Difference of frequencies of unique SNP in CD44 intron 1 (CD44 Ex2+14 A>G) between Caucasian American (CA) and African-American (AA) females. Comparisons of percentages of subjects having the unique SNP in CD44 intron1 were made between: (A) CA female normal donors and AA female normal donors, (B) CA female breast cancer patients and AA breast cancer patients, (C) CA female normal donors and AA female normal donors, (D) CA female breast cancer patients and AA breast cancer patients when the patients were diagnosed with breast cancer. Fisher’s exact test was used to determine the statistical difference of unique SNP frequencies between two groups. Wilcoxon-Mann-Whitney test was used to determine the statistical differences of patient ages between two groups.
