RASD1
Chr 17ras related dexamethasone induced 1
Also known as: AGS1, DEXRAS1, MGC:26290
The RASD1 protein is a small GTPase that activates G-protein signaling and acts as a nucleotide exchange factor for Gi-Go proteins. Mutations in RASD1 cause neurodevelopmental disorders with intellectual disability, typically presenting in early childhood. The gene follows an autosomal dominant inheritance pattern.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
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.
