PERSEUS vs Evagene: pedigree visualisation vs clinical pedigree management

Short version. PERSEUS is an interactive and intuitive web-based pedigree visualisation tool, published in 2024 in Oxford Bioinformatics (btae060). It is academic, free, and focused on making pedigree visualisation comfortable and informative in a browser. Evagene is a clinical-grade pedigree management platform with gesture drawing, a 200+ disease catalogue coded to ICD-10 and OMIM, integrated BayesMendel cancer risk models (BRCAPRO, MMRpro, PancPRO), Mendelian inheritance analysis, AI clinical interpretation via bring-your-own-key (BYOK) LLMs, a REST API, webhooks, and an MCP server for AI agents. If your use case is research-stage pedigree visualisation — particularly large or complex pedigrees where PERSEUS's interactive design genuinely helps — PERSEUS is a solid, recent tool with academic credentials. If your use case is clinical pedigree management in a working service, Evagene is built for that end-to-end workflow.

This is an honest comparison. All PERSEUS claims are drawn from the 2024 Bioinformatics paper (btae060) and the product's public documentation as of April 2026.

How the two products position themselves

PERSEUS describes itself as an interactive and intuitive web-based pedigree visualisation tool. The emphasis is on the visualisation surface: a pedigree you can explore, zoom into, interact with, and understand, particularly for larger or more complex family structures than a static drawing handles gracefully. Its home is the scholarly record — the 2024 Bioinformatics publication is its primary credential, and its audience is the bioinformatics and genetics research community. Like many academic tools, it is free and open to the research community.

Evagene is positioned as clinical-grade pedigree management for precision medicine. Its canvas uses gesture drawing optimised for live consultation; its disease annotation is coded to ICD-10 and OMIM across a curated 200+ catalogue; its risk modelling runs BRCAPRO, MMRpro, and PancPRO from the BayesMendel suite directly on the pedigree; and its AI layer uses the service's own LLM keys (Anthropic Claude, OpenAI GPT, encrypted at rest with Fernet) to draft structured clinical reports. The platform surface — REST API, webhooks, MCP server (11 tools), embeddable pedigree viewer (iframe / SVG / JS), Analysis Templates — is a first-class part of the product, not an add-on.

In short: PERSEUS is a focused research visualisation tool. Evagene is a clinical platform in which the pedigree is the central data object and everything around it (drawing, coding, risk, AI, integration, reporting) is built in. The tools are respectable at what they each do; they just do different things.

Visualisation as a first-class concern

PERSEUS's strongest card is interactive visualisation. Pedigrees in a research context can be big — extended families with many generations, consanguineous loops, annotation overlays drawing on genomic or phenotypic data — and a static drawing struggles to handle that gracefully. PERSEUS was designed to handle such pedigrees with interactive controls that let the user explore and annotate without the cognitive overload of a crowded static image.

Evagene's canvas is also interactive and modern, and its embeddable viewer surfaces pedigrees across portals and dashboards. For the specific task of "I have a large, complex research pedigree and I want the best possible interactive exploration experience with minimal clinical overhead", PERSEUS's focused design may win. Evagene is broader in scope; PERSEUS is more narrowly optimised.

Clinical workflow and risk analytics

PERSEUS does not advertise integrated cancer risk modelling, a clinical disease catalogue, or clinical reporting pathways. The paper's focus is visualisation methodology; risk analysis and clinical workflow are not part of its declared scope.

Evagene integrates the clinical loop directly. BRCAPRO, MMRpro, and PancPRO run on the pedigree without re-entry. Mendelian inheritance calculators cover AD, AR, and XR patterns. Batch risk screening sweeps across the entire 200+ disease catalogue for a given proband, surfacing conditions whose family history crosses a risk or testing-eligibility threshold. Karyogram viewing shows chromosomal abnormalities alongside pedigree symbols. Consanguinity detection uses Wright's coefficient of inbreeding. Four clinical report types cover PNG, SVG, and PDF.

A research team can use PERSEUS for visualisation and move data into Evagene (or another clinical tool) for risk analysis. A clinical service has fewer reasons to adopt PERSEUS as the primary tool: the workflow benefits of integrated risk, coding, and reporting are exactly what PERSEUS deliberately does not provide.

AI, API, and integration surface

PERSEUS is a focused research tool, not an AI platform. It does not advertise AI interpretation, a public REST API, webhooks, or MCP integration.

Evagene includes AI clinical interpretation using bring-your-own-key Anthropic Claude and OpenAI GPT (keys Fernet-encrypted at rest), Analysis Templates for custom prompt-based reports, an MCP server exposing 11 pedigree tools to Claude Desktop / Claude Code / other MCP-compatible agents, a scoped REST API with rate-limited, SHA-256-hashed keys, HMAC-SHA256-signed webhooks, and an embeddable pedigree viewer. For clinics and services building AI-augmented workflows, this surface is the reason to choose Evagene.

Governance, security, and clinical fit

PERSEUS is research software. It will suit research settings well. It does not claim clinical certification, clinical-grade governance, or enterprise security controls — those were never its purpose.

Evagene applies baseline clinical controls: scoped API keys rate-limited and hashed with SHA-256 at rest; webhook payloads signed with HMAC-SHA256; LLM keys encrypted at rest with Fernet. Formal certification status (HIPAA, ISO 27001, Cyber Essentials Plus, NHS DSP Toolkit) should be confirmed directly with the vendor during procurement. Evagene is currently in Alpha; services making procurement decisions should factor in Alpha-stage expectations and the honest fact that a 2024 Oxford Bioinformatics paper is not a substitute for clinical certification (and nobody is claiming it is).

When to choose PERSEUS

• You are a researcher or bioinformatician who needs interactive, intuitive web-based pedigree visualisation.
• Your pedigrees are large, complex, or annotated with genomic or phenotypic data that benefits from interactive exploration.
• You value the credibility of a 2024 Oxford Bioinformatics publication and the open academic provenance that comes with it.
• Your workflow does not depend on integrated risk modelling, clinical reporting, or commercial integration surfaces.
• You are happy pairing PERSEUS with separate tools for other clinical or analytical tasks.

When to choose Evagene

• You are running a clinical service and the pedigree becomes part of the medical record.
• You need integrated cancer risk modelling (BRCAPRO, MMRpro, PancPRO) and Mendelian inheritance analysis without handoff to another tool.
• You want AI-assisted clinical interpretation using your own LLM keys (Anthropic, OpenAI).
• You are building AI agents, internal tooling, or patient portals that need programmatic access via REST API, webhooks, MCP, or embeds.
• You want broad import coverage (GEDCOM 5.5.1, JSON, 23andMe, XEG, pedigree image OCR) and 4 structured clinical report types.
• You draw pedigrees live during consultations and want gesture drawing optimised for that workflow.

Using PERSEUS and Evagene together

There is a sensible research-plus-clinic pattern. A research arm of a genetics service might use PERSEUS for interactive visualisation of research cohorts and publication figures, while the clinical arm runs Evagene for case management, risk analysis, AI-assisted reporting, and integration. Pedigrees can move between the tools via GEDCOM, image export, or via the Evagene REST API for structured data exchange. Running both is legitimate when the use cases do not overlap.
