Background: Disco-interacting protein 2 C (DIP2C) has recently been reported as a new susceptibility gene for autism spectrum disorder (ASD) in a genome-wide association study.
Methods: We evaluated associations between single nucleotide polymorphisms (SNPs) of DIP2C and ASD susceptibility in a case-control study (715 ASD cases and 728 controls) from Chinese Han.
Results: We identified a significant association between SNPs (rs3740304, rs2288681, rs7088729, rs4242757, rs10795060, and rs10904083) and ASD susceptibility. Of note, rs3740304, rs2288681, and rs7088729 are positively associated with ASD under inheritance models; moreover, haplotypes with any two marker SNPs (rs3740304 [G], rs2288681 [C], rs7088729 [T], rs4242757 [C], rs10795060 [G], and rs10904083 [A]) are also significantly associated with ASD. Additionally, rs10795060 and rs10904083 are associated with "visual reaction" phenotypes of ASD.
Conclusions: DIP2C polymorphisms sort out the susceptibility and clinical phenotypes of autism spectrum disorder.

Importance: Current evidence of the association between prenatal exposure to glucocorticoids and long-term mental disorders is scarce and has limitations.
Objective: To investigate the association between prenatal exposure to systemic glucocorticoids and mental disorders in offspring at the age of 15 years, comparing exposed vs unexposed offspring born to mothers with the same underlying disease (risk of preterm delivery and autoimmune or inflammatory disorders).
Design, Setting, And Participants: This nationwide population-based cohort study used data from registries in Denmark with follow-up until December 31, 2018.

Background: Recent studies have shown that patients with attention-deficit/hyperactivity disorder (ADHD) are more likely to be diagnosed with mild cognitive impairment (MCI) and Alzheimer's Disease (AD). Increased genetic risk for ADHD, measured with ADHD polygenic risk scores (ADHD-PRS), was associated with a more severe AD presentation, including worse cognitive function and higher tau pathology. Neuropsychiatric symptoms (NPSs) are common in AD and are hypothesized to occur with disease progression.

Background: Autism spectrum disorder (ASD) appears to be a common neurological developmental deficit disorder in pediatric patients, resulting in a tremendous burden on society.
Purpose: The article aimed to explore early diagnostic markers for ASD.
Methods: Levels of long non-coding RNA (lncRNA) H19 and microRNA-484 (miR-484) were detected using fluorescence quantitative polymerase chain reaction (PCR).

The cerebellum plays a crucial role in functions, including sensory-motor coordination, cognition, and emotional processing. Compared to the neocortex, the human cerebellum exhibits a protracted developmental trajectory. This delayed developmental timeline may lead to increased sensitivity of the cerebellum to external influences, potentially extending the vulnerability period for neurological disorders.

The aim of this study was to adapt the Children Participation Questionnaire (CPQ) into Turkish culture and evaluate its psychometric properties in typically developing children aged 4-6 years. This study involved 235 typically developing children and 61 children with autism spectrum disorder (ASD). Parents completed the Turkish CPQ (CPQ-T) and demographic form.
