Most likely diagnostic options for a broad palm (listed order of conditions below is made according overall statistical chance to find this hand sign combined with the condition):
- ASSOCIATED MEDICAL CONDITIONS:
• trisomy 21 (= Down syndrome) [~50?% | 1:700 | weight: 0.005]
• fragile-X syndrome [~70?% | 1:5.000 | weight: 0.0009]
• achondroplasia (= dwarfism) [~95+% | 1:25.000 | weight: 0.0002]
• trisomy 13 (= Patau syndrome [~50?% | 1:15.000 | weight: 0.0002]
• 5p- syndrome (= cri-du-chat syndrome) [~50?% | 1:30.000 | weight: 0.0001]
- ASSOCIATED PSYCHOLOGICAL CONDITIONS:
[1st figure = prevalence hand sign in condition | 2nd
figure = prevalence condition in GP | 3rd figure =
estimated weight hand sign for condition relative
to GP (>1,00 = high impact)]
- 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; high hand index is typically seen in Down syndrome, very high hand index in achondroplasia.
[For every 1000 broad palm cases in the general population (GP) there
are only 3 trisomy 21 cases with a broad palm, etc.]
