The incident occurred during last night's 3-1 for the Seagulls in the FA Cup fourth-round replay.
Speaking after the game, Hughton said: "What we heard tonight is not nice. What we have in Gaetan is a very upright, respectable individual.
"For those who make those chants that's their individual choice and it's down to the authorities and governors of the game to deal with. The game in recent years has acted on such things really well.
"All Gaetan wants to do is very much get on with his football. He has conducted himself impeccably."
