Genetic Predisposition to Therapy-Related Myeloid Neoplasm By Rare, Deleterious Germline Variants in DNA Repair Pathway and Myeloid Driver Genes

Therapy-related myeloid neoplasm (t-MN) is considered to be a direct stochastic complication of chemotherapy and/or radiotherapy for primary cancer or autoimmune diseases. However, genetic predisposition is reported in 8-12% of sporadic adult cancer patients [Lu et al Nature Communication 2015 and Huang et al Cell 2018]. Similarly, genetic predispositions to t-MN have also been reported in limited single institute studies of small numbers of patients [Churpek et al Cancer 2016].
