text: Yo, check it out, listen up, I got a story to tell,
  'Bout a 3-year-old kid, Filipino-American as well.
  He had them symptoms, recurrent fever on the rise,
  Splenomegaly, anemia, and thrombocytopenia in his eyes.
  
  His hemoglobin F level was off the charts, 76.9 percent,
  Reticulocyte count was high, yo, you know what I meant?
  Erythroblasts in his blood, yeah, they were there,
  Microcytic erythrocytes, but ferritin levels were fair.
  
  Bone marrow looked clean, no blast cells to be seen,
  But as time went on, things got worse, if you know what I mean.
  Anemia got worse, leukocytosis took its toll,
  Thrombocytopenia hit hard, like a punch to the soul.
  
  Blasts increased in his marrow, a mass in his chest,
  Liver, spleen, lymph nodes, all infiltrated, no rest.
  Diagnosis came through, juvenile myelomonocytic leukemia,
  JMML was the name, a condition that was severe.
  
  Hb F analysis revealed a ratio, Ggamma/Agamma, 2.2 in sight,
  Fit the range for JMML, confirming it was right.
  Globin synthesis study showed a ratio, alpha/non-alpha, 2.24,
  Severe homozygous beta thalassemia, knockin' at the door.
  
  Southern blot analysis done, DNA from patient and kin,
  No apparent issues with beta-globin gene, nothin' within.
  That elevated Hb F, Cooley's anemia-like it seemed,
  Part of the hematologic phenotype, a twist in the theme.
  
  So there you have it, the tale of this young warrior's fight,
  Through fevers, anemia, and a darkness that felt like night.
  But with knowledge and research, we strive to understand,
  And one day find a cure, lend a helping hand.
