I am using gene expression dataset [HG-U133_Plus_2] Affymetrix Human Genome U133 Plus 2.0 Array, I download CEL files from GEO and normalise it using RMA, some genes are found in multiple times while analysing the data.

For example: gene 'DDR1' has 3 expression values , how can I choose an expression of DDR1 from these 3 values, by using BiomaRt I can get chromosome details of these genes, but the result obtained from getBM contains more duplicate entries.

Is there is any other way to connect the genes with its chromosome details?

print the probes and expression values for DDR1. That may help
