DLA to PIP

Hi our son has Noonan Syndrome, genetic disorder I act on his behalf I have been sent the letter and asked to call to claim. Anyone had experience of what they ask on the phone and at F2F interview very worried as he is high functioning but with specific issues.

Thanks looked at your guidance and was prepared for call which I did this am it was fine very routine and had the info they needed. Concern is he can drive and they may determine from that that he can do other things without prompting and support. Also given that there is no treatment or cure for his condition as it's genetic he rarely sees any health professionals geneticist as and when and cardiologist every 2 years for check up but not on any meds except for asthma. Will be reading your guide in depth before completing form when it arrives just dreading F2F feels like reliving all the past traumas again and focusing on the issues he has.
