Integration Of Hi-C And Nanopore Sequencing For Structural Variant Analysis In Aml With A Complex Karyotype: (Chromothripsis)(2)

Background. Acute myeloid leukemia (AML) with a complex karyotype (CK-AML) is an AML subtype with a still dismal outcome despite recent therapeutic advances. The prognosis is even worse when the underlying structural variants (SVs) lead to an extremely complex pattern of rearrangements, called chromothripsis, with a median overall survival of only 120 days. Except for the presence of inactivating TP53 aberrations in about 70% of all AML-CK cases, the pathogenesis is poorly understood. To gain novel insights into the molecular mechanisms underlying CK-AML reliable high precision SV delineation is needed, which so far has been a major limitation in cancer research.
