Genetic insights into autism spectrum disorder with intellectual disability: a regional population-based study from Northwest China
To investigate the genetic etiology of autism spectrum disorder with Intellectual Disability in Northwest China.
Approach:
Study Design: Whole-exome sequencing was conducted on 125 children admitted to Yinchuan First People's Hospital.
Data Collection: Clinical information, imaging data, and results from developmental and ASD assessment scales were collected.
Variant Analysis: Variants and associated pathogenic mechanisms were analyzed, along with correlations between genotypes and clinical phenotypes.
Key Findings:
Forty-five positive cases were identified, yielding a positive detection rate of 36.0%.
The male-to-female ratio was 2:1.
Eight cases had copy number variations, and 37 cases had single-nucleotide variations/insertions and deletions.
Significant differences in gross motor developmental delay and abnormal electroencephalograms were found between positive and negative groups (q < 0.05).
A significant difference in autism spectrum disorder severity was observed between positive and negative groups (χ2 = 10.20, P < 0.01).
Interpretation:
Limitations:
The study was limited to a specific population in Northwest China.
The sample size may not be representative of the broader population.
