Genetics of plantar interdigital ridge counts

Area of Science:

• Anthropometry
• Human Genetics
• Dermatoglyphics

Background:

• Interdigital ridge counts on soles are a heritable trait.
• Previous studies have explored the genetics of specific ridge counts (a-b, b-c, c-d).

Purpose of the Study:

• To investigate the genetics of sole interdigital ridge counts in a homogeneous Brahmin population from Andhra Pradesh, India.
• To define and evaluate the inheritance of total plantar interdigital ridge counts (TPtIRC).

Main Methods:

• Analysis of a-b, b-c, and c-d ridge counts.
• Definition and assessment of total plantar interdigital ridge counts (TPtIRC).

Main Results:

• The genetics of a-b, b-c, and c-d ridge counts in this population do not fully align with prior research.
• The mode of inheritance for TPtIRC was evaluated.

Conclusions:

• Current findings suggest a need to re-evaluate the established genetic models for plantar interdigital ridge counts.
• Further research is warranted to fully elucidate the inheritance patterns of these dermatoglyphic traits.
