Presentation
Various degrees of retinal atrophy are also present. [centogene.com]
The genetic cause for Leber congenital amaurosis in this patient is presently under investigation, AIPL1 being the strongest candidate. [medscape.com]
With age at presentation between 31 and 71 years the BCVA ranged from light perception to 20/25. All patients reported night blindness at presentation. [nature.com]

Treatment
PCR fragments were purified by ExoSAP-IT treatment (USB, Cleveland, OH), sequenced using Big Dye Termination chemistry (Applied Biosystems [ABI], Weiterstadt, Germany) and products separated on a DNA capillary sequencer (ABI 3100 genetic analyzer; ABI [nature.com]

Pathophysiology
The cloning of this disease gene should provide an insight into rod, as well as cone function and aid in our understanding of the pathophysiology of cone-rod dystrophy. [academic.oup.com]
