Recent advances have substantially increased the number of genes associated with complex genetic disorders of the CNS such as autism and schizophrenia. It is now clear that there are hundreds of distinct loci contributing to these disorders, underscoring a remarkable genetic heterogeneity. However, the commonality of symptoms across patients indicates there must be a functional convergence downstream of these loci upon the circuits mediating the affected behaviors. One possible mechanism for this convergence would be the selective expression of at least a subset of these genes in the cell types that comprise the circuit. Here, we have provided a simple web server implementing our approach of Cell-type Specific Expression Analysis (CSEA), for identifying candidate cell populations likely to be disrupted across a set of patients with diverse genetic lesions. This leverages a mouse transcriptomic profiling dataset to identify sets of transcripts specifically expressed in particular mouse cells. Though data from specific cell types in the brain is not available in humans, we have also analyzed human data from the Brainspan collection to provide a parallel analysis of transcripts enriched in particular human brain regions, and/or developmental windows.
The results will be shown in a page in about one minute...
This server can accept as an input lists of gene symbols (as assigned by HUGO), and returns an enrichment analysis of their expression across the currently available cell types and regions (Table 1). Candidate genes lists that overlap with lists of transcripts enriched in a particular cell type or region are identified by Fisher's exact test with Benjamini-Hochberg correction.
