A 12 Mb deletion of 6p24.1-->pter in an 18-gestational-week fetus with orofacial clefting, the Dandy-Walker malformation and bilateral multicystic kidneys.

We report an 18-gestational-week fetus with oligohydramnios, orofacial clefting, bilateral multicystic kidneys and the Dandy-Walker malformation. Characteristic craniofacial features include a turricephalic prominent forehead, hypertelorism, low-set ears, a flat nasal bridge, mid-face hypoplasia, bilateral cleft lip and palate, and a thick nuchal fold. Array-comparative genomic hybridization (CGH) analysis demonstrated a 12Mb deletion of 6p24.1-->pter.
