Pedigree chart template: printable, PDF, spreadsheet, and digital alternatives
Templates — printable PDFs, spreadsheet forms, slide templates, and the NHS family-history worksheet — remain part of the clinical toolkit, but they have specific strengths and limitations. This page covers when a template is still the right choice and when modern pedigree software is a better fit.
Written for clinical educators, primary-care clinicians running family-history intake, and genetic counsellors balancing low-friction paper tools with digital structured-data needs.
Short version. Pedigree chart templates — printable PDFs, blank PowerPoint layouts, spreadsheet forms, and dedicated paper family-history cards — are low-friction tools with specific uses: teaching, pre-visit intake from patients, bedside documentation when software is not available, and quick sketch work. They do not enforce notation consistency, they do not run analyses, they do not store structured data for downstream use, and they are difficult to share across institutions without transcription. Modern pedigree software replaces the analytical role of templates but not always the intake role, and many services combine both: paper for intake, digital for structured analysis and long-term record.
Template formats
The main template formats encountered in clinical practice are:
- Printable PDF templates: pre-drawn blank pedigree grids, often with a symbol legend along the margin. Designed to be printed and filled in by hand.
- PowerPoint or Keynote slide templates: editable pedigree symbols and connectors that can be assembled on a slide. Often used in teaching and for report graphics.
- Spreadsheet forms: row-per-individual capture with columns for sex, birth year, conditions, relationships. Useful for structured intake but not visually a pedigree.
- Dedicated family-history worksheets: paper cards (the NHS HEE family-history template is the UK reference example) with prompts for each generation and a space for the clinician or patient to sketch.
- Word document pedigree forms: typeset skeletons that can be completed electronically or printed.
Each format has a different sweet spot. A printable PDF works for ad-hoc clinical documentation. A slide template works for teaching. A spreadsheet is the input format of choice for some research workflows. A family-history worksheet is optimised for patient self-completion before a consultation.
When a template is appropriate
- Teaching: a blank template is the natural starting point when students are learning pedigree notation by hand. Pencil-and-paper teaching reinforces the symbol set and discourages over-reliance on software defaults.
- Patient intake before a consultation: a family-history card sent to the patient in advance allows them to gather information at home without clinical time pressure.
- Bedside documentation: when software is not immediately available (a home visit, a bedside encounter, a field research setting), a paper template preserves the pedigree.
- Quick reference: a printed symbol-legend page by the clinician's desk supports consistency without needing the software for every reference.
- Archival of legacy records: where services have decades of paper pedigrees, templates describe the conventions under which those records were made.
Limitations of templates
The main limitations are:
- Notation is not enforced. Hand-drawn pedigrees vary in consistency even when the intent is to follow NSGC conventions. Multiple clinicians in the same service can produce visibly different diagrams for the same family.
- No analytical function. A paper template does not run inheritance pattern analysis, Bayesian carrier probability, BRCAPRO/MMRpro/PancPRO cancer risk models, or consanguinity detection with Wright's coefficient.
- No structured data. Information captured on paper is free text. It cannot be searched, queried, or aggregated without transcription into a digital system.
- Difficult cross-institution sharing. A paper pedigree must be photographed, scanned, or transcribed before it can be sent to another service.
- Hard to update. As family information changes, a paper pedigree must be redrawn rather than edited.
- Legibility risks. Handwriting varies; rushed entries become hard to read; small annotations get lost.
These limitations explain why most genetics services have moved analytical work into digital pedigree software while keeping templates in the intake and teaching parts of the workflow.
The NHS family-history worksheet as a reference
Within UK primary care and genetics, Health Education England's family-history tools — card-based aide-memoires and worksheets — are widely distributed. They prompt patients (and clinicians) to capture a three-generation history without demanding specialist knowledge of notation. Similar tools exist internationally, including US CDC "My Family Health Portrait" and Surgeon General's tools.
Their value is in patient accessibility and intake time-saving, rather than in analytical power. A completed worksheet still needs to be entered into a structured system for inheritance pattern analysis and risk model runs. The combination — worksheet for intake, software for analysis — is the practical clinical workflow in many services today.
Template-style exports from digital software
Modern pedigree software can produce template-style outputs for situations where the paper artefact is still wanted. A PDF export of a completed pedigree is, effectively, the template filled in correctly and consistently — the notation is enforced, the structure is checked, and the result can be included in the clinical record or shared with the patient as their copy. This eliminates one of the main drawbacks of templates (inconsistent hand-drawing) while preserving the value of a printable artefact.
In practice, many services now produce their "pedigree charts" as software-generated PDFs rather than hand-completed paper templates, and use the paper worksheet only for intake.
Migrating from template-based workflows to digital
Services transitioning from paper-based pedigree records to digital typically adopt a staged approach:
- Keep the intake tool. The family-history worksheet or paper template remains for patient intake because patients are familiar with it and completion rates are good.
- Move the analytical work into digital. Data from the intake form are entered into the pedigree software; analyses (inheritance patterns, risk models) run there.
- Produce a software-generated PDF for the clinical record. This is cleaner than scanned handwritten paper and searchable if stored with metadata.
- Retire historic paper where feasible. Paper archives remain important for older records, but current pedigrees sit in the digital system.
The transition is rarely all-or-nothing. Paper templates continue to have specific uses even as the clinical record becomes digital.
How Evagene supports this
Evagene produces template-style PDF exports of completed pedigrees with full NSGC-compliant notation, suitable for the clinical record or for sharing with the patient as a printed artefact. PNG and SVG exports are also available for inclusion in reports, slides, and teaching materials — covering most of the use cases historically served by blank templates plus hand-drawing.
Services that use paper family-history worksheets for patient intake can continue to do so: the data are entered into Evagene after the intake, and the software produces the clinical pedigree, runs the analyses (Mendelian inheritance, BRCAPRO, MMRpro, PancPRO, consanguinity detection, batch risk screening), and archives the structured record. Pedigree images — including completed paper templates — can be imported via OCR, which reconstructs the pedigree as structured data in Evagene.
For teaching, Evagene's gesture drawing mode works well for live demonstration, but a blank printable template remains valuable for first-principles student work. The two approaches are complementary rather than competitive.
Frequently asked questions
What is a pedigree chart template?
A blank standardised form for recording family history, usually printed or in a slide deck.
When is a template enough?
For teaching, patient-completed intake, bedside documentation, and quick reference.
What are the limitations?
No enforced notation, no analytics, no structured data, difficult to share and update.
Is there a standard UK template?
Health Education England's family-history card is widely used.
Can Evagene produce a template-style PDF?
Yes — PDF, PNG, and SVG exports are built-in.
Do digital tools replace templates?
For analytical work, yes; for patient intake and teaching, often alongside rather than instead of templates.
