Application of family whole-exome sequencing for prenatal diagnosis-an analysis of 357 cases.

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
Objective: Translation of fertility risks through whole-exome sequencing of family lines to identify variants that explain patient's clinical phenotypes. Methods: 1. Using techniques such as amniotic fluid, chorionic villus, or umbilical cord blood sampling, intact fetal cells were extracted for cell culture and subsequently analyzed using chromosomal karyotyping and chromosomal microarray techniques. 2. With fully informed consent, fetuses and their parents whose genetic etiology could not be detected by karyotyping combined with chromosomal microarray technology had their cellular DNA subjected to whole-exome sequencing of the pedigree. 3. Pathogenic variants were screened in combination with fetal ultrasound phenotyping and ACMG variant rating guidelines for variant interpretation, followed by inviting multidisciplinary experts to conduct an in-depth analysis and indicate fetal-related ultrasound abnormalities. 4. Genetic counseling is assisted based on the results. Results: 1. Of the 357 fetuses included in the study, 33 (33/357, 9.24%) had a successful genetic etiology identified through family-wide exome sequencing combined with ultrasound phenotyping. 2. The results showed that skeletal anomalies were the most frequent, accounting for 15 cases (15/33, 45.45%), followed by multiple malformations in 7 cases (7/33, 21.21%), renal anomalies in 3 cases (3/33, 9.09%), soft index anomalies in 2 cases (2/33, 6.06%), neurological anomalies in 2 cases (2/33, 6.06%), cleft lip and palate in 1 case (1/33, 3.03%), cardiac abnormality in 1 case (1/33, 3.03%), hydatidiform mole in 1 case (1/33, 3.03%), and cataract in 1 case (1/33, 3.03%). 3. During whole-exome sequencing, three previously unreported variant sites were identified: Conclusion: 1. This study provides robust data supporting the application of whole-exome sequencing of family lines in clinical practice, offering valuable reference information for clinicians. 2. The newly discovered variants significantly enhance the relevant genetic databases. 3. Genetic diagnosis can offer clear guidance regarding the decision to continue with the pregnancy and future reproductive choices.
