Genes affected

IL26 (HGNC:17119): (interleukin 26) This gene was identified by its overexpression specifically in herpesvirus samimiri-transformed T cells. The encoded protein is a member of the IL10 family of cytokines. It is a secreted protein and may function as a homodimer. This protein is thought to contribute to the transformed phenotype of T cells after infection by herpesvirus samimiri. [provided by RefSeq, Jul 2008]

Feb 28, 2024

The c.284G>C (p.G95A) alteration is located in exon 3 (coding exon 3) of the IL26 gene. This alteration results from a G to C substitution at nucleotide position 284, causing the glycine (G) at amino acid position 95 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
