[Dermatoglyphics in beta-thalassemia major].

The features of dermatoglyphics in 39 children with beta-thalassemia major and in 47 their parents are studied. The control were 70 healthy children. The patients with beta-thalassemia had more often the prevailence of whorls over other finger patterns. There was an increase of the "atd" angle and some increase in the ridge of counts. Parents had also an increase of the amount of whorls, but this increase was less pronounced than under beta-thalassemia. The changes of the dermatoglyphics in parents of children affected with beta-thalassemia major are suggested to ba a phenotypic feature of heterozygous carrier of the mutant gene.
