Somatic mutations show no clear association with red blood cell or human leukocyte antigen alloimmunization in de novo or therapy-related myelodysplastic syndrome.

While JAK2 specific mutations were enriched among RBC alloimmunized patients, this association failed to reach statistical significance in our single-center cohort. Further study using larger patient cohorts is warranted. Overall, this cohort of MDS patients had very similar RBC alloimmunization prevalence and anti-RBC antibody specificities as other recent literature. Our data reinforce the finding that MDS patients are at greater risk for alloimmunization and support the use of extended phenotype matching for these at-risk patients.
