“…The finding agrees with their observation that ridge width increases with the number of sex chromosomes and confirms their suggestion that the Y chromosome has a greater effect on this character than an additional X. The difference between the means for XYY and XY was 34 ,tm (Saldafia-Garcia, 1973/1974 while that between the means for XXX and XX was 23 ,um. Another trait influenced by age and also investigated was the maximal atd angle.…”

“…In the abnormal group the triradius z' was more common than z" and its frequency was more than double that observed in control females. A similar peculiarity was observed in XYY males (Saldafia-Garcia, 1973/ 1974. The finding again confirmed the observation that zygodactyly on the palms seems to be more frequent in all sex chromosomal aberrations (Penrose and Loesch, 1970b).…”

“…High counts were unusual and the mean total ridge count was 104.94 ± 6.12 ridges (Table II). When the mean values of the total finger ridge-count between control and triple X females were compared, the differences between their means, 22 ridges was significant (3.5 times its standard error) and double that observed between control males (145, see and XYY (135, see Saldafna-Garcia, 1973/1974. This finding suggested that the addi- Control population (after Holt, /1964.…”

Summary. The dermatoglyphic findings from 54 females with XXX sex chromosomes are reported. Sole prints were available for study in 33 cases.Compared with female controls, an excess of radial loops and arches and a reduced mean for total finger ridge-count were the main peculiarities on the fingers.On the palms, the absence of pattern in areas I and II, and wider ridges in the a-b interval were characteristics observed. Previous findings by other authors with respect to: (1) zygodactylous tendency in the palms, (2) tendency for the ridge width to increase with the number of sex chromosomes, and (3) greater effect of an extra X chromosome in pattern size reduction but lesser influence on ridge width than an additional Y chromosome, were confirmed.On the soles, pattern intensity was above the control average. There was a significant deficit of proximal loops in area III but an excess of proximal V together with triradius h. Triradius pi and zygodactylous z' were also significantly reduced in frequency.General findings with respect to the soles of patients with X, XXX, XXY, and XYY sex chromosomal abnormalities are also reviewed. Discrepancies are apparent and further studies are needed.Finally, a dictionary (Appendices 1 and 2) is provided which gives the frequencies ofthe complete pattern configurations on the palms and soles of XXX females.

“…In the present study, however, no significant difference was found among patient and normal materials. Though it has been observed that the palmar pattern intensity generally decreases with the increase in number of sex chromosomes (Penrose and Loesch, 1970;Saldana-Garcia, 1973 and1975), the present data failed to reveal a significant decrease in this trait in the XXY group. Thus, the dermatoglyphic deviation of the Klinefelter's syndrome from the normal males and females was less remarkable in our subjects,…”

“…However, it is clear that in Turner's syndrome (45, X) there is a significant in crease [11][12][13][14][15][16], and in Klinefelter's syn drome (47, XXY) a significant decrease in the a-b ridge count [17]. There may be a small ridge count reduction in XYY males [18]. There is some suggestion of a linear decrease in the a-b ridge count as the num ber of X chromosomes increases [14,19], akin to the relationships between the sex chromosome complement, the TRC, and the mean ridge breadth [20].…”

Distribution and Sex Variation of the a-b Ridge Count

A study of the distribution of the summed (right plus left) a-b ridge count in 1,000 normal subjects showed a significant deficit of counts at the two ends of the range. In males the distribution was significantly different from a normal distribution, but in females a similar trend did not reach statistical significance. No significant sex difference was found, although it is known that abnormal sex chromosome complements may affect the a-b ridge count. The influence of the sex chromosome complement on the a-b ridge count appears to be smaller than the effect of the sex chromosome complement on the total finger ridge count. The a-b ridge count is probably also less genetically determined than the total finger ridge count.
