2. Accurate diagnosis of the syndrome
better decision making and communicating :
Prognosis.
Treatment options.
Occult abnormalities.
Recurrence risk.
Pathogenesis.
Natural Hx.
Until february 2013 542 syndromes
How to remember??? difficult
How to diagnosis ?? more difficult..

4. Syndrome Identification :
Making a diagnosis, even if it’s a bad diagnosis,
is more useful for patients than having no diagnosis
but a
wrong diagnosis is worse than no diagnosis.
The first step towards an accurate diagnosis of a
syndrome is by extensive phenotypic analysis

58. Summary
a bad diagnosis (not wrong diagnosis) is more useful
than having no diagnosis.
The principles in dysmorphology include the
determination of the underlying pathogenic mechanism,
and if it is a single system or multi-system defect.
The first step towards an accurate diagnosis of a
syndrome is by extensive phenotypic analysis
