Abstract:
Autism spectrum disorder (ASD) is a clinically heterogeneous developmental disorder with a strong genetic component. Rare genetic disorders and various chromosomal abnormalities are thought to account for approximately 10% of people with ASD. The etiology of the remaining cases remains unknown. Recent advances in array-based technology have increased the resolution in detecting submicroscopic deletions and duplications, referred to as copy-number variations. ASD-associated copy-number variations, which are considered to be present in individuals with ASD but not in unaffected individuals, have been extensively investigated. These data will provide us with an opportunity not only to search for genes causing or contributing to ASDs but also to understand the genetics of ASD.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
