Green List (high evidence)

In a study of myelodysplastic syndrome (MDS) acute myeloid leukemia (AML) patients, Rio-Machin et al (PMID: 32098966) reported the association between helicase DHX34 variants and MDS and AML. The authors report four different DHX34 variants in four unrelated families. Functional studies of the four DHX34 variants revealed they compromised nonsense-mediated RNA decay activity, demonstrated by the failure to promote phosphorylation of UPF1 (PMID: 320989660).
