Human Genetics
|October 2, 1979
Summary
The human GOTM gene exhibits polymorphism, with two common alleles (GOTM1 and GOTM2) confirmed in red blood cells. The GOTM1 allele frequency was found to be 0.981 in a German population sample.
Area of Science:
- Human genetics
- Biochemistry
- Population genetics
Background:
- Genetic polymorphism in humans is crucial for understanding population diversity and disease susceptibility.
- The GOTM gene's role and allelic variations require detailed investigation.
Purpose of the Study:
- To investigate the genetic polymorphism of the human GOTM gene.
- To confirm the allelic model and determine allele frequencies in a specific population.
Main Methods:
- Starch gel electrophoresis was employed to analyze GOTM polymorphism in red blood cells.
- Family data, specifically 640 mother-child pairs, were used to validate the genetic model.
Main Results:
- The study confirmed a formal genetic model with two common alleles, GOTM1 and GOTM2, at the autosomal GOTM locus.
- The frequency of the GOTM1 allele in the southwestern German sample was determined to be 0.981 ± 0.003.
Conclusions:
- The findings support the established genetic model for human GOTM.
- The high frequency of GOTM1 suggests its predominant role in the studied population.
