Abstract

To the Editor: Two recent clinical reports of retinal gene therapy with adeno-associated virus (AAV) vectors in patients with Leber's congenital amaurosis showed initial gains in visual function that subsequently declined.(1),(2) We previously reported early improvement in visual acuity in two of six patients who received retinal gene therapy in one eye (the study eye) to treat choroideremia,(3) a disease that is characterized by atrophy of the choriocapillaris and retinal pigment epithelium and involves vision loss that leads to blindness. Choroideremia is caused by loss-of-function mutations in the gene CHM. We delivered nonmutated CHM in an AAV vector (AAV.REP1) . . .

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
