RCV001995210 | SCV002250726 | likely pathogenic | Hyper-IgE recurrent infection syndrome 1, autosomal dominant; STAT3 gain of function | 2021-04-16 | criteria provided, single submitter | clinical testing | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. 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: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has been observed in individual(s) with clinical features of STAT3 gain-of-function (Invitae). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (ExAC no frequency). This sequence change replaces leucine with phenylalanine at codon 287 of the STAT3 protein (p.Leu287Phe). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and phenylalanine. |
