Lissencephaly With Cerebellar Hypoplasia Due To a New RELN Mutation.

Lissencephaly with cerebellar hypoplasia (LCH) is a rare variant form of lissencephaly, its distinctive neuroradiological phenotype being an important investigation clue regarding the potential involved genes, including variants in RELN gene. We report on a case of LCH whose clinical and neuroradiological features led to the identification of a homozygous pathogenic variant in RELN gene that has not been previously reported in the scientific literature.

Different relationships between epilepsy syndromes and autoimmune diseases.

Objective: Our objective was to study the relationship between epilepsy and autoimmune diseases in two different types of epilepsy: idiopathic generalized epilepsies (IGEs) and mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS). The contribution of the human leukocyte antigen (HLA) system to this relationship was analyzed.

Methods: Adult patients with IGEs and MTLE-HS at a tertiary epilepsy center were consecutively enrolled between January 2016 and December 2020.
