Miller-Dieker syndrome involves a severe type of lissencephaly, which is caused by defects in the lissencephaly gene (LIS1). We report the case of a female infant with der(17)t(12;17)(q24.33;p13.3)pat caused by an unbalanced segregation of the parental balanced translocation of 17p with other chromosomes. The proband presented with facial dysmorphism, arthrogryposis, and intrauterine growth ret...
AIMS/BACKGROUND To report a novel pattern of oculocerebral malformation related to the group of diseases characterised by cobblestone lissencephaly. METHODS By means of a case report with specialist descriptions of the novel neuropathological and ophthalmic pathology features. RESULTS The patient, born to healthy consanguineous parents, presented in the neonatal period with jaundice, convul...
We previously showed that mutations in LIS1 and DCX account for approximately 85% of patients with the classic form of lissencephaly (LIS). Some rare forms of LIS are associated with a disproportionately small cerebellum, referred to as lissencephaly with cerebellar hypoplasia (LCH). Tubulin alpha1A (TUBA1A), encoding a critical structural subunit of microtubules, has recently been implicated i...
X-linked lissencephaly and "double cortex" are allelic human disorders mapping to Xq22.3-Xq23 associated with arrest of migrating cerebral cortical neurons. We identified a novel 10 kb brain-specific cDNA interrupted by a balanced translocation in an XLIS patient that encodes a novel 40 kDa predicted protein named Doublecortin. Four double cortex/X-linked lissencephaly families and three sporad...
Mutations in the LIS1 gene cause lissencephaly, a human neuronal migration disorder. LIS1 binds dynein and the dynein-associated proteins Nde1 (formerly known as NudE), Ndel1 (formerly known as NUDEL), and CLIP-170, as well as the catalytic alpha dimers of brain cytosolic platelet activating factor acetylhydrolase (PAF-AH). The mechanism coupling the two diverse regulatory pathways remains unkn...
INTRODUCTION X-linked lissencephaly with ambiguous genitalia (XLAG) is a recently described genetic disorder caused by mutation in the aristaless-related homeobox (ARX) gene (Xp22.13). Patients present with lissencephaly, agenesis of the corpus callosum, refractory epilepsy of neonatal onset, acquired microcephaly and male genotype with ambiguous genitalia. CASE REPORT Second child born to he...
