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

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition with a strong genetic basis. Most genetic studies on ASD emphasize de novo mutations, while inherited rare variants remain understudied. We hypothesize that subtle, inherited ASD-related traits accumulate across generations and clinically manifest as ASD in offspring. To investigate this, we extracted inherited variations from trio-based Whole Exome Sequences (WES) of 23 simplex ASD families (accession number PRJNA1071313 and PRJNA1072259). Data was processed in BWA, GATK and VarScan. Variants were annotated, filtered for functional impact, and scored using a 'weighted scoring' approach based on intolerance to genetic alterations. Overall 751 'weighted-genes' with evolutionary and neuronal functions hosting deleterious inherited variations were functionally annotated for ASD-linked behaviours and comorbidities. We found 149 (20%) genes enriched for core ASD-behaviours like social-interaction and restrictive repetitive behaviours (RRB), 200 genes (26.6%) for associated-behaviours like hyperactivity, communication, intelligence and mood and 225 genes displayed neuronal-functions (p = 3.799E-20). Importantly, 62% of RRB genes displayed sensory functions and 71.43% of genes associated to social interaction deficits were also linked to seizures. Brain tissue expression analysis of all 751 genes revealed 95 prenatally and 195 postnatally upregulated genes were enriched with neurodevelopmental and neurotransmission functions, respectively; protein-protein-interactions suggested genes BUB1, HMGA2, HDAC2, KALRN, SORL1, IGF2, FASN, WFS1 as promising new-candidates for ASD. In our ASD cohort, inherited variations in genes regulating sensory function and neurodevelopment were also RRB producing genes- supporting a multigenic, subdued but additive genetic load being passed down from unrelated parents to their offsprings- promising an underexplored avenue for autism genetic research.
