AD MR 13 - variable neuronal migration defects - variable features include seizures and mild dysmorphic features. Willemsen et al, 2012 - 51 year old women, developed generalised seizures aged 3 - de novo het missense variant. Poirer et al, 2013 - 8 unrelated patients with MR - all but 1 had seizures - most early onset - 8 diff de novo het mutatons.

Comment on list classification: Updated rating from Amber to Green: Green review by Zornitza and sufficient unrelated cases (7 sporadic cases plus two brothers and their mother) in PMID:23603762 of patients with epilepsy for inclusion on panel.Created: 26 Nov 2018, 10:20 a.m.
PMID:23603762 (Poirier et al. 2013) analysed 16 patients with malformations of cortical development (MCD), and found variants in 4 genes including DYNC1H1. Epileptic symptoms were reported in 8 cases of patients with DYNC1H1 variants (7 sporadic cases and two brothers and their mother in family 346). An additional patient, P398, did not show epilepsy. Epileptic symptoms in patients included Early-onset epilepsy, late-onset epilepsy, Lennox Gastaut and Focal seizures.Created: 26 Nov 2018, 10:17 a.m.
