Dermatoglyphics in turner syndrome

Finger and Palmar dermatoglyphics in 25 karyotypically proven cases of Turner syndrome representing Northwestern region of India are presented and compared with those obtained on their 102 normal female counterparts. Predominance of ulnar loops over other patterns was recorded in turner patients. Mean total finger ridge count in Turner syndrome (147.4) remained higher than the normal females (121.1). c-d interdigital ridge count in turners remained significantly (p≤0.05) higher than their normal female counter-parts. In contrast to their western counterparts distal placement of axial triradius in both the palms of none of the Turner syndrome patients representing the current series was recorded. Occurrence of whorls and arches in hypothenar region of 12% and 4% was respectively noticed in right palm of patients. The use of distinctive dermatoglyphic features recorded amongst Turner syndrome patients representing this study may be made to corroborate diagnosis of this entity in settings where facilities to carry out karyotyping do not exist.
