Shwachman‐Diamond syndrome with clonal interstitial deletion of the long arm of chromosome 20 in bone marrow: haematological features, prognosis and genomic instability

Abstract excerpt

In Shwachman-Diamond syndrome (SDS), deletion of the long arm of chromosome 20, del(20)(q), often acquired in bone marrow (BM), may imply a lower risk of developing myelodysplastic syndrome/acute myeloid leukaemia (MDS/AML), due to the loss of the EIF6 gene. The genes L3MBTL1 and SGK2, also on chromosome 20, are in a cluster of imprinted genes, and their loss implies dysregulation of BM function. We report here...
