Genes affected

IRF2BP2 (HGNC:21729): (interferon regulatory factor 2 binding protein 2) This gene encodes an interferon regulatory factor-2 (IRF2) binding protein that interacts with the C-terminal transcriptional repression domain of IRF2. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 558 of the IRF2BP2 protein (p.Val558Met). 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. 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 not been reported in the literature in individuals affected with IRF2BP2-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.007%). -
