Labcorp Genetics (formerly Invitae), Labcorp RCV003088175 SCV003478881 uncertain significance Hyper-IgE recurrent infection syndrome 1, autosomal dominant; STAT3 gain of function 2023-06-25 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with STAT3-related conditions. 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 sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 267 of the STAT3 protein (p.Ile267Val). ClinVar contains an entry for this variant (Variation ID: 2164716). 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. 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.
