Classical lissencephaly associated with dolichocephaly, hair and nail defect.

ABSTRACT

We report on an 1-day-old boy with classical lissencephaly (grade 1, according to Kato and Dobyns, 2003) associated with an extended phenotype, including dolichocephaly, and hair and nail defects. The diagnosis of lissencephaly was made in utero, allowing the rapid characterization of the phenotype at birth. Because previously reported cases were not associated with the features described in our proband, they might represent a newly identified condition.
