Genes affected

IFNA10 (HGNC:5418): (interferon alpha 10) This gene encodes a protein that belongs to the type I interferon family of proteins, and is located in a cluster of alpha interferon genes on chromosome 9. Interferons are small regulatory molecules that function in cell signaling in response to viruses and other pathogens or tumor cells. This gene is intronless and the encoded protein is secreted.

Collection Method: clinical testing

The c.199G>A (p.D67N) alteration is located in exon 1 (coding exon 1) of the IFNA10 gene. This alteration results from a G to A substitution at nucleotide position 199, causing the aspartic acid (D) at amino acid position 67 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
