Red cell enzyme polymorphisms in the greek populations

Area of Science:

• Biochemistry
• Population Genetics
• Genetics

Background:

• Red blood cell enzymes are crucial for cellular function.
• Genetic variations in these enzymes can indicate population diversity and evolutionary history.
• Previous studies have established baseline frequencies in various European populations.

Purpose of the Study:

• To determine the frequencies of variant forms of six red cell enzymes in nine distinct Greek populations.
• To compare these frequencies with those reported in other European populations.
• To investigate potential genetic distinctions between Greek and Bulgarian populations.

Main Methods:

• Analysis of red cell enzyme variant frequencies.
• Sampling across nine geographically diverse Greek populations.
• Comparative analysis with existing European and Bulgarian population data.

Main Results:

• The allele frequencies for adenylate kinase, adenosine deaminase, phosphoglucomutase, acid phosphatase, 6-phosphogluconate dehydrogenase, and glutathione reductase were cataloged in Greek populations.
• Observed frequencies were largely consistent with those found in other European groups.
• Significant differences in specific enzyme alleles (6-phosphogluconate dehydrogenase, phosphoglucomutase, acid phosphatase) were noted between Greeks and Bulgarians.
• Macedonian populations exhibited genetic profiles similar to other Greeks, distinct from Bulgarians.

Conclusions:

• Greek populations share common red cell enzyme variant patterns with broader European populations.
• Distinct genetic markers in specific red cell enzymes support the separate ethnic origins of Greeks and Bulgarians.
• The genetic data reinforces the unique identity of Greek populations, including those in Macedonia, in contrast to Bulgarian populations.
