Hi Kurt, Jim,
Affymetrix arrays such as the hg-u133b were designed to target the 600 bp
at the 3' end of the transcript, not the start of the transcript.
We have found that the many-to-one mappings between probesets and genes
are often due to alternative splicing, use of alternative poly(A) sites,
or annotation errors.
