Splicing predictions

MaxEntScan results

MaxEntScan scores are presented in the two following tables. Selected scores have:

  • a |variation| > 15% and
  • a raw score for mutant or wild-type of at least 3
The upper sequence shows the variation site in red, and the lower sequence the putative splice site considered by MaxEntScan (putative introns are shown as lower case and exons as upper case).


MaxEntScan 5'ss scores
Wild-type sequence Score Mutant sequence Score Variation(%)
No significant MaxEnt 5'ss scores found.


MaxEntScan 3'ss scores
Wild-type sequence Score Mutant sequence Score Variation(%)
No significant MaxEnt 3'ss scores found.

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.

Features Values Descriptions
spliceAI AG: 0.00 (-25) Acceptor Gain, Δ score 0-1 (relative position in bp), thresholds ≥ 0.2|0.5|0.8 for impact
spliceAI AL: 0.00 (39) Acceptor Loss, Δ score 0-1 (relative position in bp), thresholds ≥ 0.2|0.5|0.8 for impact
spliceAI DG: 0.00 (19) Donor Gain, Δ score 0-1 (relative position in bp), thresholds ≥ 0.2|0.5|0.8 for impact
spliceAI DL: 0.00 (1) Donor Loss, Δ score 0-1 (relative position in bp), thresholds ≥ 0.2|0.5|0.8 for impact
