VARIANTIS Encyclopedia of Human Anatomical Variation
A morphology-first encyclopedia documenting anatomical variants, classification systems and morphology-derived clinical significance.
Core principle: Clinical significance is addressed only when it follows directly from documented morphology and topographical relationships..
Two pillars of VARIANTIS
Anatomical Variations
Systematic documentation of human morphological variation, organised by anatomical domain and evaluated against the available evidence.
Clinical Significance
Clinical relevance is interpreted only when it follows directly from documented morphology and established anatomical relationships.
From morphology to clinical significance
VARIANTIS follows a morphology-first framework. Anatomical variants are first defined, classified where possible, evaluated against the available evidence and interpreted within their topographical context. Clinical significance is addressed only when it follows directly from this anatomical framework.
How VARIANTIS entries are built
Each VARIANTIS entry is developed from anatomical evidence, classification systems, prevalence data and morphology-derived clinical interpretation.
