with clinical features

The powerful trait search allows you to input multiple observed features to identify a list of matched syndromes. By adjusting the strength of each attribute the search is refined to generate a more specific list of syndromes. Clicking a syndrome link provides quick access to detailed clinical descriptions of the candidate syndrome, individual clinical case reports and images of observed physical characteristics. Notation of unique attributes and syndromes with shared features help you with differential diagnosis.
