Objective: To study whether the occurrence and type of placental lesions vary according to the time of onset of COVID-19 in pregnant women.
Design: Case-control study.
Setting: Departments of Gynaecology-Obstetrics and Pathology, Strasbourg University Hospital, France.
Background: The dystonias are a heterogeneous group of hyperkinetic disorders characterized by sustained or intermittent muscle contractions that cause abnormal movements and/or postures. Although more than 200 causal genes are known, many cases of primary dystonia have no clear genetic cause.
Objectives: To identify the causal gene in a consanguineous family with three siblings affected by a complex persistent generalized dystonia, generalized epilepsy, and mild intellectual disability.
