1 · What the graph read from it

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.

2 · The registry

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

BACKGROUND AND

objectiveMutations in the KAT6A gene, which encodes a histone acetyltransferase, have been linked to an autosomal dominant neurodevelopmental disorder known as the Arboleda-Tham syndrome. The clinical symptoms of this disorder are nonspecific and pose challenges to accurately characterizing the condition based solely on these symptoms. This study aimed to establish a definitive diagnosis in three patients with intellectual disability and multiple congenital anomalies, and to elucidate the genotype-phenotype correlation based on the existing literature. PARTICIPANTS AND

methodsIn this study, we investigated three probands with severe intellectual disability, global developmental delay, hypotonia, gait disturbance, microcephaly, scoliosis, abnormal heart morphology, strabismus, gastrointestinal dysmotility, and abnormal facial shape, using karyotype analysis, multiplex ligation-dependent probe amplification, and whole exome sequencing. We also conducted a comprehensive literature review of previously reported cases.

resultsThe karyotype analysis and Multiplex ligation-dependent probe amplification results were normal. Whole exome sequencing revealed three novel de novo mutations, c.3712G > T (p.Glu1238*), c.3561 C > A (p.Cys1187*), and c.1069 C > T (p.Arg357*), in the KAT6A gene (NM_006766.5). The heterozygous variants were verified by Sanger sequencing and were not present in either parent.

conclusionsIn this study, we describe three cases of de novo KAT6A variants that were identified for the first time in Iran. Our results expand the understanding of the clinical features associated with Arboleda-Tham syndrome and validate the effectiveness of whole-exome sequencing to rapidly and accurately determine the etiology of such disorders. Furthermore, our literature review demonstrated close genotype-phenotype correlations associated with KAT6A and Arboleda-Tham syndrome.
