Identification and genetic analysis of rare variants in myosin family genes in 412 Han Chinese congenital heart disease patients.
Article in Molecular genetics & genomic medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundMyosin family genes, including those encoding myosin heavy chain 6, myosin heavy chain 7, myosin light chain 3, and myosin light chain 2 (MYL2), are important genetic factors in congenital heart disease (CHD). However, how these genes contribute to CHD in the Han Chinese population remains unclear.
methodsWe sequenced myosin family genes in a Han Chinese cohort comprising 412 CHD patients and 213 matched controls in the present study. A zebrafish model was used to evaluate the pathogenicity of rare mutations in MYL2.
resultsWe identified 30 known mutations and 12 novel mutations. Furthermore, the contributions of two novel mutations, MYL2 p.Ile158Thr and p.Val146Met, to CHD were analyzed. The p.Ile158Thr mutation increased MYL2 expression. In zebrafish embryos, injection of myl2b-targeting morpholinos led to aberrant cardiac structures, an effect that was reversed by expression of wild-type MYL2 but not MYL2 p.Ile158Thr and pVal146Met.
conclusionsOverall, our findings suggest that MYL2 p.Ile158Thr and p.Val146Met contribute to the etiology of CHD. The results also indicate the importance of MYL2 in heart formation.
