Klinikum Nürnberg, Paracelsus Medizinische Privatuniversität, Breslauerstr. 201, 90471, Nürnberg, Deutschland.

Atypical Parkinson syndromes represent a neuropathologically heterogeneous group and include the clinical entities dementia with Lewy bodies (DLB), multiple system atrophy (MSA), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD). The DLB and MSA are characterized by deposition of the protein alpha-synuclein (synucleinopathy), PSP and CBD are characterized by deposition of tau protein, often in the form of neurofibrillary tangles in nerve and glial cells (tauopathy). Misfolding and aggregation of the aforementioned proteins causes degeneration of the affected cell populations but the disease also spreads to anatomically neighboring brain regions, thus contributing to disease progression.

Department of Neurology, Royal Victoria Infirmary, Newcastle upon Tyne NE1 4LP, United Kingdom.

variants are known to cause Cornelia de Lange Syndrome (CdLS) which encompasses a clinical spectrum of intellectual disability, dysmorphic features (long or thick eyebrows, a hypomorphic philtrum and small nose) and, in some cases, epilepsy. More recently, truncating variants have been described as the cause of a neurodevelopmental disorder with early-childhood onset drug-resistant epilepsy with seizures that occur in clusters, similar to that seen in -related epilepsy, but without the classical features of CdLS. Here, we report the case of a 28-year-old woman with a heterozygous truncating variant in who unusually presented with seizures at the late age of 12 years and had normal development into adulthood.
