Summary: Emotion recognition skills and understanding of others' mental states are crucial for social functioning. Autistic children show poorer performance in emotion recognition and theory of mind compared to typically developing children, while unaffected siblings do not differ significantly from typically developing children in these abilities.

Summary: Relatives of individuals with autism spectrum disorder may display milder social traits known as the broader autism phenotype, indicating potential genetic risk for ASD. This study found an inherited pattern of graded difficulties in social cognition in families with ASD and the BAP, with atypical faux pas detection being a potential endophenotype for ASD. Objective measures of social skills can help identify genetic risk for ASD and facilitate research on the genetic causes of ASD in this population.

Summary: Autism spectrum disorder (ASD) is characterized by different social interaction styles, including difficulties in facial emotion recognition and expression. This review highlights the importance of studying both subtle emotion recognition and emotion expression in individuals with ASD to bridge the gap between intervention and research. Proposed teaching methods for FER include using posed vs. genuine emotions and static vs. dynamic stimuli to improve generalizability and learning progressions.

Summary: Limited information is available on the development of self-regulation processes during the preschool period in children with Autism Spectrum Disorder (ASD). Parental characteristics, such as the broader autism phenotype (BAP), play a role in children's self-regulation, with mothers' BAP traits impacting self-regulation outcomes differently across groups. Emotion regulation was found to be a protective factor against internalizing behavioral concerns in children with ASD. Parental factors should be taken into consideration in emotion regulation interventions for young children with ASD.

Summary: Past research suggests that individuals with autism spectrum disorder (ASD) have difficulties in decoding facial expressions. However, this study found that children with ASD who owned a service dog exhibited more focused visual scanning strategies during facial expression processing. They directed less attention to irrelevant areas and displayed a more differentiated scanning of relevant facial features.

Summary: The broad autism phenotype refers to sub-clinical levels of autistic-like behavior and cognition in biological relatives of autistic people. A recent study found that increased facial masculinity may also be a feature of the broad autism phenotype. This study further investigated the presence of increased facial masculinity among non-autistic parents of autistic children and found that they had significantly higher masculinity scores and larger facial distances compared to a comparison group.

Summary: The study found that facial emotion training can significantly improve emotion recognition in individuals with ASD, but further research is needed to investigate the generalization and maintenance effects of the training, and there is currently no experimentally verified improvement in social skills.

Summary: Using a new computerized task, this study examined the relationship between social anxiety symptoms and individual differences in facial emotion recognition (FER) among autistic male adolescents and young adults without intellectual disability. The results revealed that social anxiety and IQ were predictors of poorer FER, regardless of specific emotion types. Furthermore, social anxiety affected surprise and disgust FER during a truncated viewing condition but not in full viewing condition. Overall, these findings suggest that social anxiety may play a larger role in FER among individuals with autism than previously believed. Future research should consider the role of social anxiety in autism as a significant factor in FER assessment and intervention.

Summary: The study found differences in emotion recognition between autistic and non-autistic individuals, with autistic participants showing lower accuracy for angry facial motion. Autistic traits were predictive of accuracy for angry facial motion, while alexithymic traits were predictive of the magnitude of emotion ratings.

Summary: Genetic variants in the SLC6A1 gene can cause a broad spectrum of phenotypic diseases by altering the protein function. Through the aggregation of genetic and clinical data, as well as functional data, the study found potential associations between variant positions on the GAT1 3D structure, variant pathogenicity, altered molecular function, and phenotype severity.

Summary: The study found that individuals with autism spectrum disorder (ASD) exhibit preserved neural responses to violations of local emotion regularity at an early processing stage, but a lack of neural responses to violations of global emotion regularity at a later stage. These findings reveal that the processing of emotional regularity in the autistic brain is modulated by the timescale of sequential stimuli.

Summary: Exome sequencing has been demonstrated to have clinical utility in the management of patients with DEEs, providing molecular diagnosis, guiding treatment, and informing accurate prognosis and reproductive counseling. Ongoing analysis of genomic data is necessary to identify the cause in patients with unknown etiology. The routine implementation of genomic testing in the care of children with DEEs should be considered in clinical practice.

Summary: Long-term use of fenfluramine showed sustained reduction in drop seizure frequency in LGS patients, with significant reduction in the frequency of GTCS and tonic seizures. The drug was generally well tolerated with minimal adverse effects and no significant cardiac side effects observed. Fenfluramine may serve as an important long-term treatment option for patients with LGS.

Summary: This study analyzed the epileptology and imaging features of WWOX-DEE, and investigated genotype-phenotype correlations, particularly with regard to survival. The results showed that biallelic WWOX pathogenic variants cause an early infantile developmental and epileptic encephalopathy syndrome, with focal seizures and epileptic spasms being the most common seizure types. Patients with two null WWOX pathogenic variants have higher mortality risk.

Summary: Familial adult myoclonic epilepsy (FAME) is a under-recognized disorder characterized by cortical myoclonus, generalized tonic-clonic seizures, and additional clinical symptoms, which vary depending on the FAME subtype. FAME is caused by pentanucleotide repeat expansions of intronic TTTCA/TTTTA in different genes.

Summary: BRAT1 biallelic variants are associated with two syndromes, one is a severe phenotype with rigidity and multifocal seizure, and the other is a milder phenotype with cerebellar atrophy. Genotype-phenotype correlations show that different variants are associated with different phenotypes, with nonsense and frameshift variants causing the severe phenotype, missense variants more likely associated with the milder phenotype, and splice variants showing variable phenotypes.

Summary: Pathogenic variants in HCN1 gene are associated with epilepsy syndromes. The Hcn1M294L mouse model shows seizure and behavioral phenotypes similar to patients. Mutated HCN1 channels in photoreceptors lead to reduced sensitivity to light and impaired processing of temporal information. This study highlights the importance of HCN1 channels in retinal function and the impact of HCN1 pathogenic variants on visual function.

Summary: This review examines the significance of seizures in young athletes and the complex inter-relationship between seizures, epilepsy, and sudden cardiac death. Recent findings suggest that epilepsy may be associated with sudden unexplained cardiac death, with some patients experiencing a cardiocerebral channelopathy. It is important to consider the possibility of misdiagnosis of cardiac syncope in athletes with a history of seizures, requiring careful cardiac evaluation and risk stratification. Further investigation is needed to fully understand the association between seizures and young sudden cardiac death.

Summary: Aicardi Syndrome is a rare neurodevelopmental disorder characterized by agenesis of the corpus callosum, chorioretinal lacunae, and infantile epileptic spasms. Although extensive genetic and genomic investigations have been conducted, no X-linked cause has been found. This study identified unique de novo variants in different genes in 5 out of 10 females with Aicardi Syndrome, suggesting genetic heterogeneity and involvement of molecular pathways related to cortical development.
