Description
GeneTalk, is a web-based platform, tool, and database, for filtering, reduction and prioritization of human sequence variants from NGS data.Kamphans Tom Krwatiz, Peter GeneTalk: an expert exchange platform for assessing rare sequence variants in personal genomes Bioinformatics 23 July 2012 2012 July 28 19 2515–20156 10.1093/bioinformatics/bts462 22826540 3463119 http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3463119/ Users can edit annotation about sequence variants and build up a crowd sourced database with clinically relevant information for diagnostics of genetic disorders. GeneTalk also serves as an expert exchange platform for clinicians and scientists who are searching for information about specific sequence variants and connects them to share and exchange expertise on variants that are potentially disease-relevant.
Users can register at www.gene-talk.de and use basic feature for free.www.gene-talk.de
Application in diagnostics
GeneTalk is used by human geneticists, scientists, and clinicians for analysis and interpretation of sequence data from NGS for diagnostics of genetic disorders.
Registerd users can upload NGS data (in VCF format) of a patient onto the GeneTalk server. All entries of the file are listed in the integrated VCF viewer. A user has the possibility to edit a family tree for pedigree analysis. Using the intuitive filtering tools the user can reduce the number of clinically nonrelevant variants. After filtering and prioritization users can interpret the relevant variants by retrieving information (annotations) about variants from the GeneTalk database. Useres have the option to provide annotations to disease causing variants, by providing publications, comments, and further details about the variant.
Using the communication platform a user can contact experts about specific variants, genes, or genetic disorders, to exchange knowledge and expertise.
Analysis procedure
5 easy steps to analyze VCF files
Upload VCF file
Edit pedigree and phenotype information for segregation filtering
Filter your VCF file by editing the filtering options
View results and annotations
Write your own annotations
Filtering tools
GeneTalk offers a variety of filtering option to reduce the non-relevant sequence variants in VCF files.
Functional filter (filter out variants that have effects on protein level)
Linkage filter (filter out variants that are on specified chromosomes)
Gene panel filter (filter variants by genes or gene panels, subscribe to publically available gene panels or create own ones)
Frequency filter (show only variants with a genotype frequency lower than specified)
Inheritance filter (filter out variants by presumed mode of inheritance)
Annotation filter (show only variants that are listed in databases)
Communication platform & expert network
Users can share VCF files with colleagues and coworkers. The integrated mailig systems allows users to contact experts easily. Users can create annotations and comments and rate annotations regarding disease causing and trustworthiness. This information is helpful for interpretation of human sequence variants and diagnosis of genetic disorders. Registered users provide information about their field of knowledge in their profile and can be contacted by other users. Expertise of a user can consist of genetic disease, gene panels, or single genes.
Benefit for the user
