Embodiment 1
[0053] Embodiment 1 Using the method and system provided by the present invention to obtain the age of male individuals in the Chinese population
[0054] Hereinafter, a male individual is taken as an example to illustrate the implementation process of the solution of the present invention.
[0055] 1. Extract the DNA of the individual to be tested as a template
[0056] The DNA solution of the above-mentioned one male individual was extracted separately using a DNA blood midi kit (QIAGEN, Hilden, Germany).
[0057] 2. Perform PCR amplification reaction on the extracted DNA template
[0058] 2.1. Primer pool configuration
[0059] The configuration of the amplification primer pool, wherein the amplification primer set is 9 pairs of amplification primers corresponding to the 9 CpG sites, each pair of amplification primers can amplify the DNA to be detected including its corresponding CpG site; in this embodiment, preferably, the amplification primer set of the 9 CpG sites is...
Embodiment 2
[0083] Using the same method and system as in Example 1, the ages of all 65 unrelated Chinese male individuals of different ages were estimated using the same steps. To test the accuracy of the above system, the results are shown in the following table:
[0084]
[0085] The age error range of male individuals obtained by the method of this embodiment is about 2-5 years old, indicating that the method and system of the present invention can be used to estimate the age of individuals aged 15 to 75, and has good accuracy, and can provide data for case detection support.
