Genes affected

IFNA5 (HGNC:5426): (interferon alpha 5) 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.481C>A (p.P161T) alteration is located in exon 1 (coding exon 1) of the IFNA5 gene. This alteration results from a C to A substitution at nucleotide position 481, causing the proline (P) at amino acid position 161 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
