Abnormal <scp>RH</scp> antigen expression in myeloid malignancies with <scp> <i>MPL</i> </scp> mutation, <scp> <i>CSF3R</i> </scp> mutation, or 1p deletion: Evidence of two distinct mechanisms

CN-LOH of chromosome 1p, resulting in homozygosity for the MPL mutation, has been previously described in the literature. However, we report here for the first time a link between CN-LOH of chromosome 1p (resulting in homozygosity for the CSF3R mutation) or chromosome 1p deletion and the presence of RH phenotype abnormalities. Furthermore, no alloimmunization was observed despite increased transfusion requirements.

Abstract

CN-LOH of chromosome 1p, resulting in homozygosity for the MPL mutation, has been previously described in the literature. However, we report here for the first time a link between CN-LOH of chromosome 1p (resulting in homozygosity for the CSF3R mutation) or chromosome 1p deletion and the presence of RH phenotype abnormalities. Furthermore, no alloimmunization was observed despite increased transfusion requirements.
