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

Alkylglycerol monooxygenase (AGMO) is the only enzyme known to cleave the O-alkyl bonds of ether lipids (alkylglycerols) which are essential components of cell membranes. A homozygous frameshift variant [p.(Glu324LysfsTer12)] in AGMO has recently been reported in two male siblings with syndromic microcephaly. In this study, we identified rare nonsense, in frame deletion, and missense biallelic variants in AGMO in two unrelated individuals with neurodevelopmental disabilities. We assessed the activity of seven disease associated AGMO variants including the four variants identified in our two affected individuals expressed in human embryonic kidney (HEK293T) cells. We demonstrated significantly diminished enzyme activity for all disease-associated variants, supporting the mechanism as decreased AGMO activity. Future mechanistic studies are necessary to understand how decreased AGMO activity leads to the neurologic manifestations.
