Genes affected
IFNLR1 (HGNC:18584): (interferon lambda receptor 1) The protein encoded by this gene belongs to the class II cytokine receptor family. This protein forms a receptor complex with interleukine 10 receptor, beta (IL10RB). The receptor complex has been shown to interact with three closely related cytokines, including interleukin 28A (IL28A), interleukin 28B (IL28B), and interleukin 29 (IL29). The expression of all three cytokines can be induced by viral infection. The cells overexpressing this protein have been found to have enhanced responses to IL28A and IL29, but decreased response to IL28B. Three alternatively spliced transcript variants encoding distinct isoforms have been reported. [provided by RefSeq, Jul 2008]

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2024The c.1012G>A (p.V338I) alteration is located in exon 7 (coding exon 7) of the IFNLR1 gene. This alteration results from a G to A substitution at nucleotide position 1012, causing the valine (V) at amino acid position 338 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
