Learn how to use GEBRA
Hello, We are 3billion.
We are a team of dedicated individuals(AI engineers, bioinformaticians, designers, medical geneticisits, and salesforces) to innovate rare genetic disease diagnostics and furthermore the treament.
Welcome to GEBRA, our diagnosis assist platform. GEBRA is cloud based software designed to analyze of genomic data and assist genetic professionals (clinicians, medical geneticists, variant scientists, bioinformaticians, etc) finding causal variant for rare disease patients' conditions. Figure below is a structure of GEBRA(figure 1).
It runs on AWS. The location of physical server may differ by user's location.Users can upload either FASTQ or VCF from their local computers to the server. Then it goes through our pipeline for variant calling and annotation. Once the data is analyzed, users can browse the analysis result and find out causal variants.For more detailed guide, please refer to this link.
Dashboard is the page where you will be right after log in.
A: Overall status of data you uploaded are shown according to the status of each sample(A).
B: Samples with low TAT are shown in Urgent Samples section(B).
C: In Activity section, you can see changes made on samples that are assigned to you(C).
'Projects' helps you creating and managing samples depends on the projects they belong.
You can set TAT, QC threshold and list of genes you are interested differently based on projects that you are working on.
While sample upload, you can choose a project that you want to include the sample to.
GEBRA leverages multiple callers for variant calling and filtering.
Variant types and callers for each type are listed below (Variant Type:Variant Callers).
· SNV/indel: GATK, Mutec2
· CNV: 3bCNV, MANTA, SMAfinder
· Inversion and breakend: MANTA
· Insertion: MELT, MANTA
· Repeat expansion: ExpansionHunter
· Region(Run) of Homozygosity: AutoMap
For more details, please refer to our white paper's '3billion’s Genomic Test Services' section (whitepaper 2024 link)
EVIDENCE, developed by 3billion, is a software for fast and accurate variant annotation.
Once variant calling is over, each variant files are by annotated by EVIDENCE, referring multiple databases and guidelines.
Classification of variant pathogenicity is based on the logics of ACMG/AMP guidelines.
For more details, please refer to our white paper's 'EVIDENCE' section (whitepaper 2024 link)
In 'See details' of each variant(only for SNV at the moment, other types of variants are under construction), users may change rules applied to the variant.
Logs of changed rules are recorded on the Knowledge Base of the institution and will be applied accordingly from the next analysis.
Users can check logs in the Knowledge Base on the Dashboard.
In Prioritized variant section, variants that went through multiple layers of filters are displayed.
Filters leverage bayesian score, applied rules/criteria, ClinVar, articles, etc.
Move the variants of All Variants to priority.
In All variants section, every variant except for variants with high population frequency(e.g. for SNV, BA1 applied variants are not shown in All variants section).
Priortized variants are also visible in this section.
Users can 'prioritize' (or move) variants from All variants to Proiritized section to generate a report, and if needed can leave a mark in 'See details'-'ACMG Classification'-'Edit'-'Prioritize this variant regardless of classification' to prioritize the variant automatically from next analysis.
