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]
LINC00184 (HGNC:37192): (long intergenic non-protein coding RNA 184)

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.199C>T (p.P67S) alteration is located in exon 1 (coding exon 1) of the IRF2BP2 gene. This alteration results from a C to T substitution at nucleotide position 199, causing the proline (P) at amino acid position 67 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 67 of the IRF2BP2 protein (p.Pro67Ser). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with IRF2BP2-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
