This table lists the methods used to annotate genes either directly to the term mRNA 5'-splice site recognition (5 genes) or to its variants containing one or more qualifiers (0 genes). Note that some genes may have been annotated by more than one method so the numbers in the table below may not add up to the totals given here.
