Mutational spectrum and profile of breast and ovarian cancer patients in Saudi Arabia's western region: single center experience.
Article in Discover oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundThe incidence of breast cancer (BC) and ovarian cancer (OC) has increased in Saudi Arabia. The western region of Saudi Arabia presents a unique population with distinct genetic backgrounds, making it vital to investigate the prevalence of BC/OC-associated gene mutations in this area. This study aimed to determine the prevalence and mutational profiles of BC and/or OC predisposing genes in the western region of Saudi Arabia, and to characterize the associated phenotypes in individuals carrying these mutations.
methodsWe employed next-generation sequencing (NGS) to identify the mutational spectra of 209 Saudi Arabian patients with BC and/or OC from the Western region.
results51/209 (24.4%) patients had a mutation in one of the BC/OC predisposing genes. Overall, 34, 10, and 7 PV/LPV were identified in BRCA1, BRCA2, and other genes, respectively. Mutations in BRCA1 were predominant and strongly related to high-grade, triple-negative BC. BRCA1 NM_007294.4:c.1140dup p.(Lys381Glufs*3), NM_007294.4:c.5095C > T p.(Arg1699Trp), NM_007294.4:c.4986 + 6 T > C (p.?), NM_007294.4:c.5251C > T p.(Arg1751*), and NM_007294.4:c.5067_5074 + 1del p.(Met1689Ilefs*3) were recurrent with NM_007294.4:c.3217_3218del p.(Gly1073*), NM_007294.4:c.5067_5074 + 1del p.(Met1689Ilefs*3), and NM_007294.4:c.5234del p.(Asn1745Thrfs*20) being novel. The combined frequency of recurrent mutations in BRCA1 was 42%. Concerning BRCA2, we identified a recurrent variant NM_000059.4:c.7480C > T p.(Arg2494*) and two novel variants NM_000059.4:c.643del p.(Glu215Lysfs*15) and NM_000059.4: EXon1-8del.
conclusionIn our study, we identified a high prevalence of BRCA1/2 variants in the western region of Saudi Arabia, offering novel and important insights specific to this area. We also identified other gene variants, though their impact remains unclear due to the limited sample size. This work represents an important first step in understanding the genetic factors contributing to breast and ovarian cancer in the Western region. It underscores the urgent need for larger studies to comprehensively explore the genetic landscape and better understand how these variants influence cancer risk in this population.
