The SCN2A gene encodes a protein (the α2 subunit of voltage-gated type II sodium channels) that helps neuronal firing throughout the brain .
If this gene is more active, it results in more firing between important brain regions involved in higher cognitive function. This results in better informational processing .
The brain regions involved are key regions supporting a broad range of cognitive processes including attention, working memory, conflict detection, and behavioral control .
Mutations in SCN2A is implicated in disorders such as autism and schizophrenia .
The SCN2A gene encodes the α2 subunit of voltage-gated type II sodium channels, which contribute to the generation and propagation of action potentials throughout the brain .
The α2 subunit encoded by SCN2A (Nav1.2) specifically mediates the conformational change of sodium channels based on voltage differences across cell membranes .
Furthermore, antiepileptic drugs that inhibit Nav1.2 activity (e.g., topiramate) are associated with a diminished intellectual function.
Mutations in SCN2A is implicated in disorders such as autism and schizophrenia, where impaired cognitive performance is often observed .
This gene increases the capacity for information processing between the dorsolateral prefrontal cortex and dorsal anterior cingulate cortex, which support higher cognitive functions .
This gene may contribute to the development of cortical and hippocampal circuits .
The dorsolateral prefrontal cortex and dorsal anterior cingulate cortex are key nodes supporting a broad range of cognitive processes including attention, working memory, conflict detection, and behavioral control .
The voltage-gated type II sodium channels process sensory inputs, including visual processing and/or disorders characterized by visual deficits .
This is thought to be mediated by the communication between the dorsolateral prefrontal cortex and the middle occipital gyrus .
SelfDecode has a few SNPs in the SCN2A gene:

The Basic Fix
If you have the SCN2A gene, that results in lower intelligence and you need to take a GSK3 beta inhibitor.
See my list of GSK3 beta inhibitors.
Sigma-1 receptor activators directly Inhibit NaV1.2/1.4 Channels .
Pregnenolone and DHEA are such activators, while progesterone is a blocker of this receptor . This means you should be careful about pregnenolone and DHEA supplements, but you should explore Progesterone. On the other hand, Pregnenolone readily converts to progesterone.
