Analysis of BRCA1and BRCA2 large genomic rearrangements in Sri Lankan familial breast cancer patients and at risk individuals.
Article in BMC research notes, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundMajority of mutations found to date in the BRCA1/BRCA2 genes in breast and/or ovarian cancer families are point mutations or small insertions and deletions scattered over the coding sequence and splice junctions. Such mutations and sequence variants of BRCA1 and BRCA2 genes were previously identified in a group of Sri Lankan breast cancer patients. Large genomic rearrangements have been characterized in BRCA1 and BRCA2 genes in several populations but these have not been characterized in Sri Lankan breast cancer patients.
findingsA cohort of familial breast cancer patients (N = 57), at risk individuals (N = 25) and healthy controls (N = 23) were analyzed using multiplex ligation-dependent probe amplification method to detect BRCA1 and BRCA2 large genomic rearrangements. One familial breast cancer patient showed an ambiguous deletion in exon 6 of BRCA1 gene. Full sequencing of the ambiguous region was used to confirm MLPA results. Ambiguous deletion detected by MLPA was found to be a false positive result confirming that BRCA1 large genomic rearrangements were absent in the subjects studied. No BRCA2 rearrangement was also identified in the cohort.
conclusionThus this study demonstrates that BRCA1 and BRCA2 large genomic rearrangements are unlikely to make a significant contribution to aetiology of breast cancer in Sri Lanka.
