EsD*5 gene frequency in Tuscany (Italy)

Area of Science:

• Genetics
• Population Genetics
• Biochemistry

Background:

• Human red cell esterase D (EsD) is an enzyme with known genetic polymorphisms.
• Understanding the distribution of EsD alleles is important for population genetics and forensic applications.
• Previous studies have characterized EsD polymorphism in various populations.

Purpose of the Study:

• To investigate the distribution of the extended human red cell esterase D (EsD) polymorphism in a Tuscan (Italy) population sample.
• To determine the allele frequencies of EsD variants in this specific European population.
• To assess the potential utility of the extended EsD polymorphism in forensic contexts, such as paternity testing.

Main Methods:

• Agarose gel isoelectric focusing was employed to analyze the EsD polymorphism.
• A population sample from Tuscany, Italy, was utilized for the study.
• Gene frequencies for identified EsD alleles were estimated.

Main Results:

• The estimated gene frequencies for the studied EsD alleles were: EsD*1 = 0.864, EsD*2 = 0.115, and EsD*5 = 0.021.
• The frequency of the EsD*5 allele in the Tuscan population was found to be comparable to those reported in other European populations.
• The observed distribution of EsD alleles provides a genetic profile for the Tuscan population.

Conclusions:

• The extended esterase D polymorphism in the Tuscan population is characterized by specific allele frequencies.
• The EsD*5 allele frequency aligns with patterns observed in other European groups.
• The extended EsD polymorphism demonstrates potential usefulness in enhancing the accuracy of paternity testing.
