241838_at is a significant hit in a gene expression analysis that I am currently working on. Affymetrix annotation provides Gene Symbol for this probe as
with additional notes
"This probe set was annotated using the Accession mapped clusters based pipeline to a UniGene identifier using 5 transcripts.".
There is no further annotation available for this probe in ADAPT, GATExplorer or AILUN. As this particular probe is a significant hit, I would like to know how can I report this. I would like to know the community is dealing with results based on such ambigous probes ? What could be the reason for Affymetrix to keep such a non-specific (GATExplorer says no genes are mapped to this probe) probe in the chip ?
