Performance Evaluation of SpliceAI for the Prediction of Splicing of <i>NF1</i> Variants
Neurofibromatosis type 1, characterized by neurofibromas and café-au-lait macules, is one of the most common genetic disorders caused by pathogenic <i>NF1</i> variants. Because of the high proportion of splicing mutations in <i>NF1</i>, identifying variants that alter splicin...
