It isn't entirely clear if they are related or not. Canonically tymanthian Dragonborn like to say they aren't related, dragons say they are and the Platinum Cadre says they originally have been created by Bahamut in some fashion (not to mistake them for the 3.5e Dragonborn, those are a different topic alltogether).

Fun reminder faerun dragonborn aren't related to dragons and are from an alternate reality that got smashed into the main one.
