Technical scheme is further described below by way of specific embodiment:
Embodiment 1:One cases of cancer Rapid matching system based on case transcript profile variation features
The present embodiment is made up of five big steps:
1) structure of how accurate medical knowledge base:Knowledge base is using correlation model as storage object, from U.S.'s food and medicine prison
Adjoint diagnostic medicine list, precision cancer biomedical information, the Sang Ge of My Cancer Genome offers of office (FDA) approval are provided
Three data sources of GDSC databases of research institute collect multigroup variation features associated by medicine response information.With diagnosis medicine
Thing and My Cancer Genome provide group variation features-medicine response information of population level, and GDSC databases are provided
Cell line level specific group of variation features-medicine response information.The data of different-format, pass through international standard data
The naming method that storehouse is provided is managed collectively.In this example, the single base mutation of separate sources is mapped to COSMIC numbers
According to correspondence title in storehouse, standard output is used as using the name in the database.Similarly, gene name is with NCBI entrez ID
As standard, disease name is used as standard using OMIM ID.
2) the multigroup extraction for learning variation features of case:Build the biological information that (RNA-Seq) data are sequenced based on transcript profile
Learn analysis process, from transcript profile extracting data and the closely related single base mutation of physiological change, chromosome structure be mutated with
And the gene of transcriptional level abnormal expression, as multigroup variation features of case, for learning variation features database with multigroup
In model matched.
In this example, the extraction flow of variation is divided into following components:RNA-Seq data predictions, it is single
Base mutation detects (SNP, small fragment insertion and deletion), chromosomal structural variation detection (Gene Fusion), gene
Expression and unconventionality expression genetic test, result visualization displaying.
First, RNA-Seq data predictions:
Initial data use quality control instrument checks the quality of data, is then used by the data of detection and removes joint software
Low quality base is cut off to the joint sequence in read and end to end.Read after cleaning is used for ensuing sequence alignment.
Here, this example compares software using quick short-movie section and human genome is compared as reference gene group.
2nd, the single base mutation of case is detected:
The RNA-seq variation detection best practices flows (http that this example is provided in this step according to GATK://
gatkforums.broadinstitute.org/gatk/discussion/3892/the-gatk-best-practices-
For-variant-calling-on-rnaseq-in-full-detail) operated.First to comparing obtained text in 1.
Part removes the read of redundancy, then read is carried out to cut out tail processing, and read is taken apart by extron section, base correction is performed, right
SNP and mononucleotide insertion and deletion are detected, finally using human genome variation database resource, are made
The single base variation detected is annotated and filtered with variation annotating software.
3rd, the chromosomal variation of case is detected:
The structure variation that transcript profile sequencing data can be detected predominantly Gene Fusion.Here to comparison result in 1.
Use the Gene Fusion event that can be seen on Gene Fusion software detection transcript profile.
4th, gene expression amount is detected:
The step for also using in 1. compare file as fragment assembly composite software input file, for transcribing
This splicing and the calculating of expression quantity.We are only considered without offer cancer beside organism and the transcription of disclosed cancer in this embodiment
Also the situation without cancer beside organism in group database.
5th, case group data result visual presentation:
The multigroup variation features of learning of the entirety of individual case are shown with loop graph.Loop graph is made up of four parts from inside to outside, most in
Face shows the generation position of Gene Fusion event, the generation position of single base mutation event is then shown, next to that base
Because of the expression in whole transcript profile, outermost layer is the chromosome position information with annotation.
All kinds of statistical charts produced during analysis, such as scatter diagram, histogram, pie chart are realized by statistic software R
Visualization output.
3) the multigroup realization for learning variation collaboration matching algorithm of case-model:Multigroup variation features database integration is more
Data source, the variation features information of the correlation model of multigroup angle.When case completes multigroup extraction for learning variation features, enter
, it is necessary to which there is provided the matching algorithm of case-model according to the type of model in database when entering case matching system.
In this example, knowledge base provides three class models:1. with diagnosis correlation model;2. cell line correlation model;
3. case correlation model.
The intervention result that the correlation model of population level is provided is typically for a certain or certain several variation of specific group
Influence of the feature in big population sample to medicine response.Therefore the strategy that example is used to the model is, when being compared such as
Fruit disease example and a population model have identical group of variation features, and the match is successful with the population model for reported cases,
Otherwise it fails to match.
The correlation model of cell line level and the correlation model of individual level are each provided with complete single base mutation, dyeing
Body structural mutation and gene expression spectrum information.Therefore this example employs a similarity score for combining this three aspects information
Method measures the similitude of case and model.Wherein using the correlation model and the correlation model of individual level of cell line level
It is finally to decide whether that the threshold parameter that the match is successful is different from the difference that case is matched.It is the reality of scoring method below
Existing step:
First, for single base mutation:This example measures the work(of single base mutation in case and model using DANN methods
Energy importance, respectively to occurring the progress of the DANN values in the site of notable single base function mutation in case and model on each gene
Summation, measures on the gene single base function mutation to physiological influence.It is similar that case and the gene function of this in model are mutated
Property score value can pass through formula 1- | Csnv-Msnv|/Max{Csnv,MsnvObtain, wherein CsnvDashed forward for the function of a certain gene in case
Become influence value, MsnvFor the function mutation influence value of model.The score value can be similar with the gene function of model as case is weighed
One index V1 of property.
2nd, for chromosomal structural variation:There is presently no method of the direct measure gene fusion to physiological effect degree.
Influence in view of usual structure variation to gene physiological function is very serious, this example with a customized index V2 (0 or
1) similitude of case and sample in Gene Fusion event is weighed.If in case and model, a certain gene there occurs
Gene Fusion or non-producer fusion, then V2 values are 1, and otherwise V2 values are 0.
3rd, for unconventionality expression gene:One index V3 of this example definition is abnormal to weigh gene expression amount, and formula is
V3=1- | Cexp-Mexp|/Max{Cexp,Mexp, wherein CexpAnd MexpRespectively express spectra case and mould after standardization
The expression quantity of a certain gene in type.
In this example, it is contemplated that abnormal gene expression has reacted the variation on transcriptional level, single base mutation or dyeing
Body structure variation has reacted the variation on genome, therefore needs both comprehensive effect when integrating these indexs.In example
Case is finally defined as V=Min { V3*V1, V3*V2 }, wherein V1, V2, V3 with model for the similarity score values of a certain gene
For specification three similarity indices mentioned hereinbefore.To a certain specific gene, if similarity score values are higher than 0.5, recognize
It is consistent with performance in model in case for the gene.When the gene that half is had more than in case is showed and their tables in a model
It is now consistent, then it is assumed that case and Model Matching success, otherwise it is assumed that it fails to match.
4) analysis report is produced according to the matching result of case:
Analysis report displaying is broadly divided into two parts:Individual case information and knowledge base searching result displaying.
Individual case information displaying is included in this example:
1. be sequenced sample essential information (comprising sample name, the sample presentation time, be sequenced the time, sequenator model, sample label,
Data saturation degree assesses parameter);
2. a group data integrally show figure, transcript profile sequencing data statistical information (includes the original read number of sample, after cleaning
Read number, compares the reading segment number information compared to the read number in reference gene group, specificity);
3. detect the expression and distribution histogram of the gene of expression, the chart of difference expression gene;
4. the quantity statistics and variation file format of single base variation and structure variation are understood on genome;
5. the expression document location of initial data QC reported positions, gene and transcript, the file position of difference expression gene
Put, the document location of single base variation information, the document location of Gene Fusion information.
The displaying of knowledge base searching result is included:
1. the essential information (types of models, initial data source, model name, disease name etc.) of the model matched;
2. support the evidence that case matches model (type of the index matched in model and case, index name, to refer to
Target metric etc.);
3. the clinical application reference information of the model matched (whether medicine name, model respond to medicine)
5) self-evolution of search system:
First, the renewal of accurate medical knowledge base:The case analyzed entering knowledge base is tracked, and treatment is abided by according to case
Therapeutic effect and long-term final result, set up case group variation features-intervention response correlation model, add knowledge base.To first entrance
Knowledge base does not search the case of Matching Model, it is considered to set up individuation disease model (PDX mouse models or PDO organoids
Model), the reaction according to external individuation disease model to different pharmaceutical, set up individuation disease model group variation features-
Medicine response correlation model, adds knowledge base.
