Relevance to Autism

Four de novo missense variants in the PPP2R5D gene were identified in seven unrelated patients with developmental delay/intellectual disability; five of these patients also presented with ASD (Shang et al., 2015). Two of the de novo PPP2R5D missense variants that were found in ASD cases in this report (p.Glu198Lys and p.Glu200Lys) have been previously identified in patients with intellectual disability (Deciphering Developmental Disorders Study, 2015; Loveday et al., 2015) and have been experimentally shown to result in reduced binding to the A and C subunits of protein phosphatase 2A (Houge et al., 2015). In addition to developmental delay/intellectual disability and, in some cases, ASD, individuals with PPP2R5D mutations frequently exhibit syndromic features including overgrowth, facial dysmorphism, and additional congenital anomalies. Oyama et al., 2022 studied 76 individuals withPPP2R5Dvariants, including 68 with pathogenic de novo variants and four siblings with a novel dominantly inherited pathogenic variant; functional analysis revealed impaired PP2A A/C-subunit binding, decreased short linear interaction motif-dependent substrate binding, or both, while the recurrent p.Glu198Lys missense variant showed the highest C-binding defect and a more severe clinical phenotype and the inherited p.Glu197Gly variant had a mild substrate binding defect. Furthermore, common clinical phenotypes of affected individuals in Oyama et al., 2022 were language, intellectual or learning disabilities (80.6%), hypotonia (75.0%), macrocephaly (66.7%), seizures (45.8%) and autism spectrum disorder (26.4%).

Molecular Function

This gene encodes a delta isoform of the regulatory subunit B56 subfamily and belongs to the phosphatase 2A regulatory subunit B family, which might modulate substrate selectivity and catalytic activity of protein phosphatase 2A, which is one of the four major Ser/Thr phosphatases and has been implicated in the negative control of cell growth and division.

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."

Four de novo missense variants in the PPP2R5D gene were identified in seven unrelated patients with developmental delay/intellectual disability; five of these patients also presented with ASD (Shang et al., 2015). Two of the de novo PPP2R5D missense variants that were found in ASD cases in this report (p.Glu198Lys and p.Glu200Lys) have been previously identified in patients with intellectual disability (Deciphering Developmental Disorders Study, 2015; Loveday et al., 2015) and have been experimentally shown to result in reduced binding to the A and C subunits of protein phosphatase 2A (Houge et al., 2015). In addition to developmental delay/intellectual disability and, in some cases, ASD, individuals with PPP2R5D mutations frequently exhibit syndromic features including overgrowth, facial dysmorphism, and additional congenital anomalies. De novo variants in the PPP2R5D gene (one frameshift, one benign missense) have been identified in SSC probands (Iossifov et al., 2015), although no additional phenotypic information for these probands is available.

Krishnan Probability Score

Score 0.49218662672243

Ranking 4686/25841 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 0.99752007894892

Ranking 1313/18225 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 0.46080103163505

Ranking 371/18665 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 0.47404963897159

Ranking 713/20870 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.
