• patterning of the second pharyngeal arch is normal despite the failure of neural crest cells to migrate into the arch
• neural crest cells emanating from r4 fail to migrate properly and populate the second pharyngeal arch
• however, neural crest cell differentiation, proliferation and apoptosis are normal
• neural crest cells fail to delaminate from r4
