“…In the palmar patterns of this syndrome, no characteristic findings, such as the increased hypothenar patterns associated with an ulnar triradius seen in the XXYY type (Shiono et al,, 1977), have been noted (Schaumann and Alter, 1976). On the other hand, the frequencies of several palmar pattern elements in the XXY type were reported to be different from those of normal male and female subjects (Holt, 1968;Cushman and Soltan, 1969;Penrose and Loesch, 1970). The purpose of this study is, therefore, to clarify these contradictory findings.…”
