DD/NDD, ADHD, ID, EP, EPS, ASDRelevance to Autism
Mutations appear to give rise to Dravet Syndrome as well as distinct epilepsy-related disorders and also migraine. Missense mutations were observed in cases from multiple unrelated families, one of which presented with seizures and Asperger Syndrome (asymptomatic carriers were also seen in families, but missense variants were not observed in any of 304 controls (Osaka H et al.). Autism seems to be common amongst individuals with Dravet Syndrome but the report does not give a frequency for the 20 individuals studied (Wolff M et al.). Rare missense variants were observed in 4/299 AGRE families but none of 96 controls, and one of these variants was found previously in a child with juvenile myoclonic epilepsy (Weiss LA et al.). De novo variants in SCN1A, including multiple missense variants that were predicted to be damaging and one likely gene-disruptive variant, have been identified in ASD probands (O'Roak et al., 2011; O'Roak et al., 2012; O'Roak et al., 2012; De Rubeis et al., 2014; Yuen et al., 2017). Assessment of a cohort of 35 individuals with Dravet syndrome using standardized tools demonstrated that 11 patients (39%) had ASD according to the DSM5 classification and ADIR and ADOS2 (Ouss et al., 2018). Additional de novo missense variants in the SCN1A gene were identified in novel ASD probands from the Autism Sequencing Consortium in Satterstrom et al., 2020; subsequent TADA analysis in this report identified SCN1A as a candidate gene with a false discovery rate < 0.1.
Molecular Function
This gene encodes the large alpha subunit of the vertebrate voltage-gated sodium channel essential for the generation and propagation of action potentials, mainly in nerve and muscle.

SFARI Gene score
High Confidence, Syndromic
Score Delta: Score remained at 1S
criteria met
See SFARI Gene'scoring criteriaWe considered a rigorous statistical comparison between cases and controls, yielding genome-wide statistical significance, with independent replication, to be the strongest possible evidence for a gene. These criteria were relaxed slightly for category 2.
The syndromic category includes mutations that are associated with a substantial degree of increased risk and consistently linked to additional characteristics not required for an ASD diagnosis. If there is independent evidence implicating a gene in idiopathic ASD, it will be listed as "#S" (e.g., 2S, 3S, etc.). If there is no such independent evidence, the gene will be listed simply as "S."

Description
Mutations appear to give rise to Dravet Syndrome as well as distinct epilepsy-related disorders and also migraine. Missense mutations were observed in cases from multiple unrelated families, one of which presented with seizures and Asperger Syndrome (asymptomatic carriers were also seen in families, but missense variants were not observed in any of 304 controls (Osaka H et al.). Autism seems to be common amongst individuals with Dravet Syndrome but the report does not give a frequency for the 20 individuals studied (Wolff M et al.). Rare missense variants were observed in 4/299 AGRE families but none of 96 controls, and one of these variants was found previously in a child with juvenile myoclonic epilepsy (Weiss LA et al.). De novo variants in SCN1A, including multiple missense variants that were predicted to be damaging and one likely gene-disruptive variant, have been identified in ASD probands (O'Roak et al., 2011; O'Roak et al., 2012; O'Roak et al., 2012; De Rubeis et al., 2014; Yuen et al., 2017). Assessment of a cohort of 35 individuals with Dravet syndrome using standardized tools demonstrated that 11 patients (39%) had ASD according to the DSM5 classification and ADIR and ADOS2 (Ouss et al., 2018).
