RAPGEF1
Chr 9Rap guanine nucleotide exchange factor 1
This gene encodes a guanine nucleotide exchange factor that transduces signals from CRK to activate RAS family GTPases and is essential for nerve growth factor-induced neurite outgrowth, cell adhesion, and endothelial barrier function. The extremely high pLI score (1.0) and low LOEUF score (0.222) indicate the gene is highly intolerant to loss-of-function mutations, suggesting pathogenic variants would likely cause autosomal dominant disease. However, specific neurogenetic disorders caused by RAPGEF1 mutations have not yet been clinically characterized.
