[Verse 1]
When truncus arteriosus shows its face
There's a test we need in every case
Twenty-two q eleven point two deletion
Start the genetic investigation
Don't wait or wonder, don't delay
FISH or microarray today
Every patient needs this screen
Most important test you've ever seen
[Chorus]
Test them all, test them all
Twenty-two q eleven call
FISH or microarray shine
Catch the deletion every time
Small thymus on the CT scan
Genetic workup, that's the plan
Test them all, don't let it fall
Twenty-two q deletion call
[Verse 2]
CT chest reveals a tiny thymus
This small clue should really remind us
When the shadow's not the normal size
Genetic testing's what we advise
The deletion hides in chromosome bands
But modern testing helps us understand
Fluorescent probes will light the way
Microarrays save the day
[Chorus]
Test them all, test them all
Twenty-two q eleven call
FISH or microarray shine
Catch the deletion every time
Small thymus on the CT scan
Genetic workup, that's the plan
Test them all, don't let it fall
Twenty-two q deletion call
[Bridge]
If positive results appear
Three referrals you hold dear
Immunology first in line
Calcium levels monitor fine
Speech and development assess
Cover all the bases, nothing less
[Verse 3]
When the test comes back positive
Three pathways now you have to give
Immune system needs attention
Calcium drops need prevention
Speech delays and learning too
Developmental check is overdue
Comprehensive care's the key
For twenty-two q deletion, you see
[Chorus]
Test them all, test them all
Twenty-two q eleven call
FISH or microarray shine
Catch the deletion every time
Small thymus on the CT scan
Genetic workup, that's the plan
Test them all, don't let it fall
Twenty-two q deletion call
[Outro]
Every truncus patient screened
Best outcomes can be achieved
Twenty-two q deletion found
Comprehensive care all around
