Relevance to Autism

Variants affecting the CACNA1A gene were identified in affected individuals from four unrelated families presenting with a spectrum of cognitive impairment including intellectual disability, executive dysfunction, ADHD and/or autism, as well as childhood-onset epileptic encephalopathy with refractory absence epilepsy, febrile seizures, downbeat nystagmus and episodic ataxia (Damaj et al., 2015). Damaging missense and likely loss-of-functions in CACNA1A, many of which were de novo in origin, have subsequently been identified in individuals presenting with similar phenotypes (Epi4K Consortium 2016; Lelieveld et al., 2016; Eldomery et al., 2017; Vissers et al., 2017; Hamdan et al., 2017). A de novo synonymous variant in the CACNA1A gene was identified in an ASD proband from the Simons Simplex Collection in Iossifov et al., 2014; this variant was located near a splice-site and was predicted to affect splicing by altering the exonic splicing regulator (ESR) in Takata et al., 2016. SNPs in the CACNA1A gene associated with autism in a Chinese Han population in Li et al., 2015, although this association did not survive after Bonferroni correction. Mice carrying loss-of-function mutations in Cacna1a in a subset of cortical interneurons display severe generalized epilepsy (Rossignol et al., 2013). Lipman et al., 2022 reported 47 individuals with 33 unique pathogenic or likely pathogenic variants in CACNA1A; developmental delay/intellectual disability was observed in 96% of affected individuals, and autism spectrum disorder was reported in 23% of affected individuals.

Molecular Function

This gene encodes the pore-forming alpha-1A subunit, which is predominantly expressed in neuronal tissue, for voltage-dependent calcium channels. Mutations in this gene are associated with several neurological disorders: episodic ataxia, type 2 (OMIM 108500); migraine, familial hemiplegic, 1 (OMIM 141500); and spinocerebellar atxia 6 (OMIM 183086).

SFARI Gene score

High Confidence, Syndromic

Score Delta: Score remained at 1S

criteria met

See SFARI Gene'scoring criteria

High Confidence

See all Category 1 Genes

We 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.

Syndromic

See all Category S Genes

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."

Krishnan Probability Score

Score 0.61038153156471

Ranking 231/25841 scored genes

[Show Scoring Methodology]

Krishnan and colleagues generated probability scores genome-wide by using a machine learning approach on a human brain-specific gene network. The method was first presented in Nat Neurosci 19, 1454-1462 (2016), and scores for more than 25,000 RefSeq genes can be accessed in column G of supplementary table 3 (see: http://www.nature.com/neuro/journal/v19/n11/extref/nn.4353-S5.xlsx). A searchable browser, with the ability to view networks of associated ASD risk genes, can be found at asd.princeton.edu.

ExAC Score

Score 0.99999999977629

Ranking 80/18225 scored genes

[Show Scoring Methodology]

The Exome Aggregation Consortium (ExAC) is a summary database of 60,706 exomes that has been widely used to estimate 'constraint' on mutation for individual genes. It was introduced by Lek et al. Nature 536, 285-291 (2016), and the ExAC browser can be found at exac.broadinstitute.org. The pLI score was developed as measure of intolerance to loss-of- function mutation. A pLI > 0.9 is generally viewed as highly constrained, and thus any loss-of- function mutations in autism in such a gene would be more likely to confer risk. For a full list of pLI scores see: ftp://ftp.broadinstitute.org/pub/ExAC_release/release0.3.1/functional_gene_constraint/fordist_cle aned_exac_nonTCGA_z_pli_rec_null_data.txt

Sanders TADA Score

Score 0.94806684873626

Ranking 17532/18665 scored genes

[Show Scoring Methodology]

The TADA score ('Transmission and De novo Association') was introduced by He et al. PLoS Genet 9(8):e1003671 (2013), and is a statistic that integrates evidence from both de novo and transmitted mutations. It forms the basis for the claim of 65 individual genes being strongly associated with autism risk at a false discovery rate of 0.1 (Sanders et al. Neuron 87, 1215-1233 (2015)). The calculated TADA score for 18,665 RefSeq genes can be found in column P of Supplementary Table 6 in the Sanders et al. paper (the column headed 'tadaFdrAscSscExomeSscAgpSmallDel'), which represents a combined analysis of exome data and small de novo deletions (see www.cell.com/cms/attachment/2038545319/2052606711/mmc7.xlsx).

Zhang D Score

Score 0.41840424797678

Ranking 1256/20870 scored genes

[Show Scoring Methodology]

The DAMAGES score (disease-associated mutation analysis using gene expression signatures), or D score, was developed to combine evidence from de novo loss-of- function mutation with evidence from cell-type- specific gene expression in the mouse brain (specifically translational profiles of 24 specific mouse CNS cell types isolated from 6 different brain regions). Genes with positive D scores are more likely to be associated with autism risk, with higher-confidence genes having higher D scores. This statistic was first presented by Zhang & Shen (Hum Mutat 38, 204- 215 (2017), and D scores for more than 20,000 RefSeq genes can be found in column M in supplementary table 2 from that paper.
