. PubMed ID: 30942636; Table S1, Thaventhiran et al. 2020. PubMed ID: 32499645; López et al. 2021. PubMed ID: 34875609). At PreventionGenetics, this variant has been reported de novo in an individual undergoing testing for autoimmune lymphoproliferative syndrome and paternally inherited in an individual with features of STAT3-related disease (Internal Data). An in vitro luciferase reporter assay showed this variant results in gain of function (Jägle et al. 2019. PubMed ID: 31770611). This variant is reported in 0.00088% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant is interpreted as pathogenic. -
Hyper-IgE recurrent infection syndrome 1, autosomal dominant;C4288261:STAT3 gain of function Pathogenic:1
This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 715 of the STAT3 protein (p.Pro715Leu). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with STAT3-related conditions (PMID: 28253502, 29330115; internal data). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 421171). 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 tolerated. Experimental studies have shown that this missense change affects STAT3 function (PMID: 28253502). For these reasons, this variant has been classified as Pathogenic. -
Hyper-IgE recurrent infection syndrome 1, autosomal dominant;C4014795:STAT3-related early-onset multisystem autoimmune disease Pathogenic:1
STAT3 NM_139276.2 exon 22 p.Pro715Leu (c.2144C>T): This variant has been reported in the literature in several individuals, including at least one de novo occurence, who presented with autoimmune and immunodeficiency phenotypes, including at least two with clincial diagnoses of Evan's syndrome (Sediva 2017 PMID:28253502, Besnard 2018 PMID:29330115, Forbes 2018 PMID:30092289, Suh 2019 PMID:30942636, Gonzalez-Mancera 2020 PMID:32577366, Jagle 2020 PMID:31770611, Thaventhiran 2020 PMID:32499645). This variant is not present in large control databases but is present in ClinVar, with several labs classifying this variant as pathogenic or likely pathogenic (Variation ID:421171). Evolutionary conservation and computational predictive tools suggest that this variant may impact the protein. In addition, functional studies have shown a gain-of-function effect of this variant (Jagle 2020 PMID:31770611). However, these studies may not accurately represent in vivo biological function. In summary, this variant is classified as pathogenic based on the data above. -
