Unraveling mutagenic processes influencing the tumor mutational patterns of individuals with constitutional mismatch repair deficiency.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Constitutional mismatch repair deficiency (CMMRD), caused by bi-allelic germline variants in mismatch repair (MMR) genes, is associated with high cancer incidence early in life. A better understanding of mutational processes driving sequential CMMRD tumors can advance optimal treatment. Here, we describe a genomic characterization on a representative collection of CMMRD-associated tumors consisting of 41 tumors from 17 individuals. Mutational patterns in these tumors appear to be influenced by multiple factors, including the affected MMR gene and tumor type. Somatic polymerase proofreading mutations, commonly present in brain tumors, are also found in a T-cell lymphoblastic lymphoma displaying associated mutational patterns. We show prominent mutational patterns in two second primary hematological malignancies after temozolomide treatment. Furthermore, an indel signature, characterized by one-base pair cytosine insertions in cytosine homopolymers, is found in 54% of tumors. In conclusion, analysis of sequential CMMRD tumors reveals diverse mutational patterns influenced by the affected MMR gene, tumor type and treatment history.
