Genes affected

IFNL3 (HGNC:18365): (interferon lambda 3) This gene encodes a cytokine distantly related to type I interferons and the IL-10 family. This gene, interleukin 28A (IL28A), and interleukin 29 (IL29) are three closely related cytokine genes that form a cytokine gene cluster on a chromosomal region mapped to 19q13. Expression of the cytokines encoded by the three genes can be induced by viral infection. All three cytokines have been shown to interact with a heterodimeric class II cytokine receptor that consists of interleukin 10 receptor, beta (IL10RB) and interleukin 28 receptor, alpha (IL28RA).

The c.455A>G (p.H152R) alteration is located in exon 4 (coding exon 4) of the IFNL3 gene. This alteration results from a A to G substitution at nucleotide position 455, causing the histidine (H) at amino acid position 152 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
