| 摘要 |
The present invention provides method(s) for measuring gene copy number (CN) of a given locus of interest, comprising 1 ) obtaining the CN value of the locus of interest, 2) obtaining the CN value or values of one or more CN-invariant locus reference(s) (CNILR) in the biological sample, where the CNILR is a locus which is locally CN-invariant or a locus with a minimal coefficient of variation, 3) obtaining the CN value or values of one or more CN-invariant and survival insignificant locus reference reference(s) (CNISILR) determined based on survival prediction analysis for a specific subgroup; and 4) normalizing the CN value of the locus of interest by the CN values of one or more CNISILRs if defined, otherwise normalizing the CN value of the locus of interest by the CN values of said one or more CNILRs. In one embodiment, the CNILRs or CNISILRs is one or more loci from the group consisting of XRCC5, AUTS2, EIF5, PARN, YEATS2 and FHL2. Also encompassed are kits and computer program or computer device for use in the methods of the invention. |
