Dermatoglyphic studies of myocardial infarction patients.

Dermatoglyphic traits were studied in a sample of 834 subjects selected from a cohort of some 8,000 living Japanese men, under a long-term study of heart disease in Hawaii. All of them were born between 1900 and 1919. Among them, 100 subjects had had positive diagnosis of myocardial infarction (MI). The present study included comparisons between the MI patients and the remaining group of all digital dermal pattern types and ridge counts by digit, by hand, and by individual. The MI patients had significantly higher frequency of true whorls, double loops and less ulnar loops and tented arches. Total and absolute ridge counts were significantly higher (less than 0.05) in all digits in favor of the MI patients. Similar trends were observed in analyses by digit and by hand. These observations suggest an antenatal origin of certain types of coronary disease.

Genetics of asymmetry in dermatologlyphic traits.

Differences between the right and left hand in ridge counts and pattern type counts were analyzed using data obtained from 711 families consisting of all parents and 2,466 children. Heritability estimates for each trait were derived from regressions of offspring on either parent or average value of the two parents, and from full-sib correlations. These estimates varied from 0.09 for bimanual difference in the number of arches to 0.24 in the number of ulnar triradii. The low expected value of heritability for bimanual difference in dermatoglyphic traits was demonstrated.

Dermatoglyphic traits in patients with cardiovascular disorders.

Dermatoglyphic studies were carried out on 800 Japanese subjects. Digital dermal pattern types were classified into true whorls, double loops, ulnar loops, radial loops and arches. Both total and absolute ridge count were recorded. Subjects with hypertension, angina pectoris and myocardial infarction were compared with the remaining group of others who had not yet developed any of these disorders. Individuals with myocardial infarction had a significantly higher frequency of true whorls and a correspondingly lower frequency of ulnar loops than the control group. Total and absolute ridge counts were also significantly higher in myocardial infarction. Individuals with hypertension and angina pectoris were not significantly different in most dermatoglyphic traits from the controls. These observations suggest that antenatal factors may contribute to the etiology of myocardial infarction in man.

Genetic parameters of dermal patterns of ridge counts.

Dermatoglyphic traits including ridge counts and pattern type counts on fingers were studied in 711 families representing six racial groups in Hawaii. Heritability tesimates were derived from regressions of offspring on father, mother and mid-parent values as well as from full-sib correlations. These estimates varied from 0.23 for radial loops to 0.80 for total ridge count. The heritability estimates were lower for ridge counts of single hands or single digits.
