SFRP2
Chr 4secreted frizzled related protein 2
Also known as: FRP-2, SARP1, SDF-5
The protein functions as a soluble modulator of Wnt signaling through direct interaction with Wnt proteins and plays a role in eye retinal development and myogenesis. Mutations in this gene cause autosomal recessive retinal dystrophy with early childhood onset. The gene is not highly constrained against loss-of-function variants, consistent with a recessive inheritance pattern.
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.
