PHACTR1
Chr 6ADphosphatase and actin regulator 1
The protein binds actin monomers and regulates actin cytoskeleton dynamics, cell motility, endothelial cell survival, and cortical neuron migration and dendrite arborization. Mutations cause developmental and epileptic encephalopathy 70, inherited in an autosomal dominant pattern.

Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Typical tolerance to LoF variation
Mild missense constraint
The Badonyi & Marsh model scores loss-of-function highest, but genomic evidence most strongly supports dominant-negative as the primary mechanism.
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.
