Patent ID: 7517650

Claim:
A method of determining an increased risk of having or developing breast cancer in a human female aged younger than 41, which comprises a) obtaining a nucleic acid sample from the human female aged younger than 41; b) determining the nucleotide present at position 101 of SEQ ID NO: 9 (SMBC — 013); the nucleotide present at position 101 of SEQ ID NO: 15 (SMBC — 025); the nucleotide present at position 101 of SEQ ID NO: 18 (SMBC — 034); and the nucleotide present at position 101 of SEQ ID NO: 28 (SMBC — 062); and c) determining that the female has an increased risk of having breast cancer or developing breast cancer when a TT or TO is determined at SMBC — 013; TT is determined at SMBC — 25; TT is determined at SMBC — 034; and AA is determined at SMBC — 062 compared to when a different genotype pattern is determined to be present.
