Deleting rows using complex(custom) filtering

Hi all,

I'm new to XL programming therefore we will be hopefully seeing each other more often.

At the moment I'm helping out molecular biologists with an excel sheet they need 'filtered" in a specific way, but i cant seem to get my head around it since I'm not that good

In the attached example i need to write a script which will filter out some specific occurences of genes and their positions. The VBA filter should in practice:

delete all the the ROWS of data WHERE:
= for a unique "Gene.name" ALL the "Position.build" numbers are the SAME

The rest must be untouched.

For example:
most of the rows contain "gene.name"s with alot of same "position.build"s but a few which are different or a group of "position.build"s that are different. In this case everithing should be kept as is and untouched.

Wooow what a challenge ah? at least for me it is untill i learn...

Like I said, i'm new to this all and would appretiate some pointers on how to use the code and if possible comments within code so that i could learn and then be more proficient and be able to help around the lab.
