Abstract
Provided herein is technology for breast cancer screening and particularly, but not exclusively, to methods, compositions, and related uses for detecting the presence of breast cancer.
Claims20
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:
- (i) ATP6V1B1, LMX1B_A, BANK1, OTX1, MAX.chr11.14926602-14927148, UBTF, PRKCB, TRH_A, MPZ, DNM3_A, TRIM67, MAX.chr12.4273906-4274012, CALN1_A, ITPRIPL1, MAX.chr12.4273906-4274012, GYPC_B, MAX.chr5.42994866-42994936, OSR2_A, SCRT2_B, MAX.chr5.145725410-145725459, MAX.chr11.68622869-68622968, MAX.chr8.124173030-124173395, MAX.chr20.1784209-1784461, LOC100132891, BHLHE23_D, MAX.chr19.46379903-46380197, CHST2_B, MAX.chr5.77268672-77268725, C17orf64, EMX1_A, DSCR6, ITPRIPL1, IGF2BP3_B, DLX4, and ABLIM1;
