[Dermatoglyphic analysis of patients with hypertrophic cardiomyopathy]
Insights
Dermatoglyphic analysis of hypertrophic cardiomyopathy (HCM) patients revealed subtle handprint differences, including increased double loops and altered palmar line patterns. These findings are not significant enough for practical screening of at-risk individuals.
Area of Science:
- Genetics and Human Biology
- Cardiovascular Research
- Dermatoglyphics
Context:
- Hypertrophic cardiomyopathy (HCM) is a complex genetic heart disease.
- Dermatoglyphics, the study of hand and footprints, offers insights into developmental variations.
- Previous research has explored dermatoglyphic markers in various genetic conditions.
Purpose:
- To investigate potential dermatoglyphic abnormalities in individuals with hypertrophic cardiomyopathy.
- To determine if specific finger and palm print patterns are associated with HCM.
- To assess the utility of dermatoglyphic analysis for screening HCM in at-risk families.
Summary:
- A dermatoglyphic analysis was conducted on 100 individuals (69 men, 31 women) diagnosed with hypertrophic cardiomyopathy.
- Two significant dermatoglyphic differences were observed compared to controls: an increased frequency of double loops on the fingers and a more longitudinal course of the main palmar line, frequently terminating in area 3 and less often in area 5.
- No correlations were found between these dermatoglyphic findings and disease severity or family history.
Impact:
- The identified dermatoglyphic variations in HCM patients are not sufficiently distinct for practical application in screening individuals within families predisposed to the condition.
- This study highlights the need for further research into specific genetic and developmental pathways influencing both HCM and dermatoglyphic patterns.
- The findings suggest that while subtle associations may exist, dermatoglyphics alone are unlikely to serve as a primary diagnostic or screening tool for hypertrophic cardiomyopathy.
Abstract:
Complete dermatoglyphic analysis of the hands in 69 men and 31 women with hypertrophic cardiomyopathy revealed only two significant abnormalities. In both sexes the total frequency of double loops on the fingers was increased (table 1) and the main palmar line had a more longitudinal course on the palm with its termination more frequently in area 3, less frequently in area 5 than in both compared controls (table 2). The differences are, however, not marked enough to use them in practice to screen affected individuals in families at risk. No differences were revealed in relation to the severity of the disease and the genealogical situation in the pedigree.
