i can`t upgrade itI think that's the "cutting-edge genetic sequencer." in Penthouse upgrades? It could be something beyond that for all I know, sounds right by the name though. I don't have it unlocked in my current game either atm, requires more than 11k rep. That allows you to fuck with the traits of girls. Traits are normally hidden without that upgrade.
Genetic Modification
The fabricator must be upgraded before it can produce treatments to alter genes
