Título: | Probability distribution of copy number alterations along the genome: an algorithm to distinguish different tumour profiles | Autor: | Esteves, Luísa Caramelo, Francisco Ribeiro, Ilda Patrícia Carreira, Isabel M. Melo, Joana Barbosa de |

High resolution microarray-based genome-wide technologies have been widely used to detect CNAs, generating complex datasets that require further steps to allow for the determination of meaningful results. In this work, we propose a methodology to determine common regions of CNAs from these datasets, that in turn are used to infer the probability distribution of disease profiles in the population. This methodology was validated using simulated data and assessed using real data from Head and Neck Squamous Cell Carcinoma and Lung Adenocarcinoma, from the TCGA platform. Probability distribution profiles were produced allowing for the distinction between different phenotypic groups established within that cohort. This method may be used to distinguish between groups in the diseased population, within well-established degrees of confidence. The application of such methods may be of greater value in the clinical context both as a diagnostic or prognostic tool and, even as a useful way for helping to establish the most adequate treatment and care plans. | URI: | https://hdl.handle.net/10316/106713 | ISSN: | 2045-2322 | DOI: | 10.1038/s41598-020-71859-1 | Direitos: | openAccess |
