BECN1 and cancer: Many genes were frequently altered in OV, and HAPTRIG ranked known biologically impactful genes (for example, BRCA1, TP53, BECN1 and CASP3) as most altered for OV (Fig. 3b, full OV networks in Supplementary Fig. 4), as well as some genes uncommonly associated with cancer (for example, CTSD for lysosomal function and PEX5 for peroxisomal function, full summary in Supplementary Table 2).
