Relevance to Autism

This gene has been associated with syndromic autism, where a subpopulation of individuals with a given syndrome develop autism. In particular, rare mutations in the HEPACAM gene have been found to cause either macrocephaly and mental retardation with or without autism or benign familial macrocephaly (Lpez-Hernndez et al., 2011).

Molecular Function

Involved in regulating cell motility and cell-matrix interactions. May inhibit cell growth through suppression of cell proliferation

SFARI Gene score
S

Syndromic

Rare mutations in the HEPACAM gene have been found to cause megalencephalic leukoencephalopathy with subcortical cysts (MLC) (Lopez-Hernandez et al., 2011); multiple individuals with MLC caused by heterozygous HEPACAM mutations (also known as remitting megalencephalic leukoencephalopathy with subcortical cysts-2B or MLC2B; OMIM 613926) were found to meet DSM-IV criteria for autism or PDD-NOS in this report. Phenotypic characterization of 38 patients with MLC2B in Hamilton et al., 2018 determined that autistic features were present in 25% of cases (9/36). A de novo potentially damaging missense variant in the HEPACAM gene (p.Arg92Trp) was identified in an ASD proband from the Simons Simplex Collection in Iossifov et al., 2014; this variant was also observed in multiple individuals with MLC2B in Lopez-Hernandez et al., 2011. An inherited missense variant in this gene that was predicted to be potentially damaging was observed in a Chinese ASD proband in Li et al., 2017.

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 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).

ExAC Score

Ranking 4843/18225 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

Ranking 1041/18665 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 -0.29044847828777

Ranking 17070/20870 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.
