The morph is not gene-fixed, and in fact suffers from a genetic disorder or other impairing mutation. The player and gamemaster should agree on a defect appropriate to their game. Some possibilities include: heart disease, diabetes, cystic fibrosis, sickle-cell disease, hypertension, hemophilia, or color blindness. A minor genetic disorder creates minor complications and/or occasional health problems. The gamemaster must determine the exact effects of the disorder on gameplay, as appropriate. This trait is only available for flats.
