SPRY2

Chr 13AD

sprouty RTK signaling antagonist 2

Also known as: IGAN3, hSPRY2

The protein antagonizes fibroblast growth factor (FGF) signaling pathways by inhibiting FGF-mediated ERK1/2 phosphorylation and also inhibits CBL-mediated EGFR ubiquitination. Mutations cause IgA nephropathy with autosomal dominant inheritance. This gene is highly constrained against loss-of-function variants (pLI = 0.97), suggesting additional phenotypes may be associated with pathogenic variants.

Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 0.97). One damaged copy is likely sufficient to cause disease.
