Most likely diagnostic options for a broad palm (ranked by 'weight' for the general population):
- ASSOCIATED MEDICAL CONDITIONS:
• trisomy 21 (= Down syndrome) [~50?% | 1:700 | weight: 0.004]
• fragile-X syndrome [~70?% | 1:5K | weight: 0.0009]
• achondroplasia (= dwarfism) [~95+% | 1:25K | weight: 0.0002]
• trisomy 13 (= Patau syndrome [~50?% | 1:15K | weight: 0.0002]
• 5p- syndrome (= cri-du-chat syndrome) [~50?% | 1:30K | weight: 0,0001]
- ASSOCIATED PSYCHOLOGICAL CONDITIONS:
[1st figure = prevalence hand sign in condition | 2nd
figure = prevalence condition in GP | 3rd figure =
estimated hand sign weight for condition relative
to GP (>0,5 = present in majority of GP)]
- Recommended sources involving broad palms:
• Earth hands & Air hands!
• PB/PL ratio: data for 19 human populations!
broad palms are often seen in males & Middle East people; broad palms are typically seen in Down syndrome, very broad palms in achondroplasia.
[In every 1000 broad palm cases in the general population (GP) there
are only 4 trisomy 21 cases with a broad palm, etc.]
