后部-明显无脑回畸形-宽平脑桥延髓-中线交叉缺损综合征
Posterior-predominant lissencephaly-broad flat pons and medulla-midline crossing defects syndrome
ORPHA:572013疾病
定义 英文原文(暂无中文)
A rare genetic syndrome with a central nervous system malformation as a major feature, characterized by cortical malformations including posterior predominant lissencephaly and diffuse pachygyria, as well as midline crossing defects, thin corpus callosum, dysplastic hippocampi, narrowing of the brainstem with small pons and midbrain, widening of the medulla, and small cerebellum. Clinically, patients present global developmental delay, severe intellectual disability with poor or absent speech, axial hypotonia, and early-onset seizures, among others.
