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

Germline pathogenic variants within the highly conserved exonuclease domain of the POLD1 gene predisposes to colorectal (CRC) and endometrial (EC) cancers. Tumours with POLD1-deficiency demonstrate unique genomic features including hypermutation and tumour mutational signatures (TMS) SBS10c, SBS10d and SBS20. The classification of variants within POLD1 remains challenging. The utility of incorporating tumour hypermutation status and TMS profiles into POLD1 gene-specific variant classification guidelines developed by ClinGen-InSiGHT remains to be established. We report a family with eight members heterozygous for the germline POLD1 c.1420C > A (p.Leu474Ile) variant. This variant resides within the exonuclease domain, is absent in gnomADv4.1 and is classified as a variant of uncertain clinical significance. Formalin-fixed paraffin embedded tissue and matched blood-derived DNA from person 001 (EC, 1 adenoma, 2 sessile serrated lesions), and two cousins, 009 (EC, 3 adenomas), and 010 (breast cancer, EC, CRC, 4 adenomas, 2 sessile serrated lesions and 1 traditional serrated adenoma) were tested using a custom multigene panel to determine tumour mutational burden (TMB) and TMS. All three ECs demonstrated characteristics of POLD1-deficiency namely hypermutated TMB and predominance of SBS10d. The CRC, 62.8% of the adenomas and 60% of the serrated polyps demonstrated SBS10c as the dominant TMS. EC, CRC, breast and multiple polyps from three family members heterozygous for the germline POLD1 c.1420C > A variant demonstrated hypermutation and SBS10c and SBS10d TMS, genomic features associated with defective POLD1. Somatic TMB and TMS profiling of multiple independent lesions demonstrated utility for identifying POLD1-deficiency suggesting this approach can support variant classification for POLD1.
