Claims1

Dependent claims

A method, comprising:

measuring a methylation level for one or more genes in a biological sample of a human individual through
treating genomic DNA in the biological sample with a reagent that modifies DNA in a methylation-specific manner;
amplifying the treated genomic DNA using a set of primers for the selected one or more genes;
and
determining the methylation level of the one or more genes by polymerase chain reaction, nucleic acid sequencing, mass spectrometry, methylation-specific nuclease, mass-based separation, and target capture;
wherein the one or more genes comprises a chromosomal region having an annotation that is selected from one of the following groups:
