GPRASP3
Chr XG protein-coupled receptor associated sorting protein family member 3
Also known as: BHLHB9, GASP3, p60TRP
The encoded protein promotes neuronal survival and differentiation and regulates neurosynaptogenesis by inducing phosphatase PP2A activity, which leads to APP dephosphorylation and inhibits BACE1-mediated APP processing. Mutations in GPRASP3 cause autosomal recessive neurodevelopmental disorders affecting the central nervous system. The gene shows relatively low constraint to loss-of-function variation.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Mild missense constraint
The highest-scoring mechanism for this gene is gain-of-function.
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.
