Relevance to Autism

Several studies have found rare single gene mutations, including deletions and missense mutations, in the PTCHD1 gene that have associations with autism. For example, Marshall et al. (2008) found a 160kb deletion that results in a null mutation for the PTCHD1 gene.

Molecular Function

PTCHD1 is suggested to be a transmembrane protein containing a patched-related domain with twelve transmembrane helices, highly related to the Hedgehog (Hh) receptors PATCHED1 (PTCH1) and PTCH2 as well as to Niemann-Pick Type C1 protein (NPC1).

Description

There is strong evidence for the role of PTCHD1, an X-linked gene, in autism, based on the finding of deletions and mutations disrupting the gene in affected individuals but not in controls (see Noor et al. ,2010, Marshall et al., 2008, Pinto et al., 2010). These reports include a deletion transmitted from an unaffected mother with skewed X inactivation to 2 affected twin sons and an unaffected daughter. There is also a deletion in 1/246 males in an intellectual disability cohort. Sequence analysis in 723 male ASD, 177 female ASD, and 225 male cases of intellectual disability revealed 7 missense mutations in 8 cases. These same changes were not seen in 700 controls (p=0.042 enrichment case v ctrl). Deletions upstream of PTCHD1 were also reported in 8/996 ASD probands, but none in 4829 male controls.

Krishnan Probability Score

Score 0.49643212954265

Ranking 2601/25841 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 0.94705307870957

Ranking 2730/18225 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 0.94006252689679

Ranking 14432/18665 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).
Larsen Cumulative Evidence Score

Score 45

Ranking 42/461 scored genes


[Show Scoring Methodology]
Larsen and colleagues generated gene scores based on the sum of evidence for all available ASD-associated variants in a gene, with assessments based on mode of inheritance, effect size, and variant frequency in the general population. The approach was first presented in Mol Autism 7:44 (2016), and scores for 461 genes can be found in column I in supplementary table 4 from that paper.
Zhang D Score

Score 0.18202098061414

Ranking 4562/20870 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.
