Abstract

La présente invention concerne un procédé de détermination de variations du nombre de copies (VNC) d'une séquence d'intérêt dans un échantillon d'essai qui comprend un mélange d'acides nucléiques dont on sait ou suspecte qu'ils diffèrent en termes de quantité d'une ou plusieurs séquences d'intérêt. Le procédé propose une approche statistique qui tient compte de la variabilité accumulée provenant de la variabilité inter-chromosomique et inter-séquences. Le procédé est applicable à la détermination de VNC de toute aneuploïdie ftale, et des VNC dont on sait ou suspecte qu'elles sont associées à une variété d'affections médicales. Les VNC pouvant être déterminées selon le procédé de la présente invention comprennent les trisomies et les monosomies de l'un quelconque des chromosomes 1 à 22, X et Y, d'autres polysomies chromosomiques, et les délétions et/ou duplications de segments de l'un quelconque des chromosomes, qui peuvent être détectées par séquençage unique des acides nucléiques d'un échantillon. Toute aneuploïdie peut être déterminée à partir des informations de séquençage obtenues par séquençage unique des acides nucléiques d'un échantillon d'essai.
