Frequency of unique SNP in CD44 intron 1 (CD44 Ex2+14 A>G) in female normal donors and breast cancer patients. Comparisons of percentages of individuals having the unique SNP in CD44 intron1 were made between: (A) total normal donors versus breast cancer patients, (B) Caucasian American (CA) normal donors versus CA breast cancer patients, (C) African-American (AA) normal donors and AA breast cancer patients, (D) non-unique SNP carriers versus unique SNP carriers 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.
