Pearson syndrome (PS) is a very rare and often fatal multisystem disease caused by deletions in mitochondrial DNA that result in sideroblastic anemia, vacuolization of marrow precursors, and pancreatic dysfunction. Spontaneous recovery from anemia is often observed within several years of diagnosis. We present the case of a 4-month-old male diagnosed with PS who experienced prolonged severe pancytopenia preceding the emergence of monosomy 7. Whole-exome sequencing identified two somatic mutations, including RUNX1 p.S100F that was previously reported as associated with myeloid malignancies. The molecular defects associated with PS may have the potential to progress to advanced myelodysplastic syndrome.
