Literature
LitVar2 : PubMed links of articles citing this variant
LitVar is a web service that allows the search and retrieval of variant
relevant information from the biomedical literature. LitVar uses advanced
text mining and machine learning techniques to normalize different forms
of the same variant into a unique and standardized name so that all

dbscSNV / SpliceAI / AbSplice Max results
This table presents dbscSNV and SpliceAI raw delta scores (max distance: 50 bp, for academic users), when available. You can also run spliceAI via the spliceAIlookup API using a distance of 500 bp, and get also raw delta scores. This may take a while especially for genes with multiple transcripts but may help you identify new deep intronic variants. This also gives the opportunity to get spliceAi scores for large insertions or deletions. Details on raw or masked delta scores are available here. While the authors state that masked scores are preferentially used for variant interprétation, raw scores (unmasked) seem to be more informative. You can get masked delta scores with a +/- 500 bp window with this link. For substitutions, a pre-computed score for AbSplice is diplayed when relevant. AbSplice associates SpliceAI, MMSplice and tissue-specific splice site annotations (SpliceMaps). The scores represent the probability that a given variant causes aberrant splicing in a given tissue.

Radar view of splicing predictors
Values are normalised (0-1), 0 being the less damaging and 1 the most for each predictor.
AbSplice results
AbSplice associates SpliceAI, MMSplice and tissue-specific splice site annotations (SpliceMaps). The scores represent the probability that a given variant causes aberrant splicing in a given tissue. AbSplice thresholds are defined as 0.01 (low), 0.05 (intermediate), and 0.2 (high)
SpliceAI-visual results
SpliceAI-visual displays SpliceAI raw (absolute) predictions:
- Green and red highlights show the variation site on the wild-type and mutant track, respectively
- Positive orange bars represent predicted acceptor sites ([0;1]), and negative blue bars donor sites ([-1;0]), the spliceai raw score being the absolute value.
- The first track is the spliceai prediction for the entire MANE transcript.
- The second track is the prediction for the variant, +/- 10kb inside the transcript (i.e. not considering intergenic nucleotides).
- The "inserted nucleotides" track is used to display the scores of the nucleotides being part of the insertion (empty if no insertion)
- You can download the Wild-type and mutant bedgraphs in order to load them in your own Desktop IGV or the UCSC genome browser.
- Important notice: if your intronic variant is located more than 10kb from one of the two flanking exons, you are advised to click on the "SpliceAI-visual full transcript" button at the top of this text. Depending on the size of your transcript, within 30s-10 minutes (for the DMD gene, the bad news), the whole transcript prediction including the variant will appear as a new track in the igv.js browser, allowing a more accurate prediction for your variant. The good news being that if it has already been computed, it will load automatically.
