British police said four men wearing balaclavas and armed with knives broke into Vertonghen's house while the Belgian international's wife and children were inside.
The 32-year-old was in Germany for Tottenham's Champions League last-16 second-leg defeat against Leipzig on Tuesday.
Vertonghen was an unused substitute as Tottenham lost 3-0 to crash out of the competition.
"We have been supporting Jan and his family through this terribly traumatic time," a Tottenham spokesperson said.
"We encourage anyone who has any information to come forward to help the police with their investigation." A Police spokesman said: "Police were called to a residential address in NW3 at 7.49pm on 10 March to a report of a burglary.
"Officers attended. It was reported four men wearing balaclavas, armed with knives, had forced entry to the property and stolen a number of items before leaving.
"Nobody was injured. The suspects had left the scene before officers arrived. There have been no arrests and inquiries continue."
The incident comes after Arsenal stars Mesut Ozil and Sead Kolasinac were targeted by armed moped riders while driving through north London earlier this season.
