a quick QUERY of GenBank release 99 under ACNUC (http://acnuc.univ-lyon1.fr/)
gives the following results :
number of human sequences with a coding sequence (sp=homo sapiens AND k=cds) :
22794
number of these with a key word of alternative splicing (k=@alt at splic@) :
268
-> 268 / 22794 = 1.2%
for all vertebrates : 593 / 60922 = 1.0%
Of course this is very crude, but I hope it helps a little.
