TNFSF15
Chr 9TNF superfamily member 15
Also known as: TL1, TL1A, TNLG1B, VEGI, VEGI192A
The protein functions as a TNF ligand family cytokine that binds to receptors TNFRSF25 and TNFRSF6B, activates NF-kappaB signaling, and regulates endothelial cell apoptosis and angiogenesis inhibition. Based on the low pLI score (0.003) and high LOEUF score (0.95), this gene appears highly tolerant to loss-of-function mutations, and no established Mendelian diseases have been definitively linked to TNFSF15 mutations in the pediatric population. The predicted dominant-negative mechanism suggests potential pathogenicity through protein interference rather than haploinsufficiency.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Typical tolerance to LoF variation
Mild missense constraint
This gene has evidence for multiple mechanisms of pathogenicity (dominant-negative and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to dominant-negative as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.
Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
