Gene Summary:

DBD Genes Classification
SCN8A is an Emerging candidate gene classified as Tier 2. Tier 2 genes have two de novo pathogenic loss-of-function variants.
Gene Function
Mediates the voltage-dependent sodium ion permeability of excitable membranes (PubMed:29726066). Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a sodium-selective channel through which Na(+) ions may pass in accordance with their electrochemical gradient. {ECO:0000269|PubMed:19136557, ECO:0000269|PubMed:29726066, ECO:0000269|PubMed:33245860, ECO:0000269|PubMed:36696443, ECO:0000269|PubMed:36823201}.

NCBI: Gene

Integrates information from a wide range of species. A record may include nomenclature, Reference Sequences (RefSeqs), maps, pathways, variations, phenotypes, and links to genome-, phenotype-, and locus-specific resources worldwide.

Gene Reviews

An international point-of-care resource for busy clinicians, provides clinically relevant and medically actionable information for inherited conditions in a standardized journal-style format, covering diagnosis, management, and genetic counseling for patients and their families.

DECIPHER

DECIPHER (DatabasE of genomiC varIation and Phenotype in Humans using Ensembl Resources) is an interactive web-based database which incorporates a suite of tools designed to aid the interpretation of genomic variants. DECIPHER enhances clinical diagnosis by retrieving information from a variety of bioinformatics resources relevant to the variant found in the patient.

SFARI

SFARI Gene is an evolving online database designed to permit quick entrée into the genetics of autism, and to help researchers track the ever-expanding genetic risk factors that emerge in the literature.

ClinGen

ClinGen is a National Institutes of Health (NIH)-funded resource dedicated to building an authoritative central resource that defines the clinical relevance of genes and variants for use in precision medicine and research.

GenCC

The GenCC DB provides information pertaining to the validity of gene-disease relationships, with a current focus on Mendelian diseases.

gnomAD

The Genome Aggregation Database (gnomAD) is a resource developed by an international coalition of investigators, with the goal of aggregating and harmonizing both exome and genome sequencing data from a wide variety of large-scale sequencing projects, and making summary data available for the wider scientific community.
