Labcorp Genetics (formerly Invitae), Labcorp RCV000819114 SCV000959757 uncertain significance Hyper-IgE recurrent infection syndrome 1, autosomal dominant; STAT3 gain of function 2018-10-17 criteria provided, single submitter clinical testing This sequence change replaces serine with glycine at codon 611 of the STAT3 protein (p.Ser611Gly). The serine residue is highly conserved and there is a small physicochemical difference between serine and glycine. This variant is not present in population databases (ExAC no frequency). This variant has been observed in several individuals affected with hyper-immunoglobulin E syndrome (PMID: 22751495, 23584561). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant disrupts the p.Ser611 amino acid residue in STAT3. Other variant(s) that disrupt this residue have been observed in affected individuals (PMID: 17881745), which suggests that this may be a clinically significant amino acid residue. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
