Genes affected
IFNA17 (HGNC:5422): (interferon alpha 17) 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. Implicated in Crimean-Congo hemorrhagic fever and sarcoidosis.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 20, 2024 | The c.362C>T (p.A121V) alteration is located in exon 1 (coding exon 1) of the IFNA17 gene. This alteration results from a C to T substitution at nucleotide position 362, causing the alanine (A) at amino acid position 121 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
