The results for colorectal cancer show positive correlation among mRNA of all analyzed genes, although only the following were statistically significant: CD44 correlated positively with HAS2 (p = 0.024), HYAL1 (p = 0.012), BRCA1 (p = 0.007) and BRCA2 (p = 0.012); HAS2 correlated positively with HAS3 (p = 0.017), HYAL1 (p = 0.024) and BRCA1 (p = 0.024); HAS3 correlated positively with HYAL1 (0.033) and BRCA1 (0.017); HYAL1 correlated positively with HYAL2 (p = 0.012) and BRCA1 (p = 0.007); BRCA1 correlated positively with BRCA2 (p = 0.007). The gene discussed is BRCA1; the disease is colorectal cancer.
