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]

Ambry Genetics

Jan 16, 2024

The c.161C>T (p.A54V) alteration is located in exon 1 (coding exon 1) of the IL26 gene. This alteration results from a C to T substitution at nucleotide position 161, causing the alanine (A) at amino acid position 54 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
