Abstract

Objective: The postsynaptic density protein of excitatory neurons PSD-95 is encoded by discs large MAGUK scaffold protein 4 (DLG4), de novo pathogenic variants of which lead to DLG4-related synaptopathy. The major clinical features are developmental delay, intellectual disability (ID), hypotonia, sleep disturbances, movement disorders, and epilepsy. Even though epilepsy is present in 50% of the individuals, it has not been investigated in detail. We describe here the phenotypic spectrum of epilepsy and associated comorbidities in patients with DLG4-related synaptopathy. Methods: We included 35 individuals with a DLG4 variant and epilepsy as part of a multicenter study. The DLG4 variants were detected by the referring laboratories. The degree of ID, hypotonia, developmental delay, and motor disturbances were evaluated by the referring clinician. Data on awake and sleep electroencephalography (EEG) and/or video-polygraphy and brain magnetic resonance imaging were collected. Antiseizure medication response was retrospectively assessed by the referring clinician. Results: A large variety of seizure types was reported, although focal seizures were the most common. Encephalopathy related to status epilepticus during slow-wave sleep (ESES)/developmental epileptic encephalopathy with spike–wave activation during sleep (DEE-SWAS) was diagnosed in >25% of the individuals. All but one individual presented with neurodevelopmental delay. Regression in verbal and/or motor domains was observed in all individuals who suffered from ESES/DEE-SWAS, as well as some who did not. We could not identify a clear genotype–phenotype relationship even between individuals with the same DLG4 variants. Significance: Our study shows that a subgroup of individuals with DLG4-related synaptopathy have DEE, and approximately one fourth of them have ESES/DEE-SWAS. Our study confirms DEE as part of the DLG4-related phenotypic spectrum. Occurrence of ESES/DEE-SWAS in DLG4-related synaptopathy requi

Abstract

Bainbridge-Ropers Syndrome (BRPS) is a genetic condition resulting from truncating variants in the ASXL3 gene. The clinical features include neurodevelopmental and language impairments, behavioral issues, hypotonia, feeding difficulties, and distinctive facial features. In this retrospective study, we analyzed 22 Spanish individuals with BRPS, aiming to perform a detailed clinical and molecular description and establish a genotype-phenotype correlation. We identified 19 ASXL3 variants, nine of which are novel. We documented recurrence in nontwin siblings due to parental mosaicism. The predominant prenatal finding was intrauterine growth restriction (35%) followed, after birth, by feeding difficulties (90.5%), hypotonia (85.7%), and gastroesophageal reflux disease (82.4%). Later in life, intellectual disability, language impairment, autism spectrum disorder (75%), and joint laxity (73.7%) were noted. Individuals with variants in the 3' mutational cluster region (MCR) of exon 12 exhibited more perinatal feeding problems, and those with variants in the 5' MCR of exon 11 displayed lower percentiles in height and occipitofrontal circumference, as well as higher frequency of arched eyebrows. This study is the first characterization of a Spanish BRPS cohort, with more than 50 clinical features analyzed, representing the most detailed phenotypic analysis to date., (© 2025 John Wiley & Sons A/S.
