SFRP4 and cancer: Normal and cancer datasets were visually investigated using IGV for the following genes: WIF1, SFRP4, WNT2, WNT3, WNT5A, CRNDE, UCA1, HOTAIR, and CD82. Ten SNPs (Table 4) were found in five of the genes: WIF1, SFRP4, WNT5A, UCA1, and CD82. No consistent abnormalities were found in the others.
