Beyond standard variant detection and annotation, BMKGENE offers advanced bioinformatics analyses for hereditary disease and tumor research. Analysis modules can be selected and customized according to the study design, sample type, and research objectives.
Customized analytical workflows, software tools, parameter settings, and project-specific analyses are available according to individual research requirements.
The following figures illustrate representative outputs from BMKGENE’s hWGS bioinformatics workflows. Available analyses and deliverables may vary depending on the study design, sample type, sequencing strategy, and selected analysis modules.
The Circos plot provides an integrated chromosome-level overview of genomic alterations, enabling rapid assessment of genome-wide variation patterns.

Copy-Number Alteration and Loss of Heterozygosity Profile
Normalized copy-number and B-allele frequency (BAF) profiles across chromosomes reveal copy-number gains and losses and help identify regions of loss of heterozygosity. |
Somatic Mutation Landscape
The oncoplot summarizes recurrently altered genes, mutation classes, and their distribution across tumor samples, supporting the identification of candidate driver genes. |
Representative candidate variants in cancer-related genes are summarized with their genomic positions, variant classes, amino acid changes, associated cancer types, and reported roles in cancer.
|
NMF-Derived Mutational Signatures
Non-negative matrix factorization (NMF) decomposes somatic substitutions into characteristic trinucleotide profiles, helping identify the mutational processes that may have contributed to tumor development. |
Mutational Signature Contributions Across Samples
The stacked bar chart shows the contribution of each extracted mutational signature to individual tumor samples, highlighting differences in the underlying mutational processes across samples. |
|
Tumor Purity and Ploidy Estimation
The likelihood contour plot displays the estimated tumor cellularity and ploidy, together with confidence regions and alternative solutions. |
Tumor Subpopulation and Clonal Architecture
Adjusted variant allele frequencies and copy-number states are integrated to visualize inferred tumor subpopulations, supporting the assessment of intratumor heterogeneity and clonal architecture. |
