A system for classifying thyroid nodule tissue as malignant or benign is provided that is based on the identification of sets of gene transcripts, which are characterized in that changes in expression of each gene transcript within a set of gene tran-scripts can be correlated to with either malignant or benign thyroid nodule disease. The thyroid classification system provides for sets of "thyroid classifying" target sequences and further provides for combinations of polynucleotide probes and primers derived there from. These combinations of polynucleotide probes can be provided in solution or as an array. The combination of probes and the arrays can be used for diagnosis. The invention further provides further methods of classifying thyroid nodule tissue.

L'invention porte sur un système pour la classification d'un tissu de nodule thyroïdien comme malin ou bénin, qui est fondé sur l'identification d'ensembles de produits de transcription de gènes, qui sont caractérisés en ce que des changements d'expression de chaque produit de transcription de gène à l'intérieur d'un ensemble de produits de transcription de gènes peuvent être corrélés avec une maladie à nodule thyroïdien soit maligne soit bénigne. Le système de classification thyroïdien fournit des ensembles de séquences cibles de « classification thyroïdienne » et fournit en outre des associations de sondes et amorces polynucléotidiques issues de celles-ci. Ces associations de sondes polynucléotidiques peuvent être fournies en solution ou sous forme d'une puce à ADN. L'association de sondes et les puces à ADN peuvent être utilisées pour un diagnostic. L'invention porte en outre sur d'autres procédés de classification de tissu de nodule thyroïdien.
