Method of analyzing breast cancer susceptibility and resistance
A method of analyzing breast cancer susceptibility or resistance, comprising the steps of obtaining a DNA sample from a patient, genotyping the sample for the presence of the minor allele of single nucleotide polymorphisms rs6476643 or rs2182317, and correlating the identity of the allele with risk assessment data is disclosed.
1. A method of analyzing invasive breast cancer susceptibility or resistance, comprising the steps of
a) obtaining a DNA sample from a female human patient,
b) genotyping the sample for the presence of the minor allele of rs2182317 wherein G is substituted with T on the plus strand, and
c) analyzing invasive breast cancer susceptibility or resistance by correlating the identity of the allele with risk assessment data, wherein the presence of the minor allele of rs2182317 indicates a decreased risk of invasive breast cancer compared to a patient who does not have the minor allele of rs2182317 of step (b).
2. The method of claim 1 wherein the DNA sample is collected from mouthwash after the patient has rinsed his or her mouth with mouthwash.
3. The method of claim 1 wherein the patient is found heterozygous or homozygous for the minor allele at rs2182317.
4. The method of claim 3 wherein the correlation indicates that the patient has a 14% reduction in risk compared to a patient who does not have the minor allele at rs2182317.
5. The method of claim 1 , wherein step (b) further comprises genotyping the DNA sample for the presence of at least one minor allele selected from the group consisting of
