- Abstract
- Total ridge counts in normal Korean males and Jemales as well as individuals with sex-chro-
mosomal aberrations were reported in this study.
The mean total ridge count (TRC) in three hundreds and twenty-five school boys and too
hundreds and eighty-nine school girls was 146±40. 2 S.D. (range, 88-208) and 132. 2±48.5 S.D.(range 74-203), respectively. The examinations of finger-tip pattern types, ridge counts and total ridge count in a patient
with 45, XO Turner’s syndrome and a patient with 47, XXY Klinefelter’s syndrome revealed
significant differences especially in total ridge count, 164 for Turner’s syndrome and 86 for Klinefelter’s syndrome.
The total ridge count is significantly higher in individuals with Turner’s syndrome and
significantly lower in individuals with Klinefelter’s syndrome than that for normal individuals
but there is so much overlap in distributions that total ridge count is not useful as a diagnosticaid.
of syndromes associated with numerical aberrations of sex-chromosomes.
