Abstract
Dermatoglyphic studies were carried out in 10 patients (8 boys and 2 girls) with ectodermal anhidrotic dysplasia, and compared with 200 healthy controls. Severe malformations of dermal ridges among index cases made quantitative analysis inaccesible and therefore only qualitative dermatoglyphic parameters were examined. The most significant dermatoglyphic patterns of hands and feet which differentiated the patients from the controls were as follows:
1. significantly higher frequency of arches on the fingertips (boys: 31.4% vs 2.4%; girls: 15% vs 6%),
2. higher frequency of arches on the toetips (boys: 45.7% vs 11.7%; girls: 30% vs 16.4%),
3. absence of whorls on the finger and toetips,
4. increased incidence of double or ulnar loops in the hypothenar area (boys: 78.5% vs 13.0%; girls: 100% vs 15.5%),
5. significant increase in the incidence of Sydney line on the hands (boys: 56.2% vs 2.0%; girls: 50% vs 6%),
6. severe ridges malformations revealing a characteristic appearance of “ridge hypoplasia” or “ridge dissociation”.
