Cafodd y Mesur effaith uniongyrchol hefyd yng nghamau deddfwriaethol olaf Deddf Trawsblannu Dynol (Cymru) 2013 arloesol, lle penderfynwyd ar welliannau i gryfhau effaith yr UNCRC.  Cyhoeddodd Llywodraeth Cymru ei safbwynt y dylai plant cymwys gael dewis cynrychiolydd i fynegi’u caniatâd o ran rhoi organau.
Another example of the Measure having a direct impact was seen in the last legislative stages of the ground-breaking Human Transplantation (Wales) Act 2013 where reconsideration led to amendments in order to give greater effect to the UNCRC. The Welsh Government stated its position that competent children should be afforded the choice of appointing a representative to express consent to organ donation.
