Background: We investigated a family that presented with an infantile-onset chorea-predominant movement disorder, negative for NKX2-1, ADCY5, and PDE10A mutations. Methods: Phenotypic characterization and trio whole-exome sequencing was carried out in the family. Results: We identified a homozygous mutation affecting the GAF-B domain of the...

Objective: The primary objective of this research was to characterize the movement disorders associated with FOXG1 mutations. Methods: We identified patients with FOXG1 mutations who were referred to either a tertiary movement disorder clinic or tertiary epilepsy service and retrospectively reviewed medical records, clinical investigations,...

Primary familial brain calcification (PFBC) is a rare neurodegenerative disorder characterized by a combination of neurological, psychiatric, and cognitive decline associated with calcium deposition on brain imaging.
