Glucose-6-phosphate dehydrogenase deficiency and blood groups in northern Sardinia
Human Heredity
|January 1, 1985
Insights
Glucose-6-phosphate dehydrogenase deficiency is common in Sardinian males (6.56%). Blood group frequencies, including Rhesus and A1A2BO systems, show unique patterns in northern Sardinia compared to mainland Italy.
Area of Science:
- Genetics
- Hematology
- Population Studies
Background:
- Blood group antigen frequencies and genetic disorders vary geographically.
- Understanding these variations is crucial for transfusion medicine and population genetics.
Purpose of the Study:
- To investigate the prevalence of Glucose-6-phosphate dehydrogenase (G6PD) deficiency.
- To analyze the distribution of A1A2BO, Rhesus, and Kell blood group systems in northern Sardinia.
Main Methods:
- Analysis of blood samples from 28,439 blood donors native to northern Sardinia.
- Phenotypic frequencies of G6PD deficiency and blood group systems were determined.
Main Results:
- The frequency of G6PD deficient males was 6.56%.
- Elevated frequencies of Rhesus factors r, D, and CDe were observed compared to continental Italy.
- Significant variations in A1A2BO and Rhesus blood group systems were noted within Sardinia.
Conclusions:
- Northern Sardinia exhibits distinct genetic profiles for G6PD deficiency and major blood group systems.
- These findings highlight regional genetic heterogeneity relevant to blood transfusion services and anthropological studies.
Abstract:
Glucose-6-phosphate dehydrogenase deficiency, A1A2BO, Rhesus and Kell systems were investigated in a sample of 28,439 blood donors native of northern Sardinia. The frequency of deficient male individuals was 6.56%. Higher values of r, D, and CDe compared to the averages for continental Italy were observed. Variations within the island were found in the A1A2BO and Rhesus blood group systems.
