Abstract

In this report we described the case of a BRCA1/2 (BRCA) molecular testing performed on tumor sample in a High Grade Serous Ovarian Cancer (HGSOC) patient with two different Next Generation Tumor Sequencing (NGTS) pipelines. The two clinical reports leaded to apparently different BRCA status, providing important foods for thought. After NGTS, the gene sequencing information (i.e., reads) are aligned to the reference gene sequences obtained from public databases, in order to provide an uniform nomenclature for unambiguous variant designation. However, the criteria adopted for variant reporting in tissue test are not always univocal. Particularly, this is the case of rare and unclassified BRCA variants for which the molecular evaluation may be a relevant challenge. Here we described a BRCA1 unclassified variant that may be re-evaluated in the context of alternative BRCA1 transcripts due to its different biological effect. We underlined that an in-depth knowledge of BRCA testing is mandatory for its appropriate use.
