DAB1
Chr 1ADDAB adaptor protein 1
DAB1 encodes a signaling adapter protein that mediates reelin signaling to regulate neuronal migration and differentiation during brain development. Mutations cause spinocerebellar ataxia 37, inherited in an autosomal dominant pattern. The gene is highly constrained against loss-of-function variants (pLI 0.999, LOEUF 0.215), indicating that complete loss of function is likely incompatible with normal development.

Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly LoF-intolerant (top ~10% of genes)
Mild missense constraint
This gene has evidence for multiple mechanisms of pathogenicity (loss-of-function and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to loss-of-function as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.
Literature Evidence
Predictions from Badonyi M, Marsh JA. PLoS ONE. 2024;19(8):e0307312. Mechanism ranking also informed by gnomAD constraint, ClinVar, and ClinGen data.
