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 GeneticsAug 12, 2021The c.980A>T (p.D327V) alteration is located in exon 9 (coding exon 8) of the IRF2 gene. This alteration results from a A to T substitution at nucleotide position 980, causing the aspartic acid (D) at amino acid position 327 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
