Genes affected
IRF2 (HGNC:6117): (interferon regulatory factor 2) IRF2 encodes interferon regulatory factor 2, a member of the interferon regulatory transcription factor (IRF) family. IRF2 competitively inhibits the IRF1-mediated transcriptional activation of interferons alpha and beta, and presumably other genes that employ IRF1 for transcription activation. However, IRF2 also functions as a transcriptional activator of histone H4. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2021The c.200C>G (p.P67R) alteration is located in exon 4 (coding exon 3) of the IRF2 gene. This alteration results from a C to G substitution at nucleotide position 200, causing the proline (P) at amino acid position 67 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
