Wake turbulence could lead to a loss of control, and a departure from the intended flight path. However, if the transponder plots are accurate, there appears to be a steady loss of speed over the course of a substantial period of time. I say substantial because response for any speed deviation from your Vref + 5 (or whatever it is for THY) should be immediate, particularly if you are slow. As someone else posted, it appears to have been on the G/S for at least some of the approach.
Of course it will come out in the investigation, but I am keen to see exactly what mode of automatics were in use at the time.
