Narrow palm: PB/PL < 0,79 (= low palm width vs palm length ratio)

Prevalence in general population (GP): relatively common [~16% | 1:1 | weight: 1.00]

NOTICE: narrow palms are more common in females than males, also more common in East Asians

Most likely diagnostic options for a narrow palm (listed order of conditions below is made according overall statistical chance to find this hand sign combined with the condition):


Marfan syndrome [~90?% | 1:6.000 | weight: 0.001]
Prader-Willi syndrome [~50?% | 1:15.000 | weight: 0.0002]



[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 narrow palms:

Water hands & Fire hands!
PB/PL ratio: data for 19 human populations!
Broad palm: PB/PL > 0,81.

Quick summary:
narrow palms are often seen in females & East Asians people; (very) narrow palms typically seen in Marfan syndrome.

[For every 1000 narrow palm cases in the general population (GP) there is only 1 Marfan syndrome case with a narrow hand, etc.]

NOTICE: Keep in mind that every single hand sign always bares the potential
to have an association with multiple psychology- and/or health related themes;
a solid assessment always requires a consideration of hand sign combinations!
