All 5q deletions in our 10 cases and in another study of 12 MDS cases with an isolated 5q deletion by Evers C et al. [20] involved the loss of the RPS14 gene at 5q33.1, which support the causal role of RPS14 haploinsufficiency and were specified in the diagnostic reports [21]. This evidence concerns the gene RPS14 and myelodysplastic syndrome.
