Selected Filters
No filters selected

The filters you have selected from various query interfaces will be stored here, in the 'Filter Cart'. The database will be queried using filters added to your 'Filter Cart', when multiple filters are defined, each will be executed using 'AND' logic, so with each filter that is applied the result set gets smaller.

From the 'Filter Cart' you can inspect each of the filters that have been defined, and you also have the option to remove filters. The 'Filter Cart' itself will display the number of filters applied along with the number of subjects that are identified by the combination of those filters. For example a GUID filter with two subjects, followed by a GUID filter for just one of those subjects would return only data for the subject that is in both GUID filters.

If you have a question about the filter cart, or underlying filters please contact the help desk at The NDA Help Desk

Autism genetics: homozygosity mapping and functional validation (Years 1-5)
Christopher A. Walsh 
Although high throughput sequencing (HTS) methods allow systematic analysis of genetic variation across the entire exome, or even the entire genome, the interpretation of this data faces analytical challenges that have by no means been solved. The use of consanguineous pedigrees, in which parents share ancestry, allows the identification of candidate genes that can then be analyzed more broadly in nonconsanguineous families. Consanguineous families 1] reduce the heterogeneity of ASD, 2] simplify HTS analysis and validation, and 3] provide genetic linkage evidence to support the validity of specific mutations in a single family. Preliminary data confirms that HTS in such pedigrees can efficiently identify, in an unbiased fashion, recessive genetic causes of ASD relevant to both consanguineous and nonconsanguineous cohorts of patients. This study will seek to enroll consanguineous families diagnosed with ASD, perform homozygosity mapping to locate regions of the genome likely to harbor the mutation that causes their ASD, and perform whole genome sequencing (WGS) on the affected individuals to identify candidate variants. Further, linkage and whole exome sequencing data that was generated on consanguineous families from previous studies will continue to be analyzed. This study will expand on the previous work by 1] Generating WGS data on normal controls to identify common alleles within Middle Eastern populations thus allowing swifter, more sensitive and ultimately cheaper analysis in this and many other Middle Eastern WGS studies; 2] Generating relatively high throughput methods of functionally validating strong candidate genes discovered through WGS using yeast models, transformed somatic cell lines, and other model systems; and 3] Using RNAi to generate mouse models of candidate genes discovered in this study, and an ongoing neuronal activity-dependent gene study, to examine the effects of removing the genes on dendrite and dendritic spine morphology and synaptic activity. Additionally, we performed deep sequencing of 78 known autism spectrum disorder (ASD) genes on 55 postmortem brains from individuals diagnosed with ASD. The data was analyzed for somatic mutations that contribute to ASD risk.

Associated Studies

Studies that have been defined using data from a Collection are important criteria to determine the value of data shared. The number of subjects column displays the counts from this Collection that are included in a Study, out of the total number of subjects in that study. The Data Use column represents whether or not the study is a primary analysis of the data or a secondary analysis. State indicates whether the study is private or shared with the research community.

Targeted DNA Sequencing from Autism Spectrum Disorder Brains Implicates Multiple Genetic Mechanisms Single nucleotide variants (SNVs), particularly loss-of-function mutations, are significant contributors to autism spectrum disorder (ASD) risk. Here we report the first systematic deep sequencing study of 55 postmortem ASD brains for SNVs in 78 known ASD candidate genes. Remarkably, even without parental samples, we find more ASD brains with mutations that are protein-altering (26/55 cases versus 12/50 controls, p = 0.015), deleterious (16/55 versus 5/50, p = 0.016), or loss-of-function (6/55 versus 0/50, p = 0.028) compared to controls, with recurrent deleterious mutations in ARID1B, SCN1A, SCN2A, and SETD2, suggesting these mutations contribute to ASD risk. In several cases, the identified mutations and medical records suggest syndromic ASD diagnoses. Two ASD and one Fragile X premutation case showed deleterious somatic mutations, providing evidence that somatic mutations occur in ASD cases, and supporting a model in which a combination of germline and/or somatic mutations may contribute to ASD risk on a case-by-case basis. 119 / 119 Primary Analysis Shared
Rare Inherited and De Novo CNVs Reveal Complex Contributions to ASD Risk in Multiplex families NOTE: NOT ALL DATA HAS BEEN UPLOADED FOR THIS STUDY. Rare mutations, including copy-number variants (CNVs), contribute significantly to autism spectrum disorder (ASD) risk. Although their importance has been established in families with only one affected child (simplex families), the contribution of both de novo and inherited CNVs to ASD in families with multiple affected individuals (multiplex families) is less well understood. We analyzed 1,532 families from the Autism Genetic Resource Exchange (AGRE) to assess the impact of de novo and rare CNVs on ASD risk in multiplex families. We observed a higher burden of large, rare CNVs, including inherited events, in individuals with ASD than in their unaffected siblings (odds ratio [OR] = 1.7), but the rate of de novo events was significantly lower than in simplex families. In previously characterized ASD risk loci, we identified 49 CNVs, comprising 24 inherited events, 19 de novo events, and 6 events of unknown inheritance, a significant enrichment in affected versus control individuals (OR = 3.3). In 21 of the 30 families (71%) in whom at least one affected sibling harbored an established ASD major risk CNV, including five families harboring inherited CNVs, the CNV was not shared by all affected siblings, indicating that other risk factors are contributing. We also identified a rare risk locus for ASD and language delay at chromosomal region 2q24 (implicating NR4A2) and another lower-penetrance locus involving inherited deletions and duplications of WWOX. The genetic architecture in multiplex families differs from that in simplex families and is complex, warranting more complete genetic characterization of larger multiplex ASD cohorts. 6 / 5288 Primary Analysis Shared
