Interestingly, several of these genes were present on 8q, a recurrently amplified region in MBCs and TNBCs, including COX6C, YWHAZ, and ATP6V1C1 on 8q22 (Fig. 4a) and RAD21, NDUFB9, and MYC on 8q24 (Fig. 4b). The gene discussed is NDUFB9; the disease is maternal uniparental disomy of chromosome 20.
