A novel deletion mutation in GUCY2D gene may be responsible for Leber congenital amaurosis-1 disease: A case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo investigate genetic mutation(s) underlying retinal degeneration in a male patient.
methodsA seven-year-old male patient was referred to receive genetic counseling and molecular testing. Clinical examination was performed by slit-lamp examination and electroretinography (ERG). Molecular testing was undertaken through arrayed-primer extension (APEX) and Sanger sequencing.
resultsSlit-lamp examination and flat ERG were in favor of Leber congenital amaurosis (LCA) disease as well as fundus findings. The genetic screening revealed two novel homozygote deletion and duplication variants in intron 15 and exon 16 of the GUCY2D gene. Segregation analysis in the family supports the probable contribution of these two novel mutations in clinical representations of the patient.
conclusionsThis report provides more information about LCA disease and its relevant mutations in Iran. Considering the overlapping phenotypes observed in retinal degenerative disorders, comprehensive molecular testing is needed for precise diagnosis.
