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]
IFNG-AS1 (HGNC:43910): (IFNG antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.296T>C (p.L99S) alteration is located in exon 3 (coding exon 3) of the IL26 gene. This alteration results from a T to C substitution at nucleotide position 296, causing the leucine (L) at amino acid position 99 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
