Title: Can a newborn be born with leukeamia?
Post by: thedoc on 11/12/2012 19:05:09
A baby died at 3 months of age with acute leukaemia, but the doctor said the baby was born with it.  Could that be the case?

We answered this question on the show...

 Mark D. -   Yes, so what we now know is that many of the infantile leukaemias actually had their origins in utero. 
So, when we go and have a look at whenever any baby is born - and you would’ve seen this with your own kids - you have a heel ***** test and this is taken away to be tested for a number of common genetic diseases.  When you go back and have a look at these samples [from a leukaemia patient], for instance these chromosomal translocations, these abnormal fusion genes that drive leukaemia, are they present when the baby is actually born?  In a number of cases, the answer is yes.  So, this abnormal genetic event is not inherited, but for some reason, happens while the baby is in utero.
