[Dermatoglyphic findings in children with mucoviscidosis and their parents].

Dermatoglyphics were investigated in 37 children with cystic fibrosis (17 boys, 20 girls, 4 pairs of them sibs) between two months and 17 years of age and in 30 of their parents. For the pattern distribution there were no differences between the patients or their parents respectively and the general population except for a higher tendency of reduction (O and X) of the main line C. Concerning the ridge structure in the children, all variations from normal ridges over enlarged sweat gland pores to complete ridge dissociation were found. For the degree of these structural changes and the jontophorese values a correlation coefficient r=+0.39 (p <0.05) resulted. While the frequency of ridge dissociation on the hypothenar is 56.8 % in the children with cystic fibrosis, the parents have a frequency of 23.4%. This value is lying between that of their children and the general population (13.4%).
