The syndrome is caused by an interstitial deletion (a deletion that does not involve the ends of a chromosome) encompassing bands 23.1 to 23.2 on the long (q) arm of chromosome 17. Two transcription factors, TBX2 and TBX4, which belong to a family of genes implicated in a variety of developmental pathways including those of heart and limbs, are found within this 2.2Mb region. This suggests that they may play a part in the symptoms seen in this condition.
