TERT c.3150 G > C (p.K1050N): a founder Ashkenazi Jewish variant associated with telomere biology disorders.

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
Pathogenic germline variants in telomerase (TERT) cause telomere biology disorders (TBDs) and are associated with bone marrow failure, pulmonary fibrosis, and other complications. TERT c.3150 G > C (p.K1050N) is frequent in the Ashkenazi Jewish (ASH) population and has been identified in ASH families with TBDs. Whole-genome sequencing of 96 p.K1050N heterozygotes from the UK Biobank and All of Us databases revealed a shared haplotype block, supporting a founder effect. Analyses of 15 additional p.K1050N cases validated this haplotype and identified mitochondrial and Y-STR haplogroups consistent with ASH ancestry. Clinical assessments showed that p.K1050N contributes to TBD phenotypes and shortened telomeres, while population data suggest incomplete penetrance. p.K1050N reduces telomerase activity and processivity, and decreases PCNA expression and BrdU incorporation, impairing cell proliferation. Our findings establish TERT p.K1050N as an ASH founder variant associated with TBDs, underscoring the need for genetic screening and long-term clinical studies.
