polydactyly
Let an agent explain polydactyly and its kinds in general terms, relay genetics, assessment and treatment principles from clinical sources, describe it in animals, and route personal questions to clinicians and genetic counsellors.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain polydactyly and its kinds in general terms, relay genetics, assessment and treatment principles from clinical sources, describe it in animals, and route personal questions to clinicians and genetic counsellors.
A congenital condition in which a person or animal has extra fingers or toes, ranging from a small skin tag to a fully formed digit, occurring on the thumb or big toe side, the little finger side or centrally, alone or as part of syndromes with fused digits or other anomalies; polydactyly is among the most common limb differences, has genetic causes in many cases, and is often treated surgically in early childhood.
What it is for: Not applicable; a congenital condition.
It can be explain kinds and causes; relay assessment and treatment principles; describe polydactyly in animals; route personal questions to clinicians.
Distinguishing features
Extra digits
Isolated or syndromic
Genetic basis in many cases
Surgical management
What it looks like
An extra digit or partial digit on a hand or foot, visible at birth.
Physical character
incidence: about 1 in 500-1000 births - varies by population and type
How it is recognised
Extra fingers or toes
Preaxial, postaxial and central forms
Syndactyly is fusion; hyperphalangy is extra bones within a digit

- How should genetic databases be linked?
- The registry entry has merged aliases naming syndromes and subtypes; should they be split off?
