Genes affected

IFNA13 (HGNC:5419): (interferon alpha 13) Predicted to enable cytokine activity and type I interferon receptor binding activity. Predicted to be involved in several processes, including B cell activation; lymphocyte activation involved in immune response; and positive regulation of peptidyl-serine phosphorylation of STAT protein. Predicted to be located in extracellular region. Predicted to be active in extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

The c.213G>C (p.Q71H) alteration is located in exon 1 (coding exon 1) of the IFNA13 gene. This alteration results from a G to C substitution at nucleotide position 213, causing the glutamine (Q) at amino acid position 71 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
