17p13.3 deletion syndrome


Sunday 11 July 2010

The 17p13.3 deletion syndrome (or Miller-Dieker syndrome, MDS, MIM.247200) is characterized by lissencephaly, mental retardation and facial dysmorphism.

The phenotype is attributed to haploinsufficiency of two genes present in the minimal critical region of MDS:
- PAFAH1B1 (formerly referred to as LIS1)

Whereas isolated PAFAH1B1 deletion causes lissencephaly, YWHAE is a candidate for the dysmorphic phenotype associated with MDS.


- isolated lissencephaly
- Miller-Dieker syndrome
- dysmorphic facial features
