FRG2
Chr 4FSHD region gene 2
Also known as: FRG2A
The FRG2 protein is predicted to be located in the nucleus, but its specific function remains unknown. Mutations in FRG2 have not been definitively associated with any recognized human disease or clinical phenotype. The gene shows relatively low constraint against loss-of-function variants based on population genetics data.
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 dominant-negative.
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.
