Genes affected

IFNE (HGNC:18163): (interferon epsilon) Predicted to enable cytokine activity and type I interferon receptor binding activity. Predicted to be involved in several processes, including B cell activation; defense response to other organism; and lymphocyte activation involved in immune response. Predicted to be active in extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

IFNE links:

MIR31HG (HGNC:37187): (MIR31 host gene) This gene produces a long non-coding RNA that acts as a host gene for miR-31. This transcript may be involved in cellular pluripotency and regulate the differentiation of myoblasts and other tissues. This RNA was found to interact with Polycomb repressive proteins to repression transcription of genes involves in cell senescence. [provided by RefSeq, Dec 2017]

The c.364G>T (p.A122S) alteration is located in exon 1 (coding exon 1) of the IFNE gene. This alteration results from a G to T substitution at nucleotide position 364, causing the alanine (A) at amino acid position 122 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
