On VOR 13L approach in JFK we might have gone below altitude at DMYHL due to wake turbulence encounter with proceeding aircraft. When I looked we might have been off altitude by about 150 FT to 200 FT. It was very close to DMYHL. We had a visual on the airport; and did not get a visual on aircraft ahead until about 1 NM before DMYHL. I was pilot not flying during the flight.
An EMB-145 Captain reported deviating below altitude assignment on arrival to JFK when they were distracted by a wake vortex encounter.
