High frequency of Ina antigen among Iranians and Arabs

Area of Science:

• Immunogenetics
• Population genetics
• Serology

Background:

• The Ina antigen is a red blood cell surface marker.
• Understanding antigen distribution is crucial for transfusion medicine and population studies.

Purpose of the Study:

• To determine the frequency of the Ina antigen in various global populations.
• To investigate the polymorphic nature of the Ina antigen across different ethnic groups.

Main Methods:

• Population-based serological testing.
• Analysis of Ina antigen presence in blood samples from diverse ethnic groups.

Main Results:

• The Ina antigen exhibited polymorphism in Arab (11.8%) and Iranian (10.6%) populations.
• The Ina antigen was found to be absent in samples from Thailand, Indonesia, China, and Parsi individuals.

Conclusions:

• The Ina antigen distribution varies significantly across different ethnic groups.
• The polymorphic nature of the Ina antigen in specific populations has implications for blood banking and genetic research.
