SEC13
Chr 3SEC13 homolog, nuclear pore and COPII component
Also known as: D3S1231E, SEC13L1, SEC13R, npp-20
The protein functions as a component of the nuclear pore complex and COPII coat, involved in the biogenesis of COPII-coated vesicles at the endoplasmic reticulum and required for protein transport from the ER. Mutations cause autosomal recessive developmental delays, seizures, and intellectual disability with onset in early childhood. The gene shows moderate constraint against loss-of-function variants.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Typical tolerance to LoF variation
Mild missense constraint
The highest-scoring mechanism for this gene is dominant-negative.
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.
