Rare Single Gene MutationRelevance to Autism
Two de novo variants (a missense variant and a synonymous variant predicted in PMID 26938441 to affect splicing regulation by altering an exonic splicing regulator) were observed in the CACNA1E gene in ASD probands (O'Roak et al., 2012; Neale et al., 2012). Evaluation of the statistical significance of observing multiple functional de novo variants in this gene, taking into account gene length and local sequence context to determine the expected number of variants, generated a p-value of 1.151E-02 (Takata et al., 2016).
Molecular Function
This gene encodes the alpha-1E subunit of R-type calcium channels, which belong to the 'high-voltage activated' group that may be involved in the modulation of firing patterns of neurons important for information processing.

Evaluation of the statistical significance of observing multiple functional de novo variants in this gene, taking into account gene length and local sequence context to determine the expected number of variants, generated a p-value of 1.151E-02 (Takata et al., 2016). Mice lacking the Ca(v)2.3 channel exhibited altered cerebellar function (Osanai et al., 2006). Lack of Ca(v)2.3 resulted in a marked decrease in the sensitivity of the animal to -butyrolactone-induced absence epilepsy in brain slices of Ca(v)2.3 knockout mice (Zaman et al., 2011). Ca(v)2.3 deficient mice exhibited reduced wake duration and increased slow-wave sleep (SWS) (Siwek et al., 2014). Helbig et al., 2018 described a developmental and epileptic encephalopathy with contractures, macrocephaly, and movement disorders associated with de novo missense variants in the CACNA1E gene; functional analysis of four of the missense variants observed in affected individuals (p.Phe698Ser, p.Ile701Val, p.Ala702Thr, and p.Ile603Leu) demonstrated gain-of-function effects.
