Systems and methods for genomic variant annotation
A system for annotating genomic variant files includes an application server, an annotation database, a genomic database, and an annotation processing computer system. The genomic database may be graph-oriented. The annotation processing computer system processes can process variant files in batch modes and includes annotation modules designed to improve the speed of the annotation process. The batch modes may include batch transmission, and/or batch annotation.
1. An electronic computer system for generating annotations of a subject,
the system comprising:
One or more processors;
A memory coupled to at least one of the one or more processors;
an application server that receives a variant file, the variant file comprising a variant list for a corresponding subject, the variant list comprising genomic variants found in a whole or partial genome sequence of the corresponding subject; an annotation processing computer system that receives the variant file from the application server, separates the genomic variants into variant groups according to chromosome, maps the genomic variants, separates the mapped variants into a plurality of annotation groups, and performs a parallel processing of the variant file, wherein the parallel processing includes at least annotating the annotation groups in parallel though a plurality of modules, to produce annotation data for the variant file, and an annotation database that receives the annotation data for the variant file and delivers the annotation data to the application server for generation of a genotype database.
2. The computer system of claim 1 , wherein the computer system generates at least 80 annotations for each variant at a rate of one hour per whole genome or faster.
3. The computer system of claim 1 , wherein the computer system generates at least 80 annotations for each variant at a rate of 30 minutes per whole genome or faster.
4. The computer system of claim 1 , wherein the plurality of modules can be selected from the group consisting of a mapping module, a non-synonymous-specific module, a transcript-specific module, a region-specific module, a variant-specific module, and combinations thereof.
5. The computer system of claim 1 , wherein the annotation processing computer system collects the annotation data back into variant groups after annotating the annotation groups in parallel though a plurality of modules.
6. The computer system of claim 1 , wherein the annotation processing computer system further processes the annotation data in a post-annotation module after annotating the annotation groups in parallel though a plurality of modules.
7. The computer system of claim 1 , wherein the annotation processing computer system collects the annotation data back into variant groups after annotating the annotation groups in parallel though a plurality of modules, and processes the variant groups of annotation data in a post-annotation module to produce annotation data for the variant file.
8. The computer system of claim 1 , wherein the annotation processing computer system is controlled by the application server.
9. The computer system of claim 1 , wherein the annotation processing computer system maps the genomic variants using a mapping module and the plurality of modules can be selected from the group consisting of a non-synonymous-specific module, a transcript-specific module, a region-specific module, a variant-specific module, and combinations thereof.
