DBNDD1

Chr 16

dysbindin domain containing 1

The DBNDD1 protein is predicted to regulate signal transduction and localize to the cytoplasm. Mutations cause disease through a predicted gain-of-function mechanism, though specific associated neurological conditions have not been definitively established. The inheritance pattern and detailed clinical phenotype remain to be fully characterized.

This gene has evidence for multiple mechanisms of pathogenicity (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function 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.
