Need Prayer for disabled little girl

Hi everyone, I would greatly appreciate your prayers- there is a little girl in my family named Vivian that has a rare genetic condition called Angelman syndrome, it is a severe condition that affects the brain, people with this illness cannot speak. Vivian has to speak through a computer device, the doctors are saying she will never speak. I believe God has the power to heal her, please agree with me in prayer that she is healed and can speak! Thank you!

Lord God we lift up Vivian to You right now and we pray for a miracle in her current situation and for a healing of Angelman syndrome, we pray that You would supernaturally re-create her brain and that You would loose her tongue and that she would be able to speak plainly, we pray that she would be able to speak without the speech device! We also pray for the healing of her cognition! We also pray for Vivian and her entire family's' salvation and good health! Thank You God!
