SCN1A (Sodium channel protein type 1 subunit alpha) is a gene. The public catalogues list it as a drug target, and an approved or late-stage drug is recorded against it.
Pore-forming subunit of Nav1.1, a voltage-gated sodium (Nav) channel that directly mediates the depolarising phase of action potentials in excitable membranes. Navs, also called VGSCs (voltage-gated sodium channels) or VDSCs (voltage-dependent sodium channels), operate by switching between closed and open conformations depending on the voltage difference across the membrane. In the open conformation they allow Na(+) ions to selectively pass through the pore, along their electrochemical gradient.
Open Targets scores its association with cancer at 0.54 (direct and indirect evidence; datatypes literature 0.39, animal model 0.37, genetic association 0.00, clinical 0.86).

No product in this corpus aims at SCN1A yet. Drugs bind the molecule precisely: to switch it off, flag the cell for the immune system, or deliver a payload.
Specificity not established: no corpus medicine is aimed at it and the catalogues give it only the role drug-target; HPA finds the RNA tissue enhanced, which says where the protein sits but not whether the tumour differs from normal tissue. HPA SCN1A: RNA tissue enhanced (brain 8 nTPM, retina 3 nTPM); no normal tissue stained high. Distribution: no corpus cancer carries a prevalence row, threshold or catalogue link for it; Open Targets associates it with 0 specific cancer types at or above 0.5. (No rule of scripts/fetch-target-specificity.ts fired.)

Pore-forming subunit of Nav1.1, a voltage-gated sodium (Nav) channel that directly mediates the depolarising phase of action potentials in excitable membranes. Navs, also called VGSCs (voltage-gated sodium channels) or VDSCs (voltage-dependent sodium channels), operate by switching between closed and open conformations depending on the voltage difference across the membrane. In the open conformation they allow Na(+) ions to selectively pass through the pore, along their electrochemical gradient. The influx of Na(+) ions provokes membrane depolarisation, initiating the propagation of electrical signals throughout cells and tissues. By regulating the excitability of neurons, ensures that they respond appropriately to synaptic inputs, maintaining the balance between excitation and inhibition in brain neural circuits. Nav1.1 plays a role in controlling the excitability and action potential propagation from somatosensory neurons, thereby contributing to the sensory perception of mechanically-induced pain. Location: Cell membrane (UniProt). Locus 2q24.3 (HGNC).
RNA: tissue enhanced (brain 8 nTPM, retina 3 nTPM), detected in some normal tissues.
No normal tissue stained high.
RNA cancer enriched: Glioblastoma Multiforme 3 pTPM.
No cancer sample stained medium or high.
