Abstract

L'invention concerne des procédés, des systèmes et un logiciel permettant de valider une variation d'un nombre de copies, de valider une variante de séquence somatique, et/ou de déterminer des estimations de fractions tumorales circulantes à l'aide de lectures de séquences sur cible et hors cible chez un sujet de test. Une annotation d'état de nombre de copies d'un segment génomique est validée par application d'un premier ensemble de données à une pluralité de filtres comprenant un filtre de mesure de rapport de séquence de niveau binaire de tendance centrale, un filtre de confiance, et un filtre de mesure de rapport de séquence de niveau binaire de tendance centrale-plus-écart. Une variante de séquence somatique est validée par comparaison d'un compte de fragments d'allèle variant d'une variante de séquence somatique candidate d'un locus respectif, par rapport à un seuil de compte de variantes dynamiques du locus dans une séquence de référence respective. Une fraction tumorale circulante est estimée sur la base d'une mesure d'ajustement entre des rapports de segment génomique-couverture de niveau et des états de copie entière sur une pluralité de fractions tumorales en circulation simulées.
