Summary
This study analyzed Phosphoglucomutase 1 (PGM1) gene variants in Chinese blood donors. PGM1 W21 was identified as the most common variant, with a phenotype frequency of 0.8%.
Area of Science:
- Biochemistry
- Genetics
- Population Genetics
Background:
- Phosphoglucomutase 1 (PGM1) is a crucial enzyme in carbohydrate metabolism.
- Understanding PGM1 gene diversity is important for population genetics and forensic science.
Purpose of the Study:
- To determine the allele and phenotype frequencies of PGM1 in a Chinese blood donor population.
- To identify and characterize common PGM1 variants within this demographic.
Main Methods:
- Thin-layer isoelectric focusing on agarose was employed for PGM1 phenotyping.
- Analysis included 1,128 Chinese blood donors.
Main Results:
- The study determined PGM1 gene frequencies: 1A (0.6005), 1B (0.1500), 2A (0.1510), 2B (0.0973), and variants (0.0058).
- PGM1 W21 was the most prevalent variant, observed with a phenotype frequency of 0.8%.
- Other identified variants included PGM1 W2, W3, W6, and W9 (or W10).
Conclusions:
- The PGM1 genetic profile of Chinese blood donors was established.
- PGM1 W21 represents a significant genetic marker in the Chinese population.
