[Verse 1]
When truncus arteriosus shows its face
Every patient needs the genetic chase
Twenty-two q eleven point two deletion
FISH or microarray detection
[Chorus]
Test them all, no exceptions made
Twenty-two q deletion can't evade
FISH it out or microarray
Every truncus needs this DNA survey
[Verse 2]
Scan the chest with CT precision
Small thymus screams genetic mission
Shrinking shadows in the mediastine
Point to chromosomal magazine
[Chorus]
Test them all, no exceptions made
Twenty-two q deletion can't evade
FISH it out or microarray
Every truncus needs this DNA survey
[Bridge]
When the genetics come back positive
Three pathways open, each definitive
Immunology referral mandatory
Calcium levels need monitoring story
Speech and development assessment time
Catch the deficits before their prime
[Verse 3]
Thymic hypoplasia tells the tale
Genetic workup cannot fail
DiGeorge syndrome lurking near
Test results will make it clear
[Chorus]
Test them all, no exceptions made
Twenty-two q deletion can't evade
FISH it out or microarray
Every truncus needs this DNA survey
[Outro]
Every truncus arteriosus case
Genetic testing sets the pace
Twenty-two q deletion hunt
Comprehensive care upfront
