This has been corrected.

I would also like to point out that unlike some other abilities that boost max HP based on a percentage, such as endurance and Afflicted Spectre, the boost from a Giant Gene doesn't count the actual total HP when it does its HP boost, it seems to ignore the HP given by items such as a red cloak or a Terrasque Shell and adds them afterward.

This is likely because item effects are read first, with flat HP being the last.
