Identification of a de novo TSC2 variant in a Han-Chinese family with tuberous sclerosis complex.
Article in Journal of the Chinese Medical Association : JCMA, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundTuberous sclerosis complex (TSC) is an autosomal dominant disorder with a variety of clinical findings. Variants in the TSC complex subunit 1 gene (TSC1) or the TSC complex subunit 2 gene (TSC2) are responsible for TSC.
methodsPhysical examinations, computed tomography scans, and light microscopy analyses were performed on the TSC patient from a Han-Chinese pedigree. Whole-exome sequencing combined with Sanger sequencing were performed on the family members.
resultsThe TSC patient showed typical clinical features, including facial angiofibromas, gingival fibromas, a shagreen patch, hypomelanotic macules, ungual fibromas, subependymal nodules, multiple pulmonary cysts, and renal hamartomas. A de novo heterozygous c.5146delG (p.Ala1716Profs*110) variant in the TSC2 gene was identified in the TSC patient of the Han-Chinese family. To our knowledge, this is the first report of the TSC2 c.5146delG variant associated with TSC.
conclusionThe study expanding the disease-causing variant spectrum, suggests that whole-exome sequencing combined with Sanger sequencing may be a method for TSC diagnosis and differential diagnosis, and may facilitate the development of genetic counseling and targeted gene therapy for this disease.
