FNDC11

Chr 20

fibronectin type III domain containing 11

The FNDC11 protein is a fibronectin type III domain-containing protein involved in cell adhesion and extracellular matrix interactions. Mutations cause autosomal recessive intellectual disability with developmental delay and variable additional features including seizures and behavioral abnormalities. The gene shows very high constraint against loss-of-function variants, indicating it is essential for normal human development.

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.
