Cell Rep 13: 1033–1045. … WebThe mutation creates a new donor splice site (AGgtgagc) in a late exonic position that results in an aberrant exon 2 definition. Usage of this cryptic donor site leads to a mutant in-frame transcript shortened of 54 nucleotides (p.M99_S116del). Normal splicing by the naturally occurring donor site (gtaagt) is shown for comparison.

WebA “splice site” mutation occurs in an intron, in a splice acceptor or donor site (2bp into an intron adjacent to the intron/exon junction), defined by Sequence Ontology. “Splice region” mutations are mutations that occur near the intron/exon junction, defined by Sequence Ontology.
