Carbonic anhydrase-I polymorphism in a Philippine aboriginal population

Area of Science:

• Human genetics
• Biochemistry
• Anthropology

Background:

• Carbonic anhydrase-I (CA1) is a crucial enzyme involved in various physiological processes.
• Genetic polymorphism within human populations provides insights into evolutionary history and migration patterns.

Purpose of the Study:

• To investigate the genetic polymorphism of carbonic anhydrase-I (CA1) in an aboriginal group from Mindanao, Philippines.
• To determine the frequency of CA1 variants in this population.
• To assess the potential of CA1 variants as anthropological markers.

Main Methods:

• Electrophoresis was employed to analyze carbonic anhydrase-I (CA1) isozymes.
• Allele frequencies were calculated based on electrophoretic patterns.

Main Results:

• A high frequency of carbonic anhydrase-I (CA1) polymorphism was detected in the studied aboriginal group.
• The estimated frequency of the variant allele was 0.256.
• A specific variant isozyme, CA1 3Negrito (CA1 3N), was identified and found to be electrophoretically identical to the 'Guam' variant.

Conclusions:

• The significant CA1 polymorphism in this Philippine population highlights its potential as an anthropological marker.
• The CA1 3Negrito variant may be a useful genetic tool for studying population dynamics and historical movements in the Western Pacific.
• Further research is warranted to explore the distribution and significance of CA1 variants across different Western Pacific populations.
