The variant received -4 classification points (ACGS-UK Somatic Oncogenicity v2025). B1_Strong

The NM_002188.3(IL13):c.*526A>C variant causes a 3 prime UTR change involving the alteration of a non-conserved nucleotide. The gene IL13 is a tumor suppressor gene (CancerMine: 1 TSG, 1 driver citations). The gene IL13 is a cancer driver gene (CancerMine: 1 TSG, 1 driver citations). The variant allele was found at a cumulative frequency of 0.68 (AC=108,015) in the gnomAD database across 158,878 control chromosomes, including 38,217 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.797. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

IL13 (HGNC:5973): (interleukin 13) This gene encodes an immunoregulatory cytokine produced primarily by activated Th2 cells. This cytokine is involved in several stages of B-cell maturation and differentiation. It up-regulates CD23 and MHC class II expression, and promotes IgE isotype switching of B cells. This cytokine down-regulates macrophage activity, thereby inhibits the production of pro-inflammatory cytokines and chemokines. This cytokine is found to be critical to the pathogenesis of allergen-induced asthma but operates through mechanisms independent of IgE and eosinophils. This gene, IL3, IL5, IL4, and CSF2 form a cytokine gene cluster on chromosome 5q, with this gene particularly close to IL4. [provided by RefSeq, Jul 2008]
