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.

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.

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.

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).

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.
