Missing gene title

Question

[zelda]

Hi,

I am using GEO2R to generate deferentially expressed genes between two conditions. However, after defining the groups and viewing the top 250 genes, all attributes are found such as the adjusted p-value and P-value. The problem is that gene title and gene symbol are missing in some columns. What does that mean?

Thank you!

These are control probes. Ignore them.
