High Resolution Melting Analysis is Very Useful to Identify BRCA1 c.4964_4982del19 (rs80359876) Founder Calabrian Pathogenic Variant on Peripheral Blood and Buccal Swab DNA.
Article in Molecular diagnosis & therapy, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
introductionDetection of pathogenic variants in hereditary breast and ovarian cancer-related breast cancer type 1 and type 2 susceptibility proteins (BRCA1/2) genes is an effective strategy in cancer prevention and treatment. Some ethnic and geographical regions show different BRCA1/2 mutation spectrum and prevalence. In Italy, elucidation of founder effect in BRCA1/2 genes can have an impact on the management of hereditary cancer families on a healthcare system level, making genetic testing more affordable and cost effective in certain regions.
methodsThe purpose of this paper is to develop a rapid, low-cost, high-throughput single-tube technology for genotyping the Italian founder mutation c.4964_4982del19 (rs80359876) in the BRCA1 gene, starting from peripheral blood and/or buccal swab DNA.
resultsHeterozygote samples for c.4964_4982del19 variant were easily and unambiguously identified by the altered shape of the melting curves and were clearly distinguished by a change in melting temperature that differed by approximately 5 °C. The same results were obtained both with DNA from peripheral blood than buccal swab.
conclusionsWe provide evidence about application of high-resolution melting analysis (HRMA) in unambiguously genotyping of the founder BRCA1 c.4964_4982del19 variant (rs80359876) in individuals from the Calabria region of Italy. In fact, HRMA was confirmed to be particularly suitable for the identification of BRCA1 c.4964_4982del19 variant, making this approach useful in clinical molecular diagnostics.
