TSNARE1
Chr 8t-SNARE domain containing 1
The protein functions as a SNARE complex component that facilitates synaptic vesicle fusion and intracellular protein transport at synapses. Mutations cause neurodevelopmental disorders with intellectual disability, autism spectrum disorder, and seizures. The gene shows autosomal recessive inheritance and has low constraint against loss-of-function variants.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Typical tolerance to LoF variation
Tolerant to missense variation
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.
