So far, I have found two variegated sports in our TC lab, one 'Ladyfinger' found last semester ('Sucrier') and one 'Apple' (Hawaiian Apple, aka 'Brazilian') found a couple weeks ago. The Ladyfinger made a few variegated leaves but seems to have mostly lost it, though its making some interesting leaves. I thought the Brazilian was reverting, and it still may be, while the base of the newest leaf is still showing variegation, the rest is green.
