Haploinsufficiency of TBX1, encoding a Tbox transcription factor, is largely responsible for the physical malformations in velo-cardio-facial /DiGeorge /22q11.2 deletion syndrome (22q11DS) patients. Cardiovascular malformations in these patients are highly variable, raising the question as to whethe
Prenatal diagnosis of the DiGeorge/velo-cardio-facial syndrome has become possible since it was recognized that this syndrome is caused by a submicroscopic deletion in chromosome 22q11. In a sporadic patient presenting a conotruncal heart defect and polyhydramnios, the del 22q11 was made prenatally
