This is normal for this chiptype. The HT12 contains a lot of probes that
have no proper annotation. These are mostly ESTs that have been
submitted to Genbank at some time, but have never been properly
attributed to any gene.

For most types of analysis these extra probes are basically worthless,
so I usually exclude them before the statistical analysis.
