While briefing the PDC neither of us saw the change to the departure procedure.  The Captain was the flying pilot and briefed the procedure and I was monitoring and also missed the change.  While on departure ATC gave us a 'direct to' which we didn't see the waypoint in the FMC and told ATC that we didn't have it on our plan.  They gave us a reroute and everything was fixed as far as they were concerned.  We discussed the occurrence in our debrief of the departure and realized that we had both missed the change.
I'm writing this to report that I unintentionally missed the revised segment that was given on our PDC. The revised segment changed the transition point and initial routing. I briefed the departure and missed the revised segment. It's totally my fault. I attribute it to being rusty. This was my first time flying since April and was out of my normal routine.
Air carrier flight crew reported they unintentionally missed the revised route segment given in their PDC.
