Disproportionate fetal growth and fingerprint patterns

Area of Science:

• Dermatoglyphics
• Fetal Development
• Maternal-Fetal Health

Background:

• Fingerprint whorl patterns develop during fetal life.
• These patterns have been linked to adult hypertension.
• The developmental origins of dermatoglyphic patterns and their relation to fetal growth are not fully understood.

Purpose of the Study:

• To investigate the association between fingerprint whorl counts in term infants and fetal growth parameters.
• To explore the influence of maternal nutritional status on fingerprint whorl development.
• To examine potential links between fetal development, fingerprint patterns, and later health outcomes like hypertension.

Main Methods:

• Analysis of fingerprint whorl patterns in 180 term infants.
• Measurement of infant anthropometric data, including abdominal circumference.
• Assessment of maternal skinfold thicknesses (subscapular and triceps) as indicators of nutritional status.

Main Results:

• Higher fingerprint whorl counts in infants were associated with smaller abdominal circumference (P=0.09) and a higher head-to-abdominal circumference ratio (P=0.008).
• These associations were independent of maternal-infant whorl count correlations.
• Infant whorl count correlated with maternal nutritional status: increasing subscapular skinfolds (P=0.03) and decreasing triceps skinfolds (P=0.02).

Conclusions:

• Fingerprint whorl patterns in newborns are associated with specific fetal growth metrics.
• Maternal nutritional status during pregnancy may play a role in the fetal development of fingerprint whorl patterns.
• These findings suggest a potential common developmental origin for fingerprint patterns and predisposition to conditions like adult hypertension.
