Systems and methods for determining a treatment course of action
The present disclosure relates to methods of determining a treatment course of action. In particular, the present disclosure relates to mutations in the gene encoding estrogen receptor and their association with responsiveness to estrogen therapies for cancer.
1. A kit, comprising:
nucleic acid molecules for detecting the presence of two or more variant ESR1 nucleic acids, wherein said variant ESR1 nucleic acids encode a ESR1 polypeptide comprising a p.Leu536Gln variant and one or more variants selected from the group consisting of p.Tyr537Ser, p.Tyr537Asn, and p.Tyr537Cys, wherein said nucleic acid molecules consist of nucleic acid primers that amplify at least the portion of said variant ESR1 nucleic acid comprising said variant and nucleic acid probes that each specifically hybridize to the portion of said variant ESR1 nucleic acid comprising said variant but not a wild type ESR1 gene, wherein said primers and probes are at least 10 nucleotides in length, and wherein said probes comprise a detectable label.
2. The kit of claim 1 , wherein said label is a fluorescent label.
3. The kit of claim 1 , wherein said pair of nucleic acid primers and said nucleic acid probe are at least 20 nucleotides in length.
4. A kit, comprising:
nucleic acid molecules for detecting the presence of two or more variant ESR1 nucleic acids, wherein said variant ESR1 nucleic acids encode a ESR1 polypeptide comprising a p.Leu536Gln variant and one or more variants selected from the group consisting of p.Tyr537Ser, p.Tyr537Asn, and p.Tyr537Cys, wherein said nucleic acid molecules consist of pairs of primers, wherein one primer of each of said pairs specifically hybridizes to the portion of said variant ESR1 nucleic acid comprising said variant but not to a wild type ESR1 gene, and a probe that specifically hybridizes to an amplicon resulting from an amplification reaction using said pairs of nucleic acid primers, wherein said primers and probe are at least 10 nucleotides in length, and wherein said probe comprises a detectable label.
5. The kit of claim 4 , wherein said pair of nucleic acid primers and said nucleic acid probe are at least 20 nucleotides in length.
6. The kit of claim 4 , wherein said label is a fluorescent label.
