Mosaicism of an ELANE Mutation in an Asymptomatic Mother.
Article in Journal of clinical immunology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeWe report normal neutrophil count in a mother, who carries the same ELANE mutation as her daughter with severe congenital neutropenia. We hypothesized that the mother possessed wild- and mutant-type clones and the wild-type clones could generate neutrophils, whereas the mutant clones could not.
methodsWe confirmed mutant variant ratio by sequence signals and measured the frequency of the mutant allele by subcloning in various cell types. We established the ELANE-mutated and non-mutated induced pluripotent stem cells (iPSCs) from the mother's T cells and compared granulopoiesis between these iPSCs.
resultsIn the sequence analysis of isolated peripheral blood (PB), nail and hair, the mutant variant was detected in approximately 40-60% of lymphocytes, monocytes, hematopoietic progenitor cells, and hair as well as in a small percentage of nail, but in none of the neutrophils. In the subcloning analysis of extracted DNA from CD3
conclusionsThese observations strongly suggest that mutant-carrying neutrophils did not appear in the mother's PB because mutated clones could not differentiate into neutrophils. The mother's normal hematological phenotype could be explained by the perseverance of normal, non-mutated granulopoiesis.
