Most likely diagnostic options for a single crease on pinky finger - NOTICE: this condition nearly always involves 3 finger bones, so there is no bone missing (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) [~18% | 1:700 | weight: 2.57]
trisomy 18 (= Edwards syndrome) [~80% | 1:6.000 | weight: 1.33]
trisomy 13 (= Patau syndrome) [~5% | 1:15.000 | weight: 0.03]
Cornelia de Lange syndrome [~1% | 1:15.000 | weight: 0.007]

Trisomy 18 & 21 syndrome combination: single palmar crease (simian line) + single interphalangeal crease on digit 5.

Quick summary:
a large majority (~75%) of hands featured
with a single crease on one or both 5th fingers
involves trisomy 21 or trisomy 18.

PS. Cases of trisomy 18 rarely reach adulthood, therefore
trisomy 21 is the most likely option in adults
(indicated by the presented statistics).

[For every single crease case in the general population (GP) there are 2.5 trisomy 21 cases with a single crease,
1.3 trisomy 18 cases with a single crease, 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!
