Patient Stories

Creed Pettit’s story

Creed Pettit, a 9 year boy from Miami, Florida had been slowly going blind since the day he was born. After a series of tests and analysis his doctors advised genetic testing. The test indicated that he had a rare genetic condition called Leber Congenital Amaurosis (LCA).

The mutation was identified in RPE65, a gene associated with retinal dystrophy, which leads to vision loss and complete blindness in certain patients. 

His genetic diagosntic results allowed his opthalomologist to treat him with Luxturna (voretigene neparvovec-rzyl), an FDA-approved gene therapy to treat children and adults with biallelic RPE65 mutation. Today Creed is able to see the world again.


  • Genetic testing ensured identification of mutation in RPE65 as the responsible gene for patient’s blindness
  • Subsequent gene therapy with Luxturna ensured restoration of sight
  • More than 60% of cases of blindness among infants are caused by inherited eye diseases such as congenital cataracts, congenital glaucoma, retinal degeneration, optic atrophy and eye malformations
