DERMATOGLYPHIC STUDY OF KLINEFELTER’S SYNDROME 2.PALMAR a－b RIDGE COUNTS

摘要

The palmar a-b ridge counts were investigated in 51 cases of Klinefelter's syndrome. The total count in this syndrome was 72 .51 in average which did not differ from the normal male and female controls on a statistic analysis, although the low palmar a-b ridge count was previously reported by other investigators. Japanese with Klinefelter's syndrome show the lower a-b ridge counts than those in U.S.A or Europe. This is probably due to the racial differences.
