Overview

Splice-Alternative Profile Predictor (SpliceAPP) is an interactive web server for the prediction of RNA splicing in human, and a searchable database of collected splicing variants carried out by our prediction tool.

Prediction SpliceAPP predicts RNA splicing perturbed by human disease-assoicated near-exon intronic variants.

Approximately 10-30% of disease-associated genetic variants affect splicing. Splicing variants may generate deleteriously altered gene product which are determined as potential therapeutic targets. However, experimental diagnosis for splicing variants is time-consuming and reliable computational prediction tools have not been established, especially for the near-exon intronic splice region. The major challenge lies in the redundant and ill-defined branch sites and other splicing motifs therein.

In this study, we carried out unbiased massively parallel splicing assays on 5,307 disease-associated variants overlapped with branch sites, retrieved from HGMD, ClinVar and dbSNP databases, and collected 5,884 variants across the 5’ splice region.


From the 11% variants significantly altering 3’ss splicing, we identified two distinct splicing altering mechanisms, novel splice site competition and branch site dysfunction, whereas the splicing altering mechanism of the 5’ intronic variants is mainly the splice site destruction. Statistical learning combined with these molecular features allows precise prediction for altered splicing from an intronic end variant. Based on the training data, the predictive models accept variants -78 to -4 of the 3’ end and -3 to +30 of the 5’ end of the intron.
