Labcorp Genetics (formerly Invitae), Labcorp RCV003050468 SCV003441859 pathogenic Hyper-IgE recurrent infection syndrome 1, autosomal dominant; STAT3 gain of function 2022-12-02 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Ser636 amino acid residue in STAT3. Other variant(s) that disrupt this residue have been observed in individuals with STAT3-related conditions (PMID: 18602572, 20159255), which suggests that this may be a clinically significant amino acid residue. 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 not expected to disrupt STAT3 protein function. This missense change has been observed in individual(s) with clinical features of hyper IgE syndrome (PMID: 20159255, 28359783; Invitae). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces serine, which is neutral and polar, with tyrosine, which is neutral and polar, at codon 636 of the STAT3 protein (p.Ser636Tyr).
