not provided Pathogenic:1
Published functional studies demonstrate a damaging effect with significantly increased STAT3 binding activity consistent with a gain of function mutation; Not observed at significant frequency in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 34128135, 31770611, 30092289, 34573280, 34134972, 33726816, 33057194, 36228738, 34390446, 37976116, 35982159, 15919823, 25359994) -
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 tryptophan, which is neutral and slightly polar, at codon 152 of the STAT3 protein (p.Arg152Trp). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with multi-organ autoimmune disease (PMID: 25359994). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 224846). 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: 25359994). For these reasons, this variant has been classified as Pathogenic. -
