Dermatoglyphs in children with mitral valve prolapse

Area of Science:

• Dermatoglyphics
• Cardiology
• Pediatrics

Background:

• Mitral valve prolapse (MVP) is a cardiac condition affecting heart valve function.
• Dermatoglyphics, the study of fingerprints and palm prints, can offer insights into developmental conditions.
• Previous research suggests potential links between dermatoglyphic patterns and certain congenital abnormalities.

Purpose of the Study:

• To examine the frequency of digital arches in Singaporean school children diagnosed with mitral valve prolapse (MVP).
• To compare dermatoglyphic findings, specifically digital arch patterns, in MVP patients versus a control group.
• To assess for other dermatoglyphic abnormalities in children with MVP.

Main Methods:

• Clinical diagnosis of MVP confirmed by two-dimensional echocardiography in 50 children (35 Chinese, 15 Malay).
• Dermatoglyphic analysis focused on the presence and frequency of digital arches.
• Comparison of arch frequencies with a control group of 50 children without MVP and population data for Singapore.

Main Results:

• Four Chinese children (approximately 11.4%) exhibited digital arches; no Malay children had arches.
• The frequency of digital arches in MVP patients was not statistically higher than in controls.
• No significant differences were observed when compared to general Singaporean Chinese and Malay population arch frequencies (2.0% and 2.9%).
• No other dermatoglyphic abnormalities, including the atd angle, were identified in the MVP group.

Conclusions:

• Digital arch frequency does not appear to be a significant dermatoglyphic marker for mitral valve prolapse in this cohort of Singaporean children.
• Further research may be warranted to explore other potential dermatoglyphic associations with MVP or related conditions.
• Standard dermatoglyphic analysis, including the atd angle, did not reveal additional abnormalities in children with MVP.
