Abstract:
Autism spectrum disorder can be associated with a variety of genetic findings. We report a heterozygous de novo missense variant of SCN2A, the gene coding a voltage-gated sodium ion channel enriched in the axon initial segment and nodes of Ranvier of "immature" neocortical pyramidal neurons. With further understanding of the neurodevelopmental and functional effects of this missense variant on neuronal excitability and neocortical circuitry, there may be targeted pharmacotherapeutic interventions, potentially with "disease-modifying effects."

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%...
