NALF2 and cancer: Forest plot analysis of overall survival (OS) demonstrated that high FAM155B expression was associated with poor prognosis in several cancers, with the most significant associations observed in BRCA (HR = 1.120, p = 0.023), KIRP (HR = 1.123, p = 0.017), LAML (HR = 1.197, p = 0.023), and PRAD (HR = 1.483, p < 0.001) (Figure 4A).
