According to this, unfavorable prognosis for BC relapse (i.e. higher relative expression levels correlating with increased risk for relapse) of Ankyrin repeat domain-containing protein 36 C (ANKRD36C; HR = 2.12), Forkhead box protein D2 (FOXD2; HR = 3.11) collagen alpha-1 chains I (HR = 1.94), III (HR = 1.77), IV (HR = 2.33), VI (HR = 2.65), XIV (HR = 3.15), collagen alpha-3 chain IV (HR = 8.75) and collagen alpha-4 chain IV (HR = 3.53) is in line with lower 5-year overall survival based on the TCGA gene expression data. This evidence concerns the gene ANKRD36C and breast cancer.
